The Wilcoxon PC420A-EX series explosion-proof vibration transmitter is certified for use in hazardous locations, providing reliable 4-20mA output proportional to acceleration vibration. This enables continuous trending of overall machine vibration, allowing comparison against standard vibration guides, alerting users to changing conditions, and guiding maintenance prioritization. Available with RMS, peak equivalent, or true peak output options to match specific application requirements.

Constructed with corrosion-resistant 303 stainless steel, the PC420A-EX features a 3/8-24 mounting thread, included SF20-2 mounting stud, and 13-foot 18 AWG output leads. Each unit is manufactured in an ISO 9001 facility.
