Field Instrumentation - Monitoring and Control

Fisher® field mounted instruments provide monitoring and control to final control devices. Transducers, controllers, volume boosters, solenoids and switches are used to monitor and control flow, temperature, pressure and level variables in the process industry. These instruments complement the control valves to provide the necessary information to the operators to control the process.

Level Switches
On-off switch that senses high or low liquid levels. A displacer is used as the sensor and is located in an external cage that mounts to the outside of a vessel.
