PCM91 Single Crystal Silicon Single Pressure Module

Product overview

The internal die of PCM91 monocrystalline silicon pressure module adopts a German imported MEMS monocrystalline silicon pressure die. The sensor signal is converted into a standard signal output through a dedicated signal processing module. After long-term aging and stability screening, the product performance is stable and reliable. At the same time, it can display on-site pressure, zero point, and full range migration.

The PCM91 single crystal silicon single pressure component installation interface form can be processed according to user requirements, and can also provide specifications compatible with other brands of transmitters. This series of products is widely used in industrial process control, petroleum, chemical, metallurgical and other industries.
