Continuous Level Transmitter- Series CRF
Loop-Powered, 4-20 mA Output, RF Admittance Technology
Continuously monitor the levelof liquids and slurries, without worry of false signals as a result of material build-up. Loop powered Series CRF delivers a 4-20 mA isolated output signal proportional to the height of material in a tank or holding vessel. Continuous level transmitter can be field calibrated to fit your specific application. Integral electronics and two-wire design simplify installation. Probes should be mounted vertically and are easily trimmed to shorter lengths where required. When mounting in nonmetallic or horizontal tanks, a separate grounding rod must be used. Consult factory regarding mounting flange and grounding rod assemblies.
