Intelligent Digital Pressure Controller , High Accuracy Precision Pressure Gauge

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.

Parameter

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

• 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.
