Detailed Product Description

SYB-A general using type

Series SYB pressure transmitter adopts ceramic transducer of advanced international level, matches high accuracy electric units, and assemble through strict process. It applies dry-type pressure measuring technique which hasnt medium, which give full scope of ceramic technique advantages. That makes SYB series pressure transmitter has many models, many measuring range, many process connecting type and connecting material, and can be widely used in various lines of petroleum, chemical, electrical, metallurgy, medicine, food and so on. It can measure various environment and medium and is the replacement of traditional product. Also it is your ideal night measuring meters as industry automatic gauge.

1) main features:

l       Ceramic measure surface, high anticorrosion

l       No extra fluid, no industry pollution.

l       High ability of overload resist and impact force resist. Pressure can over up to several to hundreds times of the normal range.(ceramic capacity transducer)

l        High static features and have got the advantage over 0.1% FS.

l       Due to non extra fluid, transducer has very high accuracy and little affected by temperature.

l       High ability interfere resistance

l       Easy to installation, reasonable structure, small volume, light in weight, can install in any position and wont influence by the position.

2) working principle:

The pressure acts directly on ceramic membrane, and the membrane moves little displacement direct proportional to the fluid pressure. And normally, the biggest displacement of membrane is less than 0.025mm. when electric circuit detects this displacement and then change the relevant pressure into standard industrial measuring signal. When it is overpressure, the membrane sticks to solid ceramic basal corpuscle directly. There are only 0.1mm distance between membrane and basal corpuscle, so the maximum displacement of membrane can only be 0.1mm. Therefore the membrane in structure wont be damaged. And furthermore the membrane adopt ceramic material, it has high ability of resisting impact force and overload.

4)electric connection:

To convenience you, SYB serious pressure transmitter can connect wires neednt recognize positive and negative poles.

Picture two:

Two line system, terminator 1 connects terminator 3, neednt differentiate positive and negative poles

Two line system, when matched with local indicating meter, terminator 1 connects with battery positive pole, terminal 3 connects with battery negative pole. Terminal 4 and terminal 5 connect with meter.
