High Pressure Transducer

The high pressure transducer, is a new type of industrial pressure transmitter developed by our company. Stainless steel corrosion-resistant construction for pressure measurement of general liquids and gases. We can use it for: tap water, petroleum transmission, chemical process, and various system pressure measurement, to achieve measurement, control, alarm, dispatch, energy saving and other purposes.

Product Details

High pressure transducer

High-pressure transducer,

for measuring the level, flow and pressure of liquids,

gases or vapors at high operating pressures,

and then converting to a 4-20 mA DC signal output.

The intelligent high-pressure pressure transmitter can communicate with the HART Communicator

to set, track or form a field monitoring system with the host computer.

The high pressure transducer applications:

oil mining platforms, water flow equipment,

high-pressure measuring equipment, hydraulic control systems,

test benches and industrial automation control and feedback.

2.2.2. Simulation, linear:

The range and zero points are adjustable.

2.3. Zero positive and negative migration of  the high accuracy pressure transducers

For zero-point negative migration,

the lower range limit must be greater than or equal to -URL;

when the zeropointis being migrated, the upper range limit must be less than or equal to +URL.

The calibration range is greater than or equal to a small range.

2.4.Out put of the high pressure transducer

Digital, intelligence:

4~20mA DC.

The user can choose linear or square root output,

the digital process variable is superimposed on 4~20mA DC signal,

which the host computer adopting HART protocol can use.

Simulation, linear:

4 to 20 mA DC, linear with process pressure.

We use the HQ-1151/3051/3851/3351DP series of high pressure transmitters to measure:

the level, density, and pressure of liquids, gases or vapors,

and then convert them into 4-20 mA DC signal outputs.

The HQ-1151/3051/3851/3351DP intelligent type can communicate with the HART Communicator,

to set, track or form an on-site monitoring system with the host computer.


field adjustable intelligent differential pressure transmitter is a new product,

developed by our company according to the requirements of the site.

We can separate it from the handheld communicator and realize on-site zero change,

and configuration operations by means of buttons.
