High Accuracy Stainless Steel Power supply digital display Pressure
Controller
Description
The pressure transmitter is a crucial device designed to convert
physical pressure parameters, whether from gases or liquids, into
standardized electrical signals. This transformation allows for
control and remote transmission of the pressure-related data. The
device utilizes a diaphragm-filled hydraulic-electric pressure
sensor within its electronic structure. This innovative design
ensures the accuracy and reliability of the measurements.
Key features of the digital pressure transmitter include advanced
technology, excellent performance, reliable quality, and
user-friendly operation. The diaphragm-filled hydraulic-electric
pressure sensor is at the heart of its functionality. The
transmitter can accurately convert the sensed pressure into
standard electrical signals, such as 4~20mADC. These signals play a
crucial role in supplying secondary instruments like alarms,
recorders, and regulators with the necessary data for measurement,
indication, and process adjustment.
The digital nature of this pressure transmitter enhances its
versatility and adaptability across a range of industries. It finds
applications in petroleum, metallurgy, chemical, electric power,
building materials, hydrogeology, medical, and environmental
protection fields. Its usage extends to scientific research and
various production processes, contributing to efficient and precise
pressure monitoring and control.

Setting
AL1H: Switch connection point for switch 1(when pressure reaches this
value, indicator on) AL1F: Switch connection point for switch 1(when pressure reaches this
value, indicator off) AL2H: Switch connection point for switch 2(when pressure reaches this
value, indicator on) AL2F: Switch connection point for switch 2(when pressure reaches this
value, indicator off)
FILT: Filter coefficient. To avoid digit display from fluctuating which
is caused by pressure change, after 3-10seconds, it can be set END
then save then exit. The bigger the filter coefficient is, the more
stable it is, but the more hysteric.
Note:
Switching points are determined by the configuration of the present
connection and disconnection value.
When connection value is higher than disconnection value, it is
called upper-limit alarm output (normally open status);
When connection value is lower than disconnection value, it is
called lower-limit alarm output (normally close status);
The deviation between connection and disconnection value is the
return difference for the switch point.
Example (How to finish the settings as following)
- Set switch point 1 at upper-limit alarm output(normally open
status),connect at 4Mpa and disconnection when lower than
3.95Mpa,response delay is 3 seconds
- Set switch point 2 at lower-limit alarm output(normally close
status),connect at 10Mpa and disconnection when lower than
9.95Mpa,response delay is 10 seconds
Enter the menu: Set AL1H=4.00 AL1F=3.95 AL2H=9.95 AL2F=10.00
- Press “SET”
- “LOCK” sign(remind you to key in password,0001)
- Press ▲ or ▼ to key in the password
- Press “SET” to confirm
- Press ▲ or ▼as page up or page down to select (AL1H, AL1F, AL2H,
AL2F, END)
- Press “SET” to enter selection menu
- Press ▲or ▼ to alter the settings
- Press “SET” to confirm, or press ▲or▼to enter other menus for other
settings
Installation
1.Mechanical connection
It can be directly mounted in the hydraulic pipe by the connecting
thread. In critical application, such as server vibration or shock,
soft hose is recommended to use.
2.Electrical connection
To avoid electromagnetic interference, please know
a.the cable system should be as short as possible
b.To use shielded wire
c.To keep way from any interference resources, for example,
electric appliances and devices, if installed by soft hose, its
body should be grounded independently.
