Level Transducer Probes


The level transducer probes (LP) are made for monitoring refrigerant level in vertical or horizontal receivers. The probe operates with capacitance to provide a continuous level reading. The electronic circuit provides an analog signal that is proportional to the refrigerant level. This signal is provided as a 0-5 vdc output. This signal is commonly used with supermarket rack controllers, PLCs and other types of controlling devices that will accept the 0-5 vdc output.

The probe is threaded directly into the receiver by the use of a 3/4" NPT coupling or roto lock. The probe has no moving parts and used 24 vdc as the input voltage
