We develop and produce OEM pressure sensors using piezoresistive technology for high standards in our own plant. The piezoresistive diffused silicon pressure sensor uses a high-precision semiconductor resistance strain gauge to form a Wheatstone bridge as a force-electric conversion measurement circuit. It has high measurement accuracy, low power consumption, and extremely low cost, with our…

Pressure measurement plays a central role in many applications – from machine tooling to process engineering to manufacturing and processing food and beverages. Sometimes the process temperature in these applications exceeds the limits of pressure instrumentation, which can make it difficult to accurately monitor, measure, and control pressure. The trick is to ensure that the…

The anti-corrosion ceramic pressure sensor has no liquid transmission. The pressure directly acts on the front surface of the ceramic diaphragm, causing the membrane to deform slightly. The thick film resistor is printed on the back of the ceramic diaphragm and connected to a Wheatstone bridge (closed), due to the piezoresistive effect of the varistor,…

Use the pressure sensor solution to complete the gas pressure measurement. The pressure sensor is a conversion device used for gas pressure measurement is mainly used to measure the absolute pressure of the gas, can be used for blood pressure, wind pressure, pipeline gas and other aspects of pressure measurement. The performance is stable and…

We get asked this from time to time when someone has seen the quotation of cheap pressure transmitters from other suppliers. There are a lot of differences between a cheap $10 transmitter and a robust $100 unit. It all boils down to accuracy and reliability and the necessary manufacturing processes to go along with them….

Piezoresistive pressure sensors can be classified in terms of pressure ranges they measure, temperature ranges of operation, and most importantly the type of pressure they measure. In terms of pressure type, pressure sensors can be divided into five categories: Absolute piezoresistive pressure transducer This transducer measures the pressure relative to perfect vacuum pressure (0 PSI…

To select the right pressure sensor for a specific application besides the pressure range first of all the type of pressure measurement has to be considered. Pressure sensors measure a certain pressure in comparison to a reference pressure and can be divided into absolute, gauge and differential devices. These terms will be explained on the…
