FLT93B BASIC FlexSwitch® - Premium Flow and Temperature Monitoring
Switch
Flow Switch SummaryThe 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.
