SPECIALTY ACCELEROMETERS

In addition to the high performance industrial accelerometers shown on previous pages, a number of special sensors have been

produced in response to customer demand; examples of specialty sensors include the following:

Model 222A Zerkometer: a direct replacement for your bearing's zerk fitting; eliminates the time / cost of bearing pillow spot facing

Model 799LF: a true low frequency accelerometer incorporating a low noise design, high sensitivity at low frequencies, and

built-in filtering ensure unmatched performance and 'true' low frequency measurement

Model 797T-1: this dual output sensor incorporates both temperature measurement as well as vibration in a single sensor package

Model 786T: this low cost dual output sensor incorporates both temperature measurement as well as vibration in a single sensor package

Model PC420D: this two-wire "Displacement" transmitter is the latest addition to Meggitt Sensing Systems

 

(Wilcoxon) two-wire family of vibration transmitters,  The 4-20 mA output is determined by first measuring

the peak to peak vibration, then converting that level to a 4-20 mA signal. Because balance components tend

to dominate the

vibration spectrum when viewed in displacement units, the PC420D sensor is able to track the balance

component of machines, one of the most sought after parameters.Integrating this signal into an existing PLC,

DCS or SCADA system simplifiesreal time health monitoring because vibration, formerly considered too

complex, can now be trended in easily understood units of mils or millimeters of displacement.
