Honghua 珩 micro pressure sensor / transmitter features:

1: The diffused silicon pressure-sensitive core body with imported isolation diaphragm structure is used to measure the viscous strong medium. When the pressure is too small, it has high-precision signal output and resolution.

2: The use of full 316L stainless steel connection makes the sensor shell more sturdy, and the long rust-proof effect is better compared with other materials.

3: The amplification system independently developed by Honghuayu reduces the coefficient of zero deadband of the sensor "dead zone".

4: The adjustment system is tested by the National Metrology Institute, which makes the sensor accuracy truly improved.

5: The stainless steel connection process is used to seamlessly connect the sensor, so that the sensor has a long working life under the harsh working environment. The imported pressure sensitive chip, all stainless steel sealing structure has good moisture resistance and excellent


Different media compatibility.

6: The probe adopts the test head without pressure hole structure, which solves the situation that there is clogging of viscous medium during the measurement process.

      Applicable to: diaphragm type micro pressure pressure sensor elastomer adopts imported material, diaphragm isolation process, test head without pressure hole, no viscous medium blockage during measurement, integrated structure design, micro pressure


Pressure sensing chip for pressure measurement and control of weak pressure chemical coatings, paints, slurries, asphalt, crude oil and other viscous media.

These types of sensors are also commonly referred to as: flat membrane pressure sensors, diaphragm pressure transmitters, chemical pressure sensors, chemical pressure transmitters, paint pressure sensors, paint pressure transmitters, food pressure sensors, food pressures.
