Pressure Switches and Transmitters

      We offer a wide selection of Pressure switches and transmitters primarily to the chemical, oil and gas, power and nuclear industries

      Pressure Transmitters

      “Set it and forget it” reliability makes SOR pressure transmitters perfect for applications when space is tight. Our stainless steel construction stands up to the rigors of hostile environments and hazardous locations. Available with either 4-20mA or 1-5 VDC outputs and with adjustable ranges for pressure transmitters.

      SOR pressure transmitters are designed for use in hazardous conditions and hostile environments. Their rugged and compact design provides an instrument perfect for use in tough locations where space is limited. The recently introduced 815PT smart pressure transmitter with HART®7 and ModBus® RTU is just one example from the 800 series of how SOR is bringing technology and durability together.

      Pressure Switches

      SOR pressure switches are field-proven, low cost process instruments for use in either primary or redundant pressure applications in a wide variety of industries. Even though the technology is proven by the original Static “O” Ring mechanical switches that set industry standards more than 50 years ago, we continue to expand our product offerings to meet changing industry needs. SOR pressure switches are designed and offered with a number of agency approvals, housing enclosures and switching configurations to meet the demands of global markets. The large selection of product components provides the optimal instrument specifications to handle the toughest of applications.

      When it comes to pressure switches, one size does not fit all. SOR will engineer a pressure switch to meet your individual needs using components such as switching elements, diaphragm systems and pressure ports specifically selected for your application. The Mini-Hermet – explosion proof pressure/compound pressure switch provides the trusted SOR pressure sensing assembly hermetically sealed in an explosion proof steel capsule.

      Known as one of the most flexible products, SOR differential pressure switches are available in weatherproof and explosion proof configurations to best match the application. Most models are safety certified to IEC 61508 (SIL) for non-redundant use.
