Description
The C437D,E Series 2000 Gas Pressure Switches are pressure-actuated switching devices used in industrial gas system applications for safety shutoff, pressure control, and differential-pressure control. All Series 2000 models have MicroSwitch? snap switches to open or close a circuit on pressure rise or drop.

Features:
  • Use C437 for SPST (non-mercury) switching.
  • Models intended for lockout applications must be manually reset before resuming operation.
  • Models with pressure range of 1 to 26 in. wc (0.25 to 6.5 kPa)compensate for momentary surges in gas pressure with a restrictive orifice in inlet pressure channel.
  • Impede tampering and provide dust-resistant operation with enclosed setting.
  • Increase strength of control diaphragm with Buna N fiber-reinforced material.
  • Two Buna-N fiber-reinforced seal-off diaphragms for added reliability.
  • Clear glass cover allows observation of interior mechanism to aid in setting and checkout.

    Application: Industrial gas system applications for safety shutoff, pressure control, or differential-pressure control.
