Precision Digital manufactures a wide range of rugged meters and controllers designed for quick and easy display of a variety of process signals in harsh or hazardous areas. These signals include 4-20 mA, 0-10 V, strain gauge, pulse, thermocouple and RTD. Our hazardous-area instruments are approved by FM, CSA, ATEX, and IECEx as explosion-proof, intrinsically safe, and nonincendive. Many of our explosion-proof models feature SafeTouch® through-glass buttons which ensure safe operation without the need to remove the cover. Intrinsically safe, loop-powered instruments derive their operating power from the 4-20 mA current loop with a relatively low voltage drop, preventing the need to run additional, costly power lines into the hazardous area. See our side-by-side guide below to learn more about our hazardous area products.
