Hydraulic chemical industry pressure sensor cost
Introduction
The use of advanced glass micro-melting technology to avoid the temperature, humidity, mechanical fatigue and medium product produced, thus to improve its long-term stability in the industrial environment. Pressure chamber is made of 17-4PH stainless steel whole process, no welding, no "O" ring, no leakage risks. The temperature sensor uses advanced digital compensation, has anti-interference ability, wide operating temperature range, long-term stability. This series has a variety of pressure and electrical connections for users to choose.
Silicon piezoresistive sensors with the international advanced level, with high-precision electronic components, through a rigorous process assembled. Give full play to the technical superiority of the sensor, so SNMB400 series universal pressure transmitter with excellent technical performance. It is too strong anti-overload and impact resistance, temperature drift, high stability, high measurement accuracy. SNMB400 Series Universal pressure transmitter optional pressure sensor is a solid state pressure-sensitive chip built with stainless steel diaphragm fully welded stainless steel body. Steel body internal perfusion silicone oil. The measured pressure acting on the diaphragm and transmitted to the sensitive chip by silicone oil. Sensitive chip through wires with a dedicated amplification circuit is connected to the transmitter. It utilizes the piezoresistive effect of semiconductor silicon materials, to achieve pressure and electrical conversion. Since the electrical signal and the role of the Wheatstone bridge output pressure sensitive chip has a good linear relationship, it is possible to achieve an accurate measurement of the pressure.
Product Features
1.Anti-overload and impact resistance, high stability: better than 0.2% full scale per year;
2.Anti-interference ability is strong, waterproof, dustproof, shockproof, explosion-proof, anti-corrosion;
3.Wide applicability: the product has a variety of models, a variety of process connection forms, a variety of process connection material, can be suitable for measurement in various situations;
4.Easy installation: products reasonable structure, small volume, light weight, can be directly installed at any position.
5.Transmitter consists of a sensor and signal processing circuit, wherein the sensor surface with a pressure-sensitive Wheatstone bridge, when increasing the pressure, the bridge each arm resistance value changes. By a signal processing circuit, it is converted into a voltage change, which will eventually be converted into a standard (4 ~ 20) mA DC signal output.
6.Advanced digital temperature compensation and wide working temperature scope
7.High sensibility, high precision, high frequency response and permanent stability
8.Excellent resistance against impact, overload, shock and erosion
