High Temperature Diaphragm Pressure Transmitter

I. Product Overview:

ZW3051GP series high temperature diaphragm pressure transducer is a transducer for measuring pressure in high and low temperature environment. It uses foreign professional sensors. The transducer acts directly on stainless steel diaphragm in pressure medium and produces resistance film of "micron" level by molecular bonding. The Whiston bridge is fabricated by microelectronics technology. It consists of all-metal sensitive elements, no adhesive and movable parts, no sealing cavity and oil filling cavity. It is suitable for harsh environment and long-term stable work. The high temperature pressure transmitter has the remarkable characteristics of small temperature drift, wide temperature range, wide temperature range of measuring medium (high temperature up to 150 C), arbitrary installation, good long-term stability, wear resistance, impact resistance and corrosion resistance. After rigorous testing and aging screening, the product has reliable performance and can work stably in high and low temperature environment for a long time. It can be widely used in pressure measurement in many fields.

II. Working Principle:

The principle of ZW3051GP series high temperature diaphragm pressure transmitter is that a capacitor is composed of the measuring diaphragm and the electrodes on both sides of the insulating diaphragm. When the pressure on both sides is inconsistent, the displacement of the diaphragm is proportional to the pressure difference, so the capacitance on both sides is different. Through oscillation and demodulation, the diaphragm is converted into a signal proportional to the pressure, and then transformed into a standard electrical signal through temperature compensation and linear correction.

3. Application occasions:

The main structure of ZW3051GP series high temperature diaphragm pressure transmitter is the same as that of pressure transmitter. In order to meet the different installation requirements, this series of transmitter has a variety of remote transmission devices for users to choose. This product is widely used in petroleum, chemical, power, food, paper, municipal engineering and other industries.

1. Viscous media at high temperature;

2. Easy to crystallize medium;

3. Precipitable media with solid particles or suspended solids;

4. Strong corrosive or highly toxic media;

It can eliminate the leakage of the guide pipe and pollute the surrounding environment, and avoid the tedious work of supplementing the isolation fluid frequently because of the instability of the measurement signal when using the isolation fluid.

5. Continuous and accurate measurement of interface and density;

The remote transmission device can avoid the mixing of different instantaneous media, so that the measured results can truly reflect the actual situation of process changes.

6. occasions with high requirements for hygiene and cleanliness;

For example, in the production of food, beverage and medicine industry, it is not only required that the contact media parts of transmitters meet the hygienic standards, but also should be easy to rinse to prevent cross-contamination of different batches of media.
