Submersible Level Transmitter
Pokcenser high accuracy submersible Level Sensor also called hydrostatic pressure level sensor with an enclosure of 27mm, 19mm and 16mm in diameter makes it ideal for level monitoring instruments in well, borehole and tanks applications. Constructed for years of trouble free service, it applies imported 316L stainless steel isolation diaphragm diffusion silicon pressure sensor core and 316L SS body&nose cap as robust. Precision ±0.10%, ±0.25% or ±0.50% of full scale accuracy output. Lightning and surge protection is included to stand up in harsh applications. Special cable for air-venting conduit with a maintenance-free filter preventing particulate or water droplets from entering the transmitter, ensures water tightness, and ventilation between inside and outside, so as to acquire accurate and stable measuring data.
