PR233 Series Portable Process Calibrator

PR233 series portable process calibrator has simultaneous measurement and analog voltage, resistance, current, thermocouple, thermal resistance, frequency, switching and other signals

The function. Compared with the PR231 series multi-function calibrator, the PR233 series products are very simple in function and operation. They are compact in design and easy to carry, which is very suitable for field applications.

Product features

1.The analog resistor/thermal resistor function is highly adaptable and can be a circular chart recorder.

2.A secondary instrument such as a balance recorder provides a stable signal.

3.The measurement and output functions are isolated from each other and can be used simultaneously.

Industrial-grade resistive touch screen + mechanical button human-computer interaction operation, can Intuitive and convenient setup via touch screen, or mechanical press The keys perform common operations.

4.The resistance measurement function can select three-wire, three-wire and four-wire resistance measurement methods.

5.Built-in high-precision reference temperature compensation and thermocouple quick interface (PR23C does not have this function)

6.Recording function, can realize on-site paperless recording

7.Built-in isolated 24V power supply for easy verification of temperature transmitters

What is process calibration

Process industries are those in which the final product, once manufactured, can’t be separated into its individual components. Examples include the pharmaceutical, petrochemical, electrical power, and semi-conductor industries. Calibrations performed within these industries may happen on a bench in a calibration laboratory; they can also happen out in the plant or in the field. We refer to both bench and field calibration practices that happen within process industries as “process calibration.”

Application

Process calibration professionals can include metrologists, instrumentation and control (I&C) or electrical and instrumentation technicians, electrical technicians, or engineers. Some of these professionals work in a metrology lab. Others work in an instrument shop, and still others work out on the plant floor.
