31 US Series and 32US Heavy Duty Series UL Listed Intrinsically Safe Industrial Pressure Sensors For OEMs that need Intrinsically Safe pressure sensors with consistent high levels of performance, reliability and stability, the 31/32US Series sputtered thin film units offer an unbeatable price performance ratio in a small package size. They feature all stainless steel wetted parts, a broad selection of electrical and pressure connections and a wide choice of electrical outputs. Our manufacturing process includes the latest automated equipment, producing consistent sensor performance. Additionally the 32US Series sensors feature a thicker diaphragm and a pressure restrictor to withstand the rigors of cavitation or extreme pressure spikes, delivering years of reliable and stable performance in pulsating applications. The compact construction of both these series makes them ideal for installation where space is at a premium.
