This is the PL40 split-type hydrostatic level transmitter from PANASIA, consisting of a submersible stainless steel probe and an external junction box. The probe is submerged in the liquid to calculate the liquid level by measuring the hydrostatic pressure. The junction box is responsible for signal processing, temperature compensation, and signal output, providing a standard 4~20mA industrial signal that can be used with PLC, DCS, or digital display instruments for remote level monitoring and control.
