Hardware Features
The IWPTL range of Wireless Pressure Transmitters has been designed to measure
the pressure of the medium connected and transmit the value to one of the IWR
range of receivers where the value can be outputted as either a 4-20 mA or 1-5
V dc signal.
The IWR-1 has a single output and the IWR-5 has five outputs, each of which
can be linked to an IWPT transmitter. The IWPT pressure transmitter works on
the license-free
GHz band.
Ranges of up to 500 m are possible using the standard transmitter and receiver
unit with the optional 3dBi antenna giving a range of up to 750 m. The
transmitter is powered by a 3.6V lithium cell and care must be taken to insert
the battery in the correct polarity.
UNPACKING
The instrument should be carefully inspected for signs of damage that may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.
PRODUCT IDENTIFICATION LABEL
The unit delivered should be carefully inspected to ensure it is suitable for
the application required. Detailed information on the product is included in
the identification label and the user manual.
Please ensure in particular, that the pressure range of the IWPTL is suitable
for the intended application and that the IWPT unit will not be subjected to
pressures and/or temperatures greater than those specified in this manual.
INSTALLING/CHANGING THE BATTERY
A Lithium 3.6V battery is included inside the IWPTL transmitter. The battery
may be changed at any time but the correct polarity must be observed at all
times! After the battery has been changed, the pushbutton SW1 should be pushed
for 5s at the same time as the unit is switched on using SW3. This is to
ensure the battery life count is set correctly when a new battery is
installed.
The internal LED will flash 5 times to indicate this procedure has been carried out successfully. The battery life is determined by the rate the transmitter sends the Pressure value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s. Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.
WARNING: MAKE SURE THE CORRECT BATTERY POLARITY IS OBSERVED INCORRECT BATTERIES MAY DAMAGE THE UNIT USE ONLY 3.6V LITHIUM C CELL BATTERIES
Mounting Instructions
Ensure that:-
- The instrument is used on a pressure medium that is compatible with the wetted parts
- The correct seal is used and that the maximum torque (see below) is not exceeded
- Fluid is not allowed to freeze in the pressure port as the diaphragm may be ruptured
- No sharp objects are inserted into the pressure port as the diaphragm may be damaged
Tighten the unit in place using a wrench on the 18mm A/F hexagon provided on the unit. Ensure that no more than 15Nm is applied, that the system is de- pressurized, and that a suitable pressure seal is used.
SETTING UP THE IWPTL WIRELESS PRESSURE TRANSMITTER
The IWPTL instrument is shipped in a default configuration which allows the
unit to connect with any default IWR receiver unit and transmit the measured
pressure every 10s simply by switching the unit on using SW3 on the internal
circuit board.
If a different update rate is required, or a different network frequency channel is required these parameters can be selected using DIP Switch 1 as detailed below:
Switches 1, 2, 3 & 4 select the RF Network the IWPTL will transmit on. The default network for both the IWPT transmitter and IWR receiver is network 1.

The IWPTL transmitter is now set up and ready to be used. Install the unit
into the pipework as required and switch the unit ON using SW3. Pushbutton
switch SW1 can be pushed to force the unit to transmit its current pressure
and LED 1 will flash twice if the transmission has been received and
acknowledged by an IWR receiver unit.
If the unit has transmitted successfully the 4-20 mA or 1-5 V dc output of the
connected receiver unit will output a value reflecting the pressure level
being measured.
