RIMEX TPMS TyreSense Wheel Sensor
Purpose
The TyreSense Sensor Guide is your operation and installation guide TyreSense
wheel sensors.
Required background knowledge
To ensure you safely and correctly install your TyreSense hardware, knowledge
of the tire industry and vehicle maintenance is required.
Safety requirements
The following regulations must be adhered to in the installation and maintenance of all TyreSense equipment:
- All persons involved in the installation and maintenance of the TyreSense system must follow all safety precautions as established on customer premises.
- All TyreSense system equipment (including all hardware and software) must be accessible by authorized personnel only.
- All cables with exposed wires must be installed by a qualified electrician.
- All tire sensors must be installed by an authorized and qualified and tire technician.
Magnet safety protocol
The magnetic mounts are shipped in Styrofoam packing and should be stored in a
safe location until they are to be installed. The magnetic mounts should be
handled by qualified personnel only.
The Magnetic Mount Wheel Sensors should not be altered in any way. TyreSense
assumes no responsibility for sensors or mounts that have been modified by the
user.
The Magnetic Wheel Sensor procedure outlined in this manual is a guide and
should be approved by the site supervisor before installation. Exhibit caution
when working with magnets.
Hazards associated with magnets
The magnetic mounts exert strong attractive forces on other magnets and
ferromagnetic objects. They can cause small ferromagnetic objects to become
projectiles and can cause personal injury and equipment damage.
The magnets also present a pinching hazard when brought close to each other
near skin. The magnets are hard to separate once they have been brought
together and can shatter if brought together too quickly. Do not bring the
magnets within 25 cm (10 in) and always handle the magnets with care.
Magnetically sensitive equipment
Magnets generate magnetic fields that can cause damage to or impair the
operation of magnetically sensitive equipment. Internal medical devices can
move or dislodge in the presence of strong magnets, causing injury to the
user. Persons with pacemakers should exhibit extreme caution when working with
magnets. Other medical devices that can be disabled by magnetic fields include
defibrillators, prosthetic limbs and insulin pumps.
Damage to Electronics and Magnetic Storage Media
Certain electronic devices such as cell phones and pagers are sensitive to
magnetic fields and can be damaged if brought too close to the magnets. Store
magnets in a safe location away from electronic objects. Credit cards and
magnetic personal identification cards can be demagnetized if brought too
close to the magnets.
Protective equipment
In addition to standard personal protection equipment (PPE) requirements,
personnel working with the magnetic mount wheel sensors and mounts should
always wear gloves to reduce the risk of pinching hazard. Protective eye
equipment should also be worn as magnets are fragile and can break if they
come together too quickly. Sharp fragments from the magnets can cause damage
to eyes and skin.

Wheel sensor operation
TRS-SENSOR-DIA /A
The TRS-SENSOR-DIA /A (diaphragm sensor) is a diaphragm-based wheel sensor
supplied by RIMEX Supply Ltd for use in mining and off-the-road (OTR)
applications. The wheel sensor is designed for installation in extreme
environmental conditions with or without liquid tire additive. Figure 1 below
shows the diaphragm sensor.
FIGURE 1 – TRS-SENSOR-DIA /A WHEEL SENSOR (PROTOTYPE SHOWN)
TRS-SENSOR-DRY /A A
The TRS-SENSOR-DRY /A (dry fit sensor) is supplied by RIMEX Supply Ltd. for
use in tires subjected to less extreme environments without the use of liquid
tire additives. The dry fit sensor is also suitable for service vehicles with
smaller rim diameters that require a lower profile lighter sensor. Figure 2
below shows a dry fit sensor.
FIGURE 2 – TRS-SENSOR-DRY /A WHEEL SENSOR (PROTOTYPE SHOWN)
The dry fit sensor is mounted to the barrel of the wheel using the included large diameter clamp. Refer to the Installation section for more information on mounting the dry fit sensor.
Overview
All wheel sensors have two modes of operation; storage and normal. In storage mode, the wheel sensor does not transmit unless induced with a magnet. When induced, the measured pressure, temperature, and diagnostic data are transmitted. In normal mode, the wheel sensor will transmit the measured pressure, temperature, and diagnostic information every minute by default. The wheel sensor will transmit immediately when the measured pressure changes by more than 2psi since the last transmission. Subsequent transmissions will occur every second for every 10psi of change that was measured. These extra transmissions ensure that critical tire data is received by a listening TyreSense device. The microprocessor on the wheel sensor wakes up every second to measure and process pressure, temperature, and diagnostic information. If a transmission is required, the wheel sensor will transmit, otherwise it will re-enter low power mode until the next second interval. The wheel sensor will transition from storage mode to normal mode when the wheel sensor measures 35psi (241kpa) or greater. To re-enter storage mode, the wheel sensor must be induced with a magnet for at least 30 seconds. It is recommended for the wheel sensors to be in storage mode for transport and storage. The wheel sensors are shipped from our production facility in storage mode.
Sensor ID
Each wheel sensor has an engraved six-digit identifier on the plastic cap.
Refer to Figure 3 below for the location of the sensor ID. The ID is composed
of only the following digits and letters, 0 – 9 and A – F. This ID is required
to identify the wheel sensor and program the sensor into a tire position on
the TyreSense Receiver Unit. It is important to record this ID and the
intended tire position prior to installing the sensor in a tire.
