DC Transmitters manufactured to MOD standards 

A tachometer Transmitter (Tachogenerator) connected to a Receiver (Tacho Indicator) makes a Tachometer System for the measurement, monitoring and control of speed.

‘Record’ style permanent magnet self exciting transmitters are AC or DC generators which, when mechanically driven, produce an output voltage proportional to speed.


Combined accuracy is 15% of full scale indication tested at 20°C+-5°C. For temperature range 0 - 35 °C the above accuracy, is doubled.
