Instrotech has signed up with Monitran to market the British manufacturer's range of accelerometers and portable vibration sensors. Released this year, the g-mac accelerometer signal conditioning module (MTN/8066) is designed for monitoring gears and bearings to provide early indication of wear.
Monitran’s g-mac accelerometer signal conditioning module
This versatile, cost-effective alternative to traditional vibration monitoring instrumentation features signal conditioning and filtering circuitry for identifying the small amplitude, high-frequency elements - present within most machinery vibrations - that provide the earliest indication of wear in, for example, bearings and gears.
The g-mac can also be used as a versatile and low-cost general-purpose accelerometer signal conditioning unit. Moreover, it can be integrated into wired and wireless networks to facilitate the remote monitoring of vibrations in a wide range of industrial applications.
Bob Pickard, Monitran's technical director, comments: "Normally the tell-tale vibrations associated with mechanical wear and tear are hidden within the overall noise of the machine. The g-mac module, in conditioning these small amplitude, high frequency vibrations, can therefore play a crucial role in predictive maintenance."
The g-mac module is in a standard DIN format for rail mounting, can accept any standard two-wire accelerometer, and provides three different outputs. These outputs are: a bespoke acceleration signal (proportional to 4-20 mA or 0-10 V d.c.); an ISO 10816-3 overall root mean squared (RMS) velocity signal (also proportional to 4-20 mA or 0-10 V d.c.); and the raw, alternating current (AC) generated by the accelerometer.
