4 Misuse of the product may cause danger
or personal injury.
Product overview
PCM3051S chip adopts advanced MEMS
monocrystalline silicon pressure sensor chip. The
sensor signal is converted into a standard signal
output by a dedicated signal processing module.
After long-term aging and stability screening, the
product performance is stable and reliable. It is
applied to the outdoor scene where the environment
is harsh. At the same time, it can display on-site
pressure, zero point and full range migration.
The installation port form of PCM3051S
monocrystalline silicon pressure transmitter can be
processed according to the requirements of users,
and can also be compatible with other brands of
transmitters. This series of products are widely used
in industrial process control, petroleum, chemical,
metallurgical and other industries.
Notes:
1 Do not misuse documentation.

Installation diagram (for reference only)
Installation tips:
(1) The product is installed vertically on pressure port on site.
(2) When installing outdoor, the transmitter should be placed in a
ventilated and dry place as far as possible to avoid direct sunlight
and rain, otherwise the performance will be deteriorated or
malfunction.
(3) When the product is installed in frequent lightning areas, it
should be marked with “Lightning Protection” when ordering. It is
also recommended that users install lightning protection device
on site and ensure reliable grounding of product and power
supply, which can reduce the probability of lightning damage to
the transmitter.
(4) If the transmitter is found to have no output or the output is
abnormal after installation, please check:
a Whether the electrical connection is accurate and firm
b Is the supply voltage too low or the load resistance is too large
