Description



Product Overview


PCM400 Pressure Transmitter adopts the high performance and high stability OEM pressure sensor as the signal measuring element, and through the special signal processing, the sensor signal is transformed into the standard signal output; after the long-term aging and stability selecting, the product performance is stable and reliable, applies to the outdoor field with quite harsh environment, and meanwhile ensures the field pressure display, with zero and full span transferable.
For PCM400 Pressure Transmitter installation connection mode, it can be processed based on the user's requirement, or the specification compatible with the transmitters of other brands can be provided. The products of this series widely apply to the industrial process control, petroleum, chemical industry, metallurgy and other industries.
