Signal conditioning circuitry processes the raw bridge output to deliver a linear 4-20 mA two-wire current loop response. Internal temperature compensation networks actively adjust for thermal drift across ambient operating thresholds, preventing offset errors during rapid temperature shifts. The wetted parts feature corrosion-resistant stainless steel construction to withstand exposure to hydraulic fluids, pneumatic media, and aggressive industrial chemicals without degradation of the pressure boundary.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the nominal supply voltage requirement for the 4-20 mA loop?\u003c\/p\u003e\n\u003cp\u003eA: The device operates on a standard loop power supply of 12 to 30 VDC, depending on total loop resistance and load calculations.\u003c\/p\u003e\n\u003cp\u003eQ: Is the transmitter protected against reverse polarity connection?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The internal terminal electronics incorporate diode protection circuitry to prevent physical hardware failure if supply polarity is inadvertently reversed during wiring.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum overpressure limit before sensor damage occurs?\u003c\/p\u003e\n\u003cp\u003eA: The burst pressure rating is established at 2 times the nominal full-scale range, while proof pressure limits permit up to 1.5 times full scale without calibration shift.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the process media temperature and static pressure do not exceed the specified operational limits of the sensor diaphragm prior to mechanical mounting.\u003c\/li\u003e\n\u003cli\u003eApply appropriate thread sealant or an O-ring seal compatible with the process media to the G 1\/4 process connection, tightening to recommended torque limits to prevent leakage.\u003c\/li\u003e\n\u003cli\u003eTerminate the 4-20 mA loop using shielded twisted-pair cable, grounding the shield exclusively at one end to minimize electromagnetic interference from nearby power circuits.\u003c\/li\u003e\n\u003cli\u003eVerify loop continuity and output scaling with a calibrated digital multimeter before energizing the control system input channel.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":48179988857022,"sku":"EZ1900-040","price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-10_16-05-55_ee369eb1-8f64-45e2-aa61-3f4efc90f8b9.png?v=1784627794","url":"https:\/\/www.autooiltech.com\/products\/emerson-epro-ez1900-040-pressure-transmitter","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
