THERMOWELL
The Thermowell is a stainless steel unit, used in conjunction with the Exline Stationary Sensor, Exline Stationary Striker Sensor, or Exline Exhaust Gas Temperature Sensor.

The Thermowell unit houses the fuse-metal end of the device, adapting it to be used where the temperature of oil, water, gas, or other element is to be monitored. Typical applications are fuel gas headers, oil sumps, water systems, and natural gas headers.

The Thermowell is designed for use in pressures not to exceed 3000 psi maximum.

Details of Installation
Use 3/4" or 1/2" coupling*. Weld to header or piping. Drill hole in header after coupling has been installed. Care should be used in drilling 1/2" to prevent thread damage.

When installing Exline Stationary Sensor, Exline Stationary Striker Sensor, or Exline Exhaust Gas Temperature Sensor in Thermowell, refer to the “Details of Installation” section of each individual sensor instruction sheet. Use no sealants on Stationary Striker Sensor, Exhaust Gas Temperature Sensor, or Stationary Sensor probe end external pipe thread.

*Dependent on male pipe thread ordered.
