**Designed to Meet the Stringent Requirements for use in Hazardous Industrial Locations Such as:** **PX835 Series shown actual size.** - **Oil Field Equipment** - **Upstream Oil and Gas Production** - **Natural Gas Compression and Transfer Control** - **Alternative Energy Projects** - **Fuel Cell Manufacturing** The PX835 explosion proof pressure transmitter is ideal for a broad spectrum of pressure sensing requirements, requiring approvals for explosion/flame proof. The PX835 is designed with an all welded stainless steel case and manufactured to provide the user with accurate, reliable, and stable output data. This is accomplished through the use of state of the art sensor technology combined with digital calibration to provide extremely linear and precise performance over the entire specified pressure and temperature range. ## **SPECIFICATIONS** **Output:** 4 to 20 mAdc (2-wire) **Supply Voltage:** 12 to 32 Vdc Vmin = 12 V + (0.022A x loop res) **Insulation Resistance (Circuit to Case):** 100M Ω @ 30 Vdc **Circuit Protection:** Reverse polarity and mis-wire protected **==> picture [47 x 6] intentionally omitted <==** **----- Start of picture text -----**
