capacitive level transmitter

series crf2 capacitive level transmitter

powder, bulk or liquids, no-moving parts, excellent chemical resistance

the series crf2 is a level transmitter providing a two-wire 4 to 20 ma output to indicate level of liquids, powders and bulk materials. State of the art sensing technology in the crf2, using impulse rf admittance measurement provides excellent accuracy and stability. The crf2 senses capacitance changes resulting from the height of the material in the tank between the probe and the tank wall. In non-metallic tanks or tanks that do not have the wall parallel to the probe a ground reference must be used.

the crf2 comes with either a rigid or flexible probe depending on application installation need and probe length required. Featured in the crf2 is easy push button calibration of zero and span. Custom order the crf2 to any length probe that you need for your application. Fep covered probe is ideal for use with corrosive media. This technology also provides immunity to external rf sources like walkie-talkies and cell phones as well as minimal interference with radio communication or other electronic systems.

conductivity level probe

series clp conductivity level probe

low cost, compact design

series clp conductivity level probes are used to determine the presence of a conductive liquid at a set level by sensing conductivity. The series clp is coupled with the series tswb temperature level controller for a complete level control system. These probes allow for the measurement of conductivity between the probe fitting and end, which is isolated by a ceramic insulator, or between the probe ends of two probes. The clp can be mounted in any orientation in a tank, tee fitting, or any compatible threaded port. The probe end is solid stainless steel allowing substantial resistance to heat and corrosion.

product applications

• water level monitoring
• tank level control
