STATIONARY STRIKER SENSORY ASSEMBLY
The Exline Stationary Striker Sensor Assembly is used primarily in a Thermowell or directly in a surface application, as in a valve flange or packing case.

The sensor is designed to operate in specific areas where it is not practical to utilize the brass Stationary Sensor. The Stationary Striker Sensor Assembly is made of stainless steel to allow positive service in highly corrosive environments. The fuse-metal material is totally isolated from the pneumatic or hydraulic control media to prevent possible contamination.

The Stationary Striker Sensor Assembly contains a temperature sensitive fuse-metal collar which holds a spring-loaded plunger in position. The collar is made of specific quantities of special metal alloys which melt at a predetermined temperature. The vent valve assembly is mounted directly to the sensor and is connected to the control media via tubing.

At the predetermined temperature the fuse-metal collar melts and the spring-loaded plunger is released. The plunger makes contact with the vent valve, creating a pressure drop in the pneumatic control system. This pressure drop can be used to shut down the equipment or sound an alarm.

The fuse-metal collar is the only required replacement when temperature activated and can be economically and quickly replaced at our factory.
