OCLC-HH-B

Freedom from TB wire disturbance




The Online Current Loop Calibrator- Hand Held - Basic (OCLC-HH-B) is a lightweight, portable, handheld current generator for loop current sensing instruments testing and calibration.

 

 

bullet

It generates current signal (mA) for instruments calibration and testing.

bullet

It is built around patented technology developed at BARC, Mumbai.

bullet

It's patented; unique current generation technique dynamically isolates the actual transmitter loop current and presents user set current to the loop sensing instruments. Thereby allowing online testing of the instruments.

Advantages

bullet

No need to isolate the measuring instrument for the test/calibration.

bullet

The instrument wiring is not disturbed.

bullet

Transmitter loop current is unaffected.

bullet

Other instruments sensing the same loop current are also unaffected.
