China Jfa820 Flange Type Electronic Hot Water Diaphragm Mebrane Level Sensor

JFA820 Flange type electronic hot water diaphragm mebrane Level sensor

Overviews
JFA820 single flange level sensor, a high performance pressure transmitter with international
leading technology, which adopted a world advanced single crystal silicon pressure sensor
technology and patient packaging process. Single crystal silicon pressure sensor is located in top
of metallic ontology, far away from medium interface, isolated mechanical and thermal. Sensor
wiring which is glass sintering realize high strength electric insulation with metallic matrix, improved
flexible performance of the electrode circuit and protection ability for anti transient voltage.
The original signal crystal silicon pressure sensor packaging technology, ensure the transmitter
coping with complex chemical environment and mechanical load. Meanwhile, strong anti-
electromagnetic-interference capacity, which is enough for tough industry environment application.
This is invisible instrument truly.
