    อุปกรณ์วัด Control System (4-20 mA Amperometer, Simulator and Calibrator)

    HI 931002

    4-20 mA Amperometer, Simulator and Calibrator

    HI 931002 is a portable instrument designed by the Plant Repair and Maintenance Operator for the MRO! This portable simulator can monitor and regulate 4-20 mA from practically any process meter with or without a voltage generator. The communication bus from process instrumentation can be simulated in any of the following modes:

    Passive drive/Calibrator mode:
    HI 931002 can set the 4-20 mA current values and the user can then adjust the process meter accordingly.

    Active drive/Simulator mode:
    HI 931002 simulates the correct current values as above in addition to providing power to the bus communication. Power is provided through an external adapter (included) which is connected to the simulator. This mode is ideal to calibrate chart recorders, pressure transducer or current indicators.

    Passive measurement/Tester mode:
    HI 931002 practically becomes an Amperometer. It measures and displays the mA (or pH) values transmitted by the process meter.

    Active measurement/Tester mode:
    Same as above in addition to providing voltage to the 4-20 mA bus.

    HI 931002 can measure incoming current, provide power, and simulate 4-20 mA output to calibrate your process meter. A large LCD shows values on the display. You can select between drive and measurement modes through a switch on the front panel and two dials allow for quick adjustment of the current.
