Process Multimeter CA450 – Yokogawa
The Yokogawa CA450 integrates the functionality of a loop calibrator with a digital multimeter. The CA450 Process Multimeter is a portable test instrument to combine a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one tool. The CA450 provides 24-Volt loop power, reducing the need for carrying a separate power supply when performing transmitter testing. And with its built-in, selectable 250-Ohm Hart resistor, it also eliminates the need for a separate resistor. Process technicians can now do the same job while carrying less equipment.
Loop Power and 4 to 20 mA Output function in a DMM. From daily inspection to troubleshooting of measurement instruments—all in a single unit!
