The finger type pressure transmitter is made up of a ceramic/silicone sensor housed in a stainless steel housing or a piezoresistive measuring cell and an electronic card located on a stainless steel 316L housing. The sensor design ensures that reliability is maintained during temperature changes and overload.
The use of a stainless steel 316L diaphragm or a ceramic/silicone sensor ensures high linearity over the entire measurement range, while minimizing the hyster December effect.
Mode of operation
The stainless steel 316L diaphragm and ceramic sensor sense the physical deviations of elements under pressure. Mechanical deformation is transferred to an electrical signal by converting it from the diaphragm and the ceramic sensor by a resistance bridge. An amplifier converts the output voltage of the cell to 4-20mA / 0-10V, which is the output current signal of the transmitter.
The Pressure Transmitter is powered by an external stable power supply. The reverse pole and high supply voltage are prevented by the protection diodes at the input. The device is also not affected by electromagnetic noise thanks to the EMC protective components inside.
