103 HPT

The 103 HPT Immersion/Submersible Probe includes a measuring cell, two-wire transmitters, and a specialized capillary cable. Housed in stainless steel, the probe features a pressure-sensitive diaphragm protected by a plastic cap. The level signal is determined by the pressure difference between the water column above the probe and atmospheric pressure, transmitted through the capillary tube. This differential pressure is converted into a 4-20 mA analog signal by the measuring cell and electronics, with HART communication also available.
