Introduction

The UHF submersible pressure transmitter uses diffused silicon sensing for stable hydrostatic level testing, ideal for tank, wastewater and petrochemical liquid measurement.
Three probe styles for diversified depth demands: Cable (0~200m), Solid Rod (0~4m), Stainless Steel Armored Rod (0~15m). Selectable ±0.2%FS / ±0.5%FS precision; standard 4-20mA two-wire output with optional HART/Modbus RS485. Wide 12~36VDC input and up to 600Ω load fit complicated field wiring.
IP65 cast aluminum housing supports -20℃~80℃ ambient work. Optional 304/316L wetted parts, multiple electrical ports, flange/bracket installation, explosion-proof structure and on-site display, all customizable per project needs.

It calculates liquid level by hydrostatic pressure: P=ρgh. The sensing diaphragm converts pressure into 4-20mA, HART or Modbus output, with readings unaffected by tank shape and only related to liquid height and density.We tailor range and configuration to your working medium.
