Low Range – Hermetically Sealed Differential Pressure Switch


Designed primarily for low pressure clean air and gas applications, the hermetically sealed low range differential pressure switch accurately reads very low pressures in hazardous areas requiring protection. The 107EL uses a diaphragm with a large sensing area and is the ideal choice for pressurized room (clean room) applications because it measures the difference between one room and another (air ducts) and lets you know if a air filter is clogged. External set point adjustment with visual indication is standard, allowing simplified switch calibration.

  • Hermetically sealed pressure switches
  • Varies from 0 to 40 in wcd
  • Setpoint adjustment without declassifying the hazardous area
  • SPDT or DPDT switching element
