product description



Ceramic piezoresistive pressure sensor using alumina ceramic substrate for the measurement, no intermediate liquid dry pressure measurement technology, in the sense of pressure on the substrate with thick-film microelectronic technology will be pressure-sensitive resistance sintering ceramic base, the composition Wheatstone bridge , The linear correction, temperature correction can be accurate measurement of pressure.

Alumina ceramics superior corrosion resistance, can be in direct contact with the chemical medium and will not be corrosion, corrosion resistance than the proliferation of silicon sensors superior performance, longer service life.

Cost-effective than the proliferation of silicon sensors, cheap, applicable, the economy is its advantage.

Can be used with electronic circuit pressure, level transmitter, widely used in air pressure, hydraulic pressure, hydraulic measurement . Can be used for compressor pressure monitoring and control, automotive oil pressure, air conditioning, refrigeration, water pump automatic control , Hydraulic machinery automatic control , Chemical production and automatic control industries, the largest ceramic pressure sensor features corrosion-resistant! Long life!

Inexpensive and affordable for small water pump pressure control pressure detection.

installation

Correct installation of ceramic pressure sensor: Ceramic pressure sensor is the upper and lower two precision machined, high flatness, ceramic pressure sensor installation requirements and contact the two sides, that is, the bottom of the shell and metal pressure ring to the bottom surface is very smooth, Such as uneven, the consequences of the imbalance is the reaction of the pressure, there may be fracturing ceramic pressure sensor. Metal pressure ring diameter to be made 16 mm (pressure sensor circuit layout is 15 mm), so to avoid the pressure on the lead Leading to pressure is not smooth, short circuit and other undesirable phenomena.

Signal amplification and pressure calibration

1, ceramic pressure sensor output analog signal is small, requiring high resolution, generally do not directly A / D sampling, first with the instrument-level op amp amplification.

2, due to material error and the existence of sensor error, even after adjustment of the process, each sensor zero and full-scale output is only close to, not absolutely consistent, so the general instrumentation amplifier circuit to do the final output zero and full scale Only the pressure calibration becomes the standard signal output, the pressure of the signal to measure accurate, in order to be accepted by the microcontroller controller.

The ceramic pressure sensor is the same as the silicon pressure sensor:

The same: are used to measure the size of the pressure, the same principle, are the pressure on the diaphragm to produce pressure measurement
