The Wilcoxon Sensing Technologies PC420A-IS series vibration transmitter is certified intrinsically safe for use in hazardous areas. It provides a 4-20mA output proportional to acceleration vibration, allowing for continuous trending of overall machine vibration. This trend data can easily be compared against standard vibration guides, can alert users to changing machine conditions, and can help guide maintenance in prioritizing the need for service. The choice of RMS, peak equivalent, or true peak output allows the user to choose the sensor that best fits their requirements. The PC420A-IS is easily integrated into existing process control systems.

The PC420A-IS is constructed with 316L stainless steel and is corrosion-resistant. It features a 1/4-28 tapped hole for mounting and has a 2-pin MIL-C-5015 style output connector and an R6 type mating connector. The PC420A-IS is manufactured in an ISO 9001 facility.
