AMS Instrumentation and Calibration announces the release of industrial AC tachometers by Marsh Bellofram Corporation, a member of the Bellofram Group of Companies.

The new Westcon Model 758-9905000 is an industrial AC tachometer generator, designed for high-reliability 24/7 jet and diesel engine rotational speed measurements within voltage responsive systems.

Designed to convert rotational shaft speed inputs into linear analogue voltage outputs, even in the harshest of environments, Westcon 758 Series AC tachometers have an approximate starting torque of 2.0 in-oz, which is maintained at running speeds of up to 1000 RPM. Their rugged construction incorporates a multi-pole cylindrical magnet, which turns within a wound stator constructed from high-quality transformer iron lamination material. 

Built to deliver high performance in harsh environments, the tachometers are housed within a dustproof aluminium alloy housing and feature an SAE 1/8” type steel mounting with 3/16” solid drive dog.

Key features of Westcon 758 Series AC tachometers also include single phase output current expressed as a sine wave over the full speed range of the tachometer; 100 ohm stators provided as standard; two binding posters available for electrical connection; and custom stator ranges supplied on request.

Backed by more than 20 years of successful market pedigree, Westcon rugged AC tachometers support GE turbofan engines on the McDonnell Douglas F/A-18 Hornet twin-engine combat jets where they have been successfully performing ongoing, reliable RPM measurements. 

The AC tachometers have also supported numerous military and off-highway vehicle diesel and gas engine applications, particularly where a standard SAE screw-type tachometer is necessary.
