RTD PT 100 Sensor with Head & Terminal

RTD PT 100 Sensor with Head & Terminal

This rugged design offers a variety of protection heads with 1/2″ NPT mounting threads and 304SS sheath. Note that the final length dimension is reduced by 1/2″ so if used in a thermowell the sensor will not bottom and cause damage to the sensor. The standard probe uses a Style 2 (3-wire) lead configuration, but other configurations are available. All probes include a screw terminal block for easy connection of copper extension wire.


  • Longer service life
  • Easy to replace
  • Efficient performance
