Diffuse silicon pressure transmitters have advantages such as reliable operation, stable performance, easy installation and use, small size, light weight, and high cost-effectiveness, and can be widely used in various positive and negative pressure measurements. The diffusion silicon pressure transmitter uses imported diffusion silicon or ceramic core as the pressure detection element, and the sensor signal is converted into a unified output signal of 0-10mA or 4-20mA through a high-performance electronic amplifier. Pressure transmitters can replace traditional remote pressure gauges, Hall elements, differential transmitters, and have the performance of DDZ-II and DDZ-III transmitters. The diffusion silicon pressure transmitter can be used in conjunction with various types of dynamic coil indicators, digital pressure gauges, electronic potentiometers, as well as with various automatic adjustment systems or computer systems.
