Product Information
CompactPro Capacitance Sensor
The CompactPro Capacitance Sensor is a device designed to detect the presence or absence of material in a vessel. It is commonly used in industrial applications to monitor and control the level of liquids or solids in tanks or containers. The sensor operates based on the principle of capacitance, where changes in the electrical properties of the probe are used to determine the level ofmaterial.
Specifications:
- Operating Voltage: 115 VAC
- Mounting: 1 NPS
- Grounding: Earth ground reference conductor integrated within the probe
- Recommended Wire Size: 18 or 16 AWG
Installation
Location and Mounting
The CompactPro Capacitance Sensor should be installed in a location that is
out of direct flow of material. It is recommended
to mount the sensor using a 1 NPS (National Pipe Straight) fitting. If
installing in areas where moisture or moist air could enter the enclosure
through the electrical conduit, it is important to adequately seal the conduit
opening with a duct seal compound.
Grounding
An equipment grounding connection (earth ground) must be supplied to the unit for safety and proper operation. The CompactPro uses earth ground as a reference for calibration and detecting a covered or uncovered condition. The probe includes a ground reference conductor, allowing it to be used in non- metallic vessels. However, installation in a grounded metallic vessel may provide enhanced sensitivity.
Input Power and Field Wiring
The CompactPro operates from a 115 VAC power supply. Field wiring should
conform to all national and local electrical codes.
he terminals for the input power are labeled on the circuit board: L for the
hot wire, N for the neutral wire, and G for the safety ground wire. It is
recommended to use 18 or 16 AWG wire for the installation. The terminals are
unpluggable for easier wiring. To unplug them, hold down on the circuit board
transformer while pulling up on the terminals.
Fail-Safe Selection
Description
Fail-Safe refers to the relay contact positions that are set up to ensure safety in case of a power failure. In the CompactPro Capacitance Sensor, the fail-safe mode determines how the relay contacts behave when the probe is covered or uncovered.
Fail-Safe High
In Fail-Safe High mode, the relay will be energized when the probe is uncovered and de-energize when the probe is covered. In the event of a power failure, the relay contacts will indicate that the probe is covered.
Fail-Safe Low
In Fail-Safe Low mode, the relay will be de-energized when the probe is uncovered and energize when the probe is covered. In case of a power failure, the relay contacts will indicate that the probe is uncovered.
Calibration
Calibration Verification
After calibrating the CompactPro Capacitance Sensor, it is important to verify the sensitivity setting by checking if the sensor senses a covered probe condition with your material.
Calibration Procedure
Note: Ensure that the probe is uncovered and the material is at least 2 feet away from the probe before starting the calibration procedure.
- If the COVERED indicator light is OFF, turn the CALIBRATE
- control counter clockwise (CCW) until the indicator turns ON.
- If the COVERED indicator is ON, proceed with step 2.
- Turn the CALIBRATE control slowly clockwise (CW) until the COVERED indicator just turns OFF.
- Continue turning the control clockwise (CW) to the desired sensitivity setting.
FAQ
Q: What is the operating voltage of the CompactPro Capacitance Sensor?
A: The CompactPro operates from a 115 VAC power supply.
Q: Can the CompactPro be used in non-metallic vessels?
A: Yes, the CompactPro includes a ground reference conductor that allows
operation in non-metallic vessels. However, installation in a grounded
metallic vessel may provide enhanced
sensitivity.
Q: How should I verify the calibration of the sensor?
A: After calibrating, check that the CompactPro senses a covered probe condition with your material.

INSTALLATION
-
Location and Mounting
The probe should be located out of the direct flow of material. The CompactPro is designed to mount utilizing a 1” NPS. When installing the COMPACT PRO in locations where moisture or moist air could enter the enclosure through the electrical conduit, the conduit opening should be adequately sealed with a duct seal compound -
Grounding
An equipment grounding connection (earth ground) must be supplied to the unit for safety and to insure proper operation of the unit. The CompactPro uses earth ground as a reference for calibration and detecting a covered or uncovered condition. A ground reference conductor is integrated within the probe allowing operation of the unit in nonmetallic vessels. Installation in a grounded metallic vessel will in some cases provide enhanced sensitivity. -
Input Power and Field Wiring
The CompactPro operates from 115 VAC. Field wiring should conform to all national and local electrical codes. Terminals for the input power are labeled on the circuit board; L for the 115 volt hot wire, N for the neutral wire, and G for the safety ground wire. Recommended wire size is 18 or 16 AWG. Note: The terminals are unpluggable to facilitate wiring. Hold down on the circuit board transformer when pulling up on the terminals to unplug them.
FAIL-SAFE SELECTION -
Description
Fail-Safe means that the relay contact positions are set up so that in the event of a power failure the relay will de-energize to a condition that is deemed safe for the application. -
Fail-Safe High
Fail-Safe High means that the relay will be energized when the probe is uncovered and will de-energize when the probe is covered. In this mode, a power failure will cause the relay contacts to indicate that the probe is covered
Fail-Safe Low
Fail-Safe Low means that the relay will be de-energized when the probe is
uncovered and will energize when the probe is covered. In this mode, a power
failure will cause the relay contacts to indicate that the probe is uncovered.
CALIBRATION
A multiturn CALIBRATE control is used to compensate for the capacitance of the
empty vessel and to set up the
desired sensitivity. A tool for adjusting the control is provided on the
inside of the lid of the CompactPro. When finished,
return the tool to its clip in the lid for future use.
Calibration Verification
Following calibration, the sensitivity setting that you have set in should be
checked by verifying that the CompactPro senses a covered probe condition with
your material.
Calibration Procedure
(Probe must be uncovered, material at least 2 feet away from probe)
- .If the COVERED indicator light is OFF, turn the CALIBRATE control counter clockwise (CCW) until the indicator turnsON. If the COVERED indicator is ON proceed with step 2.
- Turn the CALIBRATE control slowly clockwise (CW) to the point where the COVERED indicator just turns OFF. Now continue to turn the control clockwise (CW) to the desired sensitivity setting
Material Dielectric Constant
- HIGH sensitivity: 1/8 to 1/2 turn 3 or less
- MEDIUM sensitivity: 1/2 to 1 turn 3 to 6
- LOW sensitivity: 1 turn or more 6 or more
RELAY TIME DELAY
The CompactPro has a single turn control for adjusting the time delay from
approximately 1 to 30 seconds. This is a
time delay for the output relay to change states after a covered or uncovered
condition is sensed. The COVERED indicator
light will immediately respond to a change in covered or uncovered condition
regardless of the time delay setting.
Minimum time delay, 1 second, DELAY control full counter clockwise, CCW.
Maximum time delay, 30 seconds, DELAY control full clockwise, CW.
