Pressure range from –1.5psi to –4psi (from –1 to –2758kPa)
Reference accuracy, including linearity, hysteresis and repeatability
Turndown ratio 1:1
Lighter weight and compact size facilitate installation and handling 5 years of stability under actual process conditions.
The pressure range of 351GP can reach 4psi. The 351GP is equipped with a fully configurable liquid crystal display (LCD), which can display pressure and diagnostic information. Small, light, easy to install and transport.
Even in harsh applications, the 351GP can provide accurate, stable and reliable pressure measurement results. This design requires a low amount of filling oil, so that the transmitter is less affected by temperature and accuracy.
TheRosemount 351GP pressure transmitter is one of the series of pressure transmitters from the American Rosemount company that has passed the test of the power industry for 4 years. It is designed with high performance, long-term stability and easy maintenance. Whether from design to installation, from maintenance to operation, the measurement concept is realized.
Rosemount 351 pressure transmitter is a pressure measurement product in the industrial field. At present, there are four factories in the world supplying original 351 transmitters. The ones that supply China are Beijing Far East Rosemount Co., Ltd. and Singapore Rosemount Pte Ltd. Among them, the 1151 original products are only provided by Beijing Far East Rosemount Co., Ltd.
Pressure range
Reference accuracy from –1.5psi–psi (from –1 to –2758kPa), including linearity, hysteresis and repeatability. Range ratio 1:1. Lighter weight and compact size facilitate installation and handling
It can be stable for 5 years under actual process conditions.
Reference accuracy
± Calibration range. Including the combined effects of linearity, hysteresis and repeatability. For ranges with a turndown ratio of less than 5:1, accuracy = ±[25+(1) (URL/range)] range
Ambient temperature influence
The overall impact is expressed as follows
±(URL+.range)/5°F(28°C)
Ambient temperature range from –4°F to 185°F (-4°C to 85°C)
Stability
For a temperature change of ±5°F (28°C), ±.1URL within 5 years.
Vibration influence
Only the resonant frequency is considered, and other vibration effects are ignored. Under resonance, 15-2Hz vibration is applied at any angle to the axis of the pipe for testing, and the vibration impact is less than ±URL/g.
Power influence
Less than ± standard range/V
Influence of installation location
The point drift can reach 2.5inH2O (63.5mmH2), but it can be corrected. No range effect.
Radio Frequency Interference (RFI) Impact
Less than ± upper range limit (URL) (2–1MHz, 3V/m, lead with piping). Less than ± upper range limit (URL) (2–1MHz, 1V/m, using unshielded twisted pair, no piping).
