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.

Installation instruction (for reference only)
Installation suggestion:
(1) The product is installed vertically on the field pressure connection.
(2) During the outdoor installation, try to put the transmitter in a dry and ventilated place,
and avoid direct strong sunshine and rain, or else the performance will become poor or
break down.
(3) When the product is installed in the area with frequent lightning, “lightning protection”
should be indicated when ordering; meanwhile, we suggest that the user additionally install
the lightning protection equipment on site, and ensure reliable grounding of the product and
the power supply, which can reduce the probability of the transmitter damage caused by the
lightning.
(4) If no output or abnormal output of the transmitter is found after the installation, please
check:
①Whether the electrical connection is accurate and firm;
②Whether the supply voltage is too low and whether the load resistance is too high.
