Description :
Moving coil Instruments are protected from damage or breackage under adverse conditions due to spring loaded jewel & pivot system. These instruments are free from external magnetic field influences because of centre magnet system & are “CE” certified. Voltmeters are made up to 600V for direct connection and up to 1200V with external multiplier with sensitivity 1000 ohms/V. Higher sensitivities are available. Scale printed for other variables viz. Speed, Temp, pH, kW, kVAR, Hz or cos ø etc. can be supplied on request. Ammeters with internal shunts are available upto 30 Amps and for higher currents up to 12000 Amps use external shunts of 50mV, 60mV, 75mV etc.
Features :
