High temperature pressure transmitter - Pressure Transmitters - Smart Pressure Transmitter

High temperature pressure transmitter I. Introduction high temperature pressure transmitter with high temperature, "sputtered film" Pressure chip assembly, the sensor can work long-term stability under high temperature conditions. Different lengths of fin assembly may further increase the temperature of the measured medium, scientific and rational configuration and advanced circuit design and temperature compensation, the transmitter can fully guarantee the long-term stability up to 300 ℃ environment to work in. With reverse polarity and current limit protection; laser trimming temperature compensation, zero and span can be adjusted in the field; wide range of corrosion-resistant, suitable for a variety of media; overload and anti-jamming ability, stable performance. Second, product application of the products are widely used in water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields, realize the measurement of liquid, gas, vapor pressures. High temperature pressure transmitter Third, the product parameters Measuring medium gaseous, liquid, oil and 316L Compatible media measurement form and scope gauge (G) --- the largest (0 ~ 60) MPa, the minimum (0 ~ 10) KPa absolute pressure (A) --- Maximum (0 ~ 60) MPa, the minimum (0 ~ 10) KPa negative pressure (B) --- (-0.1 ~ 60) MPa, minimum (-5 ~ 5) KPa Accuracy: 0.1, 0.25, 0.5 Overload: 2 to 5 times the range of long-term stability: less than 0.3% FS / Year Power supply: 15 ~ 36 VDC (calibration voltage 24VDC) output signal: (4 ~ 20) mA (two / three-wire system ), (0 ~ 10/20) mA (0 ~ 5) V, (1 ~ 5) V, (0 ~ 10) V Display: pointer meter or LCD display with optional calibration: By adjusting the precision potentiometers to achieve the zero and span adjustable working temperature of the liquid medium: (- 20 ~ 200) ℃ gaseous medium: (- 20 ~ 300) ℃ Compensation temperature: (- 20 ~ 300) ℃ Process connection: M20 × 1.5 external thread or a user specified Diaphragm material: 316L stainless steel Sensor Interface Materials: 1Cr18Ni9Ti Housing material: Aluminum alloy Protection class IP65 Fourth, the product selection table measuring high temperature pressure transmitter port form G, gauge A, absolute pressure B, sealing pressure (marked reference pressure value) S port output signal 1, (0 ~ 5) VDC 2, two-wire (4 ~ 20) mA (default) 3, (0 ~ 10) mA 4, other specified port P, 0.1% accuracy 2,0.2% 3,0.5% C 1 opening process connections, external thread M20 × 1.5 (default) 2, external thread G1 / 2 3, external thread NPT1 / 2 4, other note 5, M27 × 2 (flush Film standard interface) V port Display 1, no display (default), 0 to 100% linear indication 3, LCD digital range display (LCD) 4, LCD numbers 0 to 100 percent display (LCD) 5, LED digital tube 0 to 100% Display F mouth explosion class 1 standard, no explosion (default) 2, intrinsically safe (EXiaIICT4) 3, flameproof (EXdIIBT4) Order details: When selecting indicate pressure measurement range.
