The KAL-K thermal flow switch and KAL-A thermal flow sensor utilize KOBOLD’s revolutionary, temperature compensating electronics. These compact, one-piece units provide reliable readings unaffected by temperature or physical characteristics of a wide variety of process liquids. This breakthrough is made possible through the use of state-of-the-art microprocessor technology. The microprocessor can be field calibrated to the users’ liquid properties and operating range in a simple, five minute set-up procedure. This intelligence, coupled with a “no moving parts” design, make the KAL a superior performer in virtually all applications. To further enhance the versatility of the KAL-K and KAL-A, both are offered in a 3-A compliant and an explosion roof version. The KAL-K incorporates an 8 segment bar-graph LED flow trend indicator and one flow alarm setpoint. The setpoint is fully configurable as NPN, PNP, normallyopen or normally-closed. The KAL-A applies the KAL’s advanced microprocessor based technology to the problem of rate detection. It incorporates a 4-20 mA, flow rate proportional output, the same 8-segment LED display found in the KAL-K, and an optional PNP setpoint alarm relay.
