4 to 20 mA DC Clamp-on Meter Doesn't Break The Loop

Yoko_0830-AYokogawa's CL420 clamp-on process meter safely measures 0-120 mA dc process control signals without breaking the loop. Typical application examples include distributed control systems, programmable logic controllers, pressure and temperature transmitters, and loop powered isolators and indicators. Features of the process meter include 0.2% accuracy and 0.01 mA resolution from 0-20 mA dc, mA measurement and percent of span for 4-20 mA, dual LCD numeric display, and LED torch light. The CL420 is complementary to the company's existing portfolio of calibrators, such as the CA11 loop calibrator, CA71 and CA150 multifunction calibrators, and the CA450 process meter. The analog output can be used as an input to the XL120 data logger, TY500/700 multimeters, or chart recorders. Standard accessories provided with the meter are a carrying case, 4 AA batteries, and an instruction manual. Optional accessories include analog output cables with banana plugs or screw terminals. The CL420 clamp-on process meter is available through the company's distributors at a suggested list price of $625.
