Compact pressure transmitter
Compact pressure transmitter
- It can be used to measure liquids, gases, and steam that do not react with stainless steel. Flange diaphragm structure can be selected for highly corrosive media;
- Solid structure, no moving parts, high reliability, long service life;
- From wind pressure to water and oil, high-precision measurements can be performed, and it is not affected by the mass of the measured medium;
- Easy to install, simple structure, economical and durable.
Product Overview：
Working Principle: The corrosion-resistant ceramic pressure sensor has no liquid transmission. The pressure acts directly on the front of the ceramic diaphragm, causing the diaphragm to deform slightly. The thick film resistor is printed on the back of the ceramic diaphragm and connected to form a Wheatstone bridge (closed bridge). Due to the piezoresistance effect of the varistor, the bridge generates a highly linear voltage signal that is proportional to the pressure and proportional to the excitation voltage. The standard signal is calibrated to 2.0/3.0/3.3mV/V according to the different pressure ranges, and can be compatible with strain sensors. Through laser calibration, the sensor has high temperature stability and time stability. The sensor has its own temperature compensation of 0~70℃ and can be in direct contact with most media.
The transmitter uses a ceramic piezoresistive sensor with a simple structure, small size and easy installation. It is widely used in aerospace, communications, water conservancy, petroleum, chemical industry, electric power, laboratory and other fields for gauge pressure and absolute pressure measurement, and can also measure negative pressure, vacuum, etc.
Aplicație:
Equipment monitoring: In power systems, pressure transmitters are widely used to monitor the pressure status of equipment such as boilers, steam turbines, and generators. With its small size and reliable performance, the compact pressure transmitter can be easily installed on various equipment to monitor its pressure changes in real time and ensure the safe operation of the equipment.
Sewage treatment: During the sewage treatment process, pressure transmitters are used to monitor the pressure changes of the treatment equipment. The compact pressure transmitter can be easily installed on various equipment and pipelines, providing accurate data support for sewage treatment, helping to optimize the treatment process and improve treatment efficiency.
Exhaust emissions: In exhaust emission monitoring, compact pressure transmitters also play an important role. They can monitor the pressure changes in the exhaust emission pipeline in real time, provide accurate monitoring data for environmental protection departments, and help control exhaust emissions and protect the environment.
