Product Items

IMCL Low Cost Submersible Pressure Sensor

Economical IP68 protected sensor with stainless steel 316L housing and Ceramic strain gauge sensing diaphragm for measuring liquid depth pressure or the pressure in a submerged pipe or vessel. Measure hydrostatic pressure from from 0 to 10 mWC (33 ftWC) up to 0 to 100 mWC (330 ftWc) and convert reading to a millivolt, current or voltage signal output. The Ceramic diaphragm has a high chemical resistance to media such as leachate and seawater, and the housing can be upgraded to Duplex stainless steel if necessary for extra material protection. A PUR coated cable is fitted as standard, but for additional chemical protection an FEP coated cable can be supplied.

IMCL Submersible Absolute Reference Depth Sensor

Absolute referenced hydrostatic depth sensor with an IP68 sealed electrical interface, stainless steel 316L, Duplex or PVC housing and a mV, amplified voltage or current output. Available in depth ranges from 1 to 10 bar absolute.

IMCTL Submersible Liquid level and Temperature Transmitter

IP68 combined liquid level and temperature, dual 4 to 20 milliamp output pressure sensor with a 316L or Duplex stainless steel housing and a high corrosion resistant ceramic sensing diaphragm. The IMCTL is available with ranges starting from 10 mWC (33 ftWC) to a maximum range of 100 mWC (330 ftWc) and can measure temperature over a choice of four different scaled ranges between -20 to +60 degC.

IMSL IP68 Stainless Steel 316L Hydrostatic Pressure Sensor

Water resistant pressure sensor for measuring hydrostatic pressures in the range of 0-0.5 mWC up to 0-100 mWC. An all stainless steel 316L construction with Viton O rings seals and a choice of PUR, PVC or FEP vented cabling. The IMSL is used for measuring groundwater, aquifer, reservoir and borehole water level. The internal silicon strain gauge sensor provides a stable water level reading accurate to 0.1% of span linearity with low hysteresis and repeatability errors.

IMSTL IP68 Water Temperature and Depth Transmitter

Stainless steel 316L waterproof probe for measuring both water temperature and depth and generating two separate 4-20mA current loop measurement signals. Select temperature measurement ranges from -20 to +60 deg C and depth ranges of 0-0.5mWG to 0-100mWG.
