The FLT93C insertion and inline type FlexSwitches are designed specifically for liquid point level detection and temperature alarm in sanitary process applications. It's 20 Ra finish makes it suitable for use in food, beverage, pharmaceutical and other clean processes. FCI is the only thermal manufacturer providing temperature compensation to ensure set point accuracy for process temperatures that vary up to ± 100° F. The FLT93C is easily field-configured or factory preset, providing unparalleled flexibility, accuracy and stability for all multiple process sensing and switching requirements.
