Thermal point level switch for the detection of level in all vessels.
Wide operating temperature range -100° F to +850° F (-70° C to +458° C).
Switch on level change of .03 inch without concern for changing temperature, density, dielectric constant or chemical composition.
Removable, plug in electronics.
Free of all moving parts that can stick coat or fail.
Fast response time of .1 to 1 second on wetting, media dependent.
Self heating sensor design improves repeatability. No separate heater to fail or slow response time.
Two Year Workmanship Warranty.
