DP56Aviation plug pressure transmitterIt is to diffuse a Wheatstone bridge on a single crystal silicon wafer, and apply pressure from the measured medium (gas or liquid) to change the resistance value of the bridge wall (piezoresistive effect), generating a differential voltage signal. This signal is amplified to convert the signal corresponding to the range into a standard analog signal or digital signal. Welcome to all customers.

1DP56Aviation plug pressure transmitterWorking principle

The diffusion silicon pressure core is used as the sensitive element, and the built-in processing circuit converts the sensor millivolt signal into standard voltage and current signals for output. It can be directly connected to computers, control instruments, display instruments, etc. By selecting high stability and reliability piezoresistive pressure sensors and high-performance transmitter circuits, the overall performance is stable and reliable, and long-distance signal transmission can be achieved. Adopting an integrated all stainless steel structure, it has undergone multiple stainless steel welding processes to achieve an all solid state design. It is easy to install and has extremely high vibration and impact resistance, making it suitable for long-term use in harsh environments.
