Moving Coil Ammeters & Voltmetrs
DESCRIPTION

Moving Coil Instruments are protected from damage or breakage under adverse conditions due to spring loaded jewel & pivot system. These Instruments are free from external magnetic field influences because of centre magnet system and are "CE" certified.
Voltmeters are made upto 600V for direct connection and upto 1200V with / without 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 ¢ (p, etc. can be supplied on request.

Ammeters with internal shunts are available upto 30 Amps and for higher currents upto 12000 Amps use external shunts of 50mV, 60mV, 75mV etc. (Please refer data sheet no. Shunt 03/99.)
