YOKOGAWA CA450 electronic multimeter collects signals

Producer: YOKOGAWA

The Yokogawa Process Multimeter CA450 is a portable tester that combines a digital RMS multimeter and a loop calibrator, allowing process technicians to efficiently perform their tasks with a single tool. The Yokogawa CA450 provides 24 Volt loop power, eliminating the need to carry a separate power supply when performing transmitter testing. And with a built-in selectable 250 Ohm Hart resistor, the device also eliminates the need for a separate resistor.

Process Multimeter

Model: CA450

The Yokogawa Process Multimeter CA450 is a portable test instrument that combines a digital RMS multimeter and a loop calibrator, allowing process technicians to efficiently perform their tasks using a single tool.

The Yokogawa 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.

Technicians involved in industrial process maintenance must troubleshoot a variety of instrumentation in the field. This requires carrying a wide variety of tools and electrical equipment such as digital multimeters and calibrators/sorucing devices. Individual, single purpose devices may not have the varied functionality needed for equipment validation, in addition to being cumbersome and inefficient to carry. In these situations, a device that can source, measure, and has PC compatibility would be the perfect instrument for the task. The CA450 Process Calibrator is defined by:

Varied Functionality

Source commonly used field instrumentation standards such as loop power, and milliamps DC
Measure like a DMM; capture and log current, voltage, resistance, and even DCS power
Step/Sweep outputs for enhanced testing of field equipment
PC communication for traferring and saving data
