TRH-P-204 Vacuum / Micro Pressure / Negative Pressure Sensor / Transmitter
TRH-P-204 micro pressure sensor, micro pressure transmitter
Honghua 珩 electronic micro pressure sensor / transmitter features:
1: It adopts imported diffused silicon pressure sensitive core body with high precision signal output and resolution.
2: The 316L stainless steel connection makes the sensor housing more sturdy, and the long rust-proof effect is better compared with other materials.
3: The amplification system using electronic independent research and development 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.
The 5:204S adopts a high-precision display head integrated structure.
The 6:204H case adds a desuperheater, and the use of a high temperature resistant pressure core makes the sensor instantaneously reach a temperature of 200 degrees during use, and does not affect the sensor's high precision measurement.
It is suitable for the measurement and control of micro pressure and pressure where the medium pressure is weak.
