Product Description High Temperature OEM Silicon Pressure Transmitter1.Product ApplicationThis product is widely used in fields such as petroleum, chemical engineering, sewage treatment, constant pressure water supply, environmental protection, machinery, metallurgy, power industry for measuring gauge pressure and absolute pressure. It can also measure negative pressure and is suitable for measuring and controlling the pressure of various liquids, gases, and steam in all-weather environments in various occasions.2.Product Features(1) It has good stability, with long-term stability at zero and full scale reaching 0.2%F.S/ year. Within the compensation temperature range of -30 to 70oC, the temperature drift is less than 0.2%F.S, and throughout the entire allowable operating temperature range, it is less than 0.5%F.S.(2) It can be used to measure liquids, gases and vapors that do not react with stainless steel. For highly corrosive media, a flange diaphragm structure can be selected.(3) Solid-state structure, no moving parts, high reliability and long service life.(4) It can accurately measure from wind pressure to water and oil, and is not affected by the mass of the medium being measured.(5) Easy to install, simple in structure, economical and durable.3.Working PrincipleThe pressure sensor adopts the piezoresistive principle and is manufactured through silicon micro-mechanical processing technology. The pressure-sensitive chip uses the original inlet and is encapsulated in a 316L stainless steel housing, filled with silicone oil. The medium pressure is applied to the stainless steel isolation diaphragm and transmitted to the sensitive chip through the silicone oil, thereby output a voltage signal that varies linearly proportional to the pressure. After conversion by the amplification circuit, current and voltage output are realized.4.Technical ParametersMeasurement rang-100 Kpa~ 0 ~ 100MPaMaximum overload1.5 times the rated pressurePressure formsgauge pressure, absolute pressure, negative pressureAccuracy grades0.5% 0.2% 0.1%Output signals4-20mA, 0-5V, 0-10V, RS485Power supply voltage12-36VDCLoad resistance≤500ΩMeasured medium liquid, gas, steamLong-term stability±0.2%F.S/ yearEnvironmental relative humidity0-90%Operating temperature-30~70oCPressure interface materialAll stainless steel in one piecePressure interfaceM20×1.5, G1/2, flush membrane, chuck connection, flange or user-definedDiaphragm material316L, tantalum, HC or as customized by the userNote: High-temperature accessories should be selected when the medium temperature exceeds 70oC.5.Factory workshop Tianjin Yiman Instrument Technology Co., Ltd. is a high-tech enterprise specializing in the research and development, manufacturing, sales and service of industrial automation instruments.
