LIQUID AND OIL LEVEL PROBES

The function of a Liquid Level Probe is to measure and display

refrigerant or oil level in a vessel.

Applications

Henry Technologies' Liquid Level Probes are designed for use in a variety of

refrigeration and air conditioning applications. The Liquid Level Probes use

a 1-1/4”-12 Rotalock fitting to mount to Liquid Receivers or Oil Reservoirs

and provide a 0-5V output of fluid level. Probes are custom ordered based

on specific application and desired features.

Henry Technologies' Liquid Level Probes are suitable for use with HFC and

HCFC refrigerants, as well as their associated oils. Each Probe should be

ordered based on specific application to ensure proper calibration.

aluminum. The Rotalock connection is made of plated steel, and the probe

head is cast aluminum.

How it Works

The Liquid Level Probe measures refrigerant or oil level by sensing a change

in capacitance between the LLP probe rod and the receiver/reservoir wall.

As the fluid changes in level, the output voltage changes between 0 and 5

volts. For example, at the 0% set level the output would read 0V, at the 50%

set level the output would read 2.5V, and at the 100% mark (Typically set at

90% of vessel capacity) the output would read 5V. All Liquid Level Probes

come factory calibrated based on the order specification but are easily

recalibrated in the field if needed.

Installation - Notes

1. Liquid Level Probes are factory calibrated based on order

specifications.

2. Re-calibration procedure and wiring diagrams are included with the full

instructions given in the Product Instruction Sheet, included with each

unit.
