WP402 pressure transmitter output stability is generally high sensitivity strain sensor output is only about 10mv, diffused silicon sensor full-scale output of about 100mv, interference and noise and other factors is relatively small, the resolution is greatly improved, no dead near zero pressure area. High accuracy and good reproducibility WP402 diffused silicon piezoresistive pressure sensor to achieve a sense of pressure by the pressure transmitting electrical conversion is implemented by the same element, without intermediate transformation stage, no pressure hysteresis, no mechanical displacement deformation, ensuring minimal repeatability and hysteresis error, good linearity, stability, reliability and long life. WP402 pressure transmitter selection: wherein G represents a gauge pressure, follow the code represents the measurement range, detailed pressure transmitter selection code are welcome to inquire. WP402 pressure transmitter wiring: two-wire a negative three vacant four n-grounded. WP402 three-wire pressure transmitter wiring 1 Power positive, 2 negative output minus 3 power output positive 4 Ground. Smart Pressure Transmitter WP402 adopted by computer automated testing and using laser trimming technology for the wide temperature range of zero and sensitivity compensation with stainless steel isolation diaphragm piezoresistive OEM sensor as a signal measuring element, the sensor signal via the signal processing circuit after converted to a standard signal output, the product after a long-term aging and stability assessment and other processes strict screening, stable and reliable performance. The product is two-wire 4 ~ 20mADC site digital display pressure transmitter oil pressure sensor WP402 applied to the work environment is harsh, while required to live shows measured pressure of the occasion, for petroleum, chemical, metallurgy, electricity, etc. pressure industrial process measurement. WP402 pressure transmitter oil pressure sensor test procedures in line with national industry standards, intelligent pressure transmitter WP402 price, factory outlets. Smart Pressure Transmitter WP402 installation, first check the requirements and drawings on signs parameters are the same, then with a wrench hex mounting screws, and then press wiring wiring.