FIGURE 3 – SIX-DIGIT SENSOR ID – 01366C
Inducing the wheel sensor
To induce a wheel sensor to transmit, position a strong magnet, such as a
MagMount, on the plastic side of the sensor for a few seconds or slowly swipe
the sensor across a TyreSense Sensor Buddy. If the wheel sensor fails to
transmit, the wheel sensor may need to be removed for a few seconds,
repositioned/rotated, and retried.
Cleaning
All wheel sensors can be cleaned with wet rag or towel. It is not recommended
to submerge or rinse dry fit sensors. Diaphragm sensors can be submerged or
rinsed, but pressure washing is not recommended as permanent damage may
result. It is not recommended to clean the air passage of the dry fit sensor
because it may damage or block the air passage.
Cleaning debris from the holes on the metal cap of the diaphragm sensor should
be done carefully to avoid damage to the diaphragm. Damaged or punctured
diaphragms are not covered under warranty.
Wheel sensor installation
Before installing a wheel sensor, especially ones that have previously been in service, the sensor should be induced and scanned with either Sensor Tracker or Sensor Buddy. Scanning the wheel sensor will determine if the wheel sensor is operational and show the remaining sensor life and battery voltage. Figure 4 below shows a wheel sensor scan using Sensor Buddy. Refer to the TyreSense Client User Guide for more information on Sensor Tracker or Sensor Buddy. It is very important to record the tire position and wheel sensor ID prior to the installation of the wheel sensor. Failure to do so may result in not knowing the wheel sensor ID or tire that the wheel sensor is installed.
FIGURE 4 – SENSOR BUDDY SCAN
During tire inflation, it is recommended to inflate the tire using the
TyreSense IDX or monitor the inflation using Sensor Tracker or TyreSense
Client software. Monitoring the inflation verifies that wheel sensor is
working as expected and the sensor ID being monitored is indeed in the tire
being inflated.
TRS-SENSOR-DIA /A
For installation instructions for the diaphragm sensor, refer to the Magnetic
Mount Install Guide.
TRS-SENSOR-DRY /A
For installation instructions for the diaphragm sensor, refer to the Dry Fit
Install Guide.
Programming
To program the wheel sensor ID into the TyreSense Receiver Unit, refer to the
Display User Guide or TyreSense Client User Guide for more information.
Configuring
After the wheel sensor ID has been programmed into the TyreSense Receiver
Unit, the cold pressure calculation will need to be configured using the
TyreSense Client software. For tires with liquid additive (TRS-SENSOR-DIA /A
only), ensure that the cold pressure calculation is set to “WET”. For tires
without liquid additive inflated with air or nitrogen, ensure that the cold
pressure calculation is set to “DRY/N2”. Figure 4 below shows the cold
pressure calculation option in the TyreSense Client software.
FIGURE 5 – COLD PRESSURE CALCULATION (GENERAL SETTINGS – TYRESENSE
CLIENT)
Final checks
Using the TyreSense Client software, TyreSense IDX, or TyreSense Display,
verify that the pressure displayed for the tire position matches the pressure
reading displayed with a master gauge.
Wheel Sensor Calibration
The wheel sensor is calibrated for operation during production and designed to
be accurate throughout the life of the wheel sensor. No tuning or calibration
is required by the customer
Troubleshooting
Wheel sensor pressure reading do not match the master pressure gauge
- Incorrect sensor ID is being monitored
- Verify sensor ID by checking records
- Verify sensor ID by making a pressure adjustment of ~5psi on the tire
- Faulty or improper master gauge reading
- Check master gauge for accuracy and calibration
- Wheel sensor pressure reading age may be old
- Verify that the TyreSense pressure reading is recent and occurred after tire pressure adjustment has been completed.
- Wheel sensor pressure and master gauge pressure may both be correct
- The allowed pressure difference must be a sum of the measurement errors of both the wheel sensor and master gauge. Example: If the master gauge has an error of 3% and the wheel sensor has an error of 3%, the maximum allowable error is 6%
- Faulty or plugged sensor
Wheel sensor calculated cold reading drifts after inflation
- Wheel sensor has not been provided enough time to temperature soak. It takes quite a few minutes for the wheel sensor to match the contained air temperature of a tire. This is expected behavior after an external pressure adjustment and air exchange.
- Faulty or plugged sensor
Wheel sensor calculated cold reading incorrect
- Wheel sensor has not been provided enough time to temperature soak. It takes quite a few minutes for the wheel sensor to match the contained air temperature of a tire. This is expected behavior after an external pressure adjustment and air exchange.
- Incorrect cold pressure calculation on the Tyre Sense Receiver Unit or Tyre Sense IDX
- Verify the cold pressure calculation using the Tyre Sense IDX or Tyre Sense Client software
- Faulty or plugged sensor
Wheel sensor is not been received by Sensor Tracker or other Tyre Sense devices
- Wheel sensor is in storage mode and not transmitting regularly
- TyreSense listening device is not in range of the wheel sensor
- Check antenna connections on the TyreSense Receiver Unit or TyreSense IDX
- Faulty or plugged sensor
Wheel sensor does not induce
- Weak or improperly placed magnet
- Retry inducing the wheel sensor
- Wheel sensor is in error mode
- Too many attempts at inducing a wheel sensor will result in the wheel sensor entering an error mode and ignoring the magnetic switch. Wait a few minutes and try again.
- Faulty magnetic switch
- The magnetic switch is not required for wheel sensor operation. It is only a diagnostic utility.
Wheel sensor not exiting storage mode
- Incorrect sensor ID is being monitored
- Verify that the correct sensor ID is being monitored
- Pressure within a tire is less than what is required to enter normal mode
- Faulty or plugged wheel sensor
