AMS releases Westcon AC tachometers for diesel engine rotational speed measurements

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

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.
