1. Product features:
JY pressure transmitter sensor adopts diffused silicon core as the sensing element, selects intelligent digital circuit, the overall performance is stable and reliable, and can carry out long-distance output. Easy to install, suitable for the measurement and control of gas, liquid, steam and other pressure.
（1）good stability, long-term stability of zero and full degree up to 0.2%FS/ year. Within the scope of compensation temperature – 30 ~ 70 ℃, the temperature drift less than 0.2% FS, throughout the allowed working temperature range is less than 0.5% FS.
（2）Can be used to measure the reaction with 316 stainless steel liquid, gas, steam.
（3）Solid structure, no moving parts, high reliability, long service life.
（4）From wind pressure to water and oil, high-precision measurement can be carried out regardless of the mass of the medium under test.
（5）Easy installation, simple structure, economical and durable.
2. Working principle:
pressure transmitter sensor Using piezoresistive pressure sensor principle, manufactured by silicon micro mechanical processing technology, pressure sensitive chip USES the imported, the chip is encapsulated within the 316 l stainless steel shell, and filling and filling silicone oil, medium pressure on stainless steel isolation diaphragm, by silicone oil to the sensitive chip, so as to output a linearly with the pressure is directly proportional to the voltage signal of change, after transformation of amplifying circuit, current, voltage output.
