Yokogawa CL420 clamp-on process meter

The Yokogawa CL420 clamp-on process meter from Madison Test & Measurement is used for measuring control signals and process instrumentation.

The device allows the user to make safe current checks of 4-20 mA and 0-120 mA DC process control signals without breaking the loop. In addition, the output function provides a simple way to log and monitor the data. Typical applications include distributed control systems, programmable logic controllers, pressure and temperature transmitters, and loop-powered isolators and indicators.

The product incorporates a range of features: 0.2% accuracy and 0.01 mA resolution from 0-20 mA DC; mA measurement and % of span for 4-20 mA; dual LCD numeric display; LED torch light; data hold function; 6 mm clamp diameter.

An analog output is available, which can be used as an input to the XL120 data logger, TY500/700 multimeters or chart recorders.
