Introduction: 3151GP pressure transmitter with the introduction of high-precision miniaturization of foreign advanced technology to produce smart sensors in the conversion principle of compensation for the use of digital technology on the temperature, static pressure to compensate, improve the measurement accuracy, reduce the temperature drift. Has a good long-term stability, high reliability, strong self-diagnostic ability. Its high performance and low cost, and to become the market's main transmitter Product Description Product Features leaving flexibility thanks to the microprocessor increases, enhanced with a strong self-diagnostic capability · zero and span adjustments are not mutually affecting both remote and local sound settings, calibration function wire system, in line with HART protocol HART protocol to communicate with the terminal without interrupting the output using digital compensation techniques to compensate for temperature and static pressure were good and stable performance, high precision, damping Adjustable, anti-overload strong unidirectional no mechanical transmission parts, less maintenance, strong vibration all the common parts, easy to maintain contact with the medium diaphragm material optional, all-weather use technical parameters Output signal: 4 ~ 20mA output superimposed ? HART protocol digital signal (two-wire) Power supply: External power supply 24V DC, (power range 12V ~ 45V) Installation: flameproof dⅡCT5, intrinsically safe iaⅡCT5 migration characteristics: positive and negative migration on its range, the lower limit shall over-range limit. At the minimum range, maximum positive transfer of 0.975URL; maximum negative migration for -URL temperature range: medium temperature -40 ~ 104 ℃, Storage temperature -40 ~ 85 ℃, the whole operating temperature -40 ~ 85 ℃ / -20 ~ 70 ℃ (with digital meter) Relative Humidity: 0 to 100% damping: The time constant is adjustable between 0.2 ~ 32.0s start time: 3s, no warm-up performance indicators: in the absence of migration, 316 stainless steel diaphragm and other under standard test conditions range ratio: 40: 1 accuracy: 3,4,5 turndown ratio of 1: 1 to 10: 1, the adjustment range is ± 0.1% of span ratio of 10: 1 to 40: 1:00 for ± 0.05 (1 + 0.1URL / Range)% range, the range is 6,7,8,9,0 turndown ratio of 1: 1 to 10: 1, for adjustment range ± 0.15% turndown ratio of 10 : 1:00, is ± 0.075 (1 + 0.1URL / Range)% range, stability:: 1-40 months is the maximum error of ± 0.15% of span overpressure effects: pressurized 140kgf / cm2, the maximum error scale range of ± 0.25% of the power effects: less than 0.005% of the output range / V Vibration effects: on any axis, the frequency of 200Hz, the error caused by the maximum scale range of ± 0.05% / g loading effects: Just enter the transmitter the voltage higher than 12V, no load impact load workspace. Installation Effect: Maximum produce no more than 0.25 kPa zero errors, but can be corrected, no effect on the range, measuring body without affecting the relative rotation of the flange
