China's domestic instrument manufacturers OEM for foreign manufacturers Pressure transmitters Some foreign manufacturers, in addition to importing a small amount of new instrument products to meet the high-end demands of the Chinese market, have been entrusted by Chinese domestic manufacturers to OEM for the consideration of operating channels and production costs. produce. Foreign manufacturers provide sensors, and other parts are commissioned by local Chinese manufacturers for processing.

Chinese instrument manufacturers use pressure sensors of foreign manufacturers in high-end pressure transmitters. Since the high-end pressure sensor technology of pressure transmitters is still in the hands of foreign manufacturers, Chinese domestic instrument manufacturers are facing pressure transmitters for high-end markets. The pressure sensors used are from foreign manufacturers.

China's small and medium-sized pressure transmitter manufacturers use pressure sensors provided by mainstream Chinese manufacturers. This situation is common in the pressure transmitter market. Pressure sensor technology is the core technology of pressure transmitters and is only known to a small number of manufacturers. High-end technology is monopolized by foreign manufacturers. At present, a few Chinese mainstream pressure transmitter manufacturers can produce sensor products based on the 1151 technology. Therefore, most small and medium-sized pressure transmitter manufacturers need to purchase pressure sensor products through these core technology vendors (mainly Chinese manufacturers) to assemble pressure transmitters.
