The Wilcoxon Sensing Technologies PC420A-EX series vibration transmitter is explosion-proof certified for use in hazardous locations. 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-EX is constructed with 303 stainless steel and is corrosion-resistant. It features a 3/8-24 x 3/8 depth tapped hole, SF20-2 mounting stud (included), and 13-foot 18 AWG output leads. The PC420A-EX is manufactured in an ISO 9001 facility.
