The FLT93B BASIC insertion type FlexSwitch for flow and temperature monitoring represents the first true technological breakthrough in thermal technology in over a decade. FCI is the only thermal manufacturer providing temperature compensation to ensure set point accuracy for process temperatures that vary up to ±100°F. The FLT93B is easily field-configured, providing unparalleled flexibility, accuracy and stability for all multiple process sensing and switching requirements.
The FLT93B BASIC flow switch is available with all of the below listed standard features for a very attractive price and with quick delivery as soon as 2 business days ARO.
- Pump protection
- Cooling water/heat exchangers
- Drain line flow
- Safety spray nozzle monitoring
- Oil well system testing
- Relief valve monitoring
