4-20mA Current Simulator Calibrator Tester Panel Mount


BRT 420GHM High accuracy 4-20mA Current Simulator Calibrator is a kind of constant current source 4-20ma controlling signal calibrator module with panel mounted shell. It has standard 5135 meter case, easy to be integrated for developers. The output range of that calibrator is 3.3mA to 21mA, and its output can be adjusted by two high accuracy potentiometer knobs, one is for rough adjustment and another is for fine adjustment with small changing steps. Its power supply is 7-30V wide range, user can use 9V, 12V, 24V power supply to drive it. With steady reliable accuracy current output, it becomes an essential perfect simplified calibration kits for technicians.



BRT 420GHM High accuracy 4-20mA Current Simulator Calibrator Tester outputs standard constant current source controlling signal, and its 4-20ma current signal output displays in high resolution LED exactly, output accuracy is 0.1mA. Inside the panel mount current simulator tester, there are various types of protection and conversion circuit to ensure that the signal output is steady and reliable. BRT 420GHM analog current simulator calibrator is widely used in frequency converter controlling, PLC adjustment, valve adjustment, meters testing, analog 4-20ma transmitter output simulation, signal source generation, etc. With LED meter panel mounted shell, it is easy to be embedded into equipment in prototype design and do calibration test in industrial site.
