Flange Pressure Transmitter

Works measured pressure acts directly in front of the pressure sensor diaphragm, the diaphragm will produce slight deformation, the sensor produces a highly linear proportional to the pressure, voltage excitation voltage signal proportional to the voltage signal, sensor output After the differential amplifier output normalized after an amplification, then the current through voltage conversion, into a corresponding current signal, the current signal by compensating for the nonlinear correction loop, i.e., with the input pressure produces a linear correspondence relationship 1 ~ 5V or 4 ~ 20mA standard signal output. I. Overview of the series pressure transmitter made of imported high-quality imported pressure sensor, using a dedicated integrated module, the fine temperature, zero, span, and non-linear compensation, to achieve the liquid, gas, steam and other media pressure change accurately measurement and transmission. A full range of pressure transmitter with HART communication can be, 485, CAN bus communication, and optional LED, LCD header. The transmitter can be in the field or control room for remote control or system configuration via PC or handheld device (communication device). This series has a variety of interfaces in the form, full of different specifications to satisfy customer needs, especially for widely used in various industrial scene. The series meets GB3836.4-2000 "electrical equipment for explosive gas atmospheres Part 4 Intrinsic Safety" i "" and GB3638.1-2000 "electrical equipment for explosive gas atmospheres Part 1 General requirements", proof mark: ExiaⅡC T6, it applies to 0, Zone 1 and Zone 2 contains ⅡA ~ ⅡC class venues T1 ~ T6 group explosive gas mixtures and explosion-proof electrical products by the State Quality Inspection Center of qualified, made explosion-proof certificate number: CNEx08. 1964.
