Self-powered Tach Kits for Easy, Reliable Speed Monitoring


Reduce downtime, maintenance costs and avoid potential prime mover failures

GCS Tachometer Kits take the guesswork out of tracking your turbine or engine speed. GCS self-powered Tachometer Kits provide a safe, reliable means of speed montoring and data logging of turbine and engine peak speeds. The self-powered tachometers do not require external voltage; only a connection to the speed sensor is needed.

Specified for Woodward TG and PG Turbine Governors, GCS self-powered Tach Kits are scalable, field-configurable and easy to install directly on the governor. The tachometers have gear-encased housing and are intrinsically safe - Class I, Div II approved. Avoid potential prime mover failures, reduce downtime, and maintenance costs due to turbine or engine overspeed.

TG Governor Tachometer Kit

GCS TG Tachometer Kit mounts on mechanical-hydraulic Woodward TG governors used on general purpose steam turbines. The self-powered TG Tach Kit provides easy, reliable speed monitoring and data logging.
