Yokogawa CL420 4mA to 20mA Clamp-On Process Meter for DC mA

Yokogawa CL420 4mA to 20mA Clamp-On Process Meter for DC mA

The Yokogawa CL420 allows the user to make safe current checks of 4 to 20mA without breaking the loop. In addition, the output function provides a simple way to log and monitor the data.

The CL420 Clamp-on Process Meter will safely measure 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.
