The FLT93F insertion type FlexSwitch for liquid point level or interface detection and temperature monitoring. It represents the first true technological breakthrough in thermal technology in over a decade. This product was designed for heavy industrial environments including high temperature and high pressure. FCI is the only thermal manufacturer providing temperature compensation to ensure set point accuracy for process temperatures that vary up to ± 100° F.
The FLT93F offers very fast response time to level trip points and is suitable for small process connections. This product is easily field-configured or factory preset, providing unparalleled flexibility, accuracy and stability for all multiple process sensing and switching requirements.
For Level/Interface Service: Accuracy: ± 0.1 inch [± 2.5 mm] Repeatability: ± 0.05 inch [± 1.3 mm]
For Temperature Service: Accuracy: ± 2° F [± 1° C] Repeatability: ± 1° F [± 0.6° C]
