Product Details

3351 Metal Capacitive Diaphragm

The type 3351 film is a type 1151 metal capacitive pressure sensor core, which is unique in the package and integrated in a sealed chamber, which provides a real time temperature parameter for the digital compensation circuit of the sensor. Therefore, the film can be accurately compensated for temperature. In this way, the transmitter used 3351 capsule, the accuracy level of which can usually reach 0.1.

Type 3351 membrane has all the advantages of type 1151 sensor. If the combination of the digital circuit with the internal package, it can provide the 4-20mA output signal, HART protocol optional. Widely used in chemical, water and electricity, metallurgy and other industrial areas of the capacitive transmitter, which is the core part of the 3351 Series Capsule.

Main features:

Use of advanced customized anaerobic sintering furnace, sensor filled pipe and glass sintering with atmospheric isolation, filled pipe does not produce oxide layer, to avoid the short circuit phenomenon caused by oxide sensor center diaphragm and between the capacitor plates.

Adopt computer control positioning and tensioning technology, make the center diaphragm accurate positioning, moderate tension, accuracy is greatly improved.

Adopt imported high quality material and the center diaphragm filled with silicone oil.

] every film box strictly according to the process after more than 1000 times of fatigue aging test, and ensure the stability of the product by 5 ~ 60MPa bi-directional single overload test and static test.
