The Murphy 130-250F Mechanical Temperature Swichgage 2.5" with 8 Ft Capillary and Snap-Acting Switch A25TE-EL-250-8-1/2 is a diaphragm-actuated, temperature-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. This vapor actuated gauge features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against a diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading. This explosion-proof less case A25TE-EL-250-8-1/2 also features an internal SPDT snap-switch, instead of the single pole/pointer contact(s). When the switch closes on rising temperature, it becomes Set. As temperature decreases the switch Resets.

The gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are isolated from ground. They have self-cleaning motion to enhance electrical continuity. Applications for A25 series temperature swichgage instruments include: engines and equipment in oil field, marine, irrigation, construction and trucking industries. Monitoring engine coolant temperature, crankcase oil and transmission oil.

  • 2-1/2 inch/64 mm dial
  • Indicating Gage and Limit Switch
  • Switch Can Activate Alarms and/or Shut Down Equipment
  • Contact(s) Isolated From Ground
  • Internal Snap-Acting SPDT Switch
  • EL = Explosion-Proof Less Case
