Siemens' SITRANS LH100 pressure transmitter converts hydrostatic pressure into a standardized level-proportional 4 to 20 mA signal. The narrow, compact sensor can be mounted in pipes as small as 1" in diameter, so it fits a wide range of applications. The integral cable includes the signal wires and an atmospheric vent tube for the reference pressure.  The vent tube should be protected by a dessicant cartridge to limit build-up of moisture in the vent tube.  The 316L stainless steel housing and IP68 rating make the LH100 suitable for use in harsh environments. It replaces the retired Siemens SITRANS P MPS submersible level transmitter.

  • Key applications include water supply, drinking water, wastewater, and pressureless/open tanks and wells
  • Available standard ranges: 0 to 9 Ft H2O with standard 33-foot integral PE cable to 0 to 60 Ft H2O with 98-foot integral PE cable; Call for custom cable lengths
  • ±0.3% to ±0.5% full scale accuracy, depending on range
  • Slim design for mounting in pipes with as small as 1" inside diameter
  • Piezo-resistive aluminum oxide ceramic sensor and stainless steel housing make the LH100 immune to harsh environmental conditions
  • Complete LH100 system includes sensor and cable, a junction box, cable hanger, and anchor clamp accessories to simplify installation
  • Available with drinking water, UL, ATEX, and IECEx approvals
