Generator/engine clamp oil pressure sensor

A.Summary

Gripping oil hydraulic sensor is designed for measuring diesel high-pressure tube pressure waveforms of internal combustion engine research and development of new type of piezoelectric sensors, detecting without remove any component engine, need to put sensors card high-pressure tube. Simple structure, convenient installation sensor is very suitable for diesel engine oil injection pressure, rotational speed, oil injection timing of extraction of non-dismatiement testing. Used in diesel engines and railway car manufacturing, research and development of internal combustion engine performance test, maintenance, etc.

B.Function and characteristics

L non-dismatiement testing: just sensing card loaded to high pressure on the tubing can test, realize the not the disintegration of the pipe pressure measuring technology breakthrough.

L high sensitivity, signal stability: the product structure by clamping ring, sensitive body, base, clamping device, signal output device five parts, the main parts are made of two pieces of induction characteristics of piezoelectric symmetrical, rise to suppress the interference signals, the effect, therefore the can from engine strong vibration injection removed when the wall strain signal.

L strong corrosion resistance, by the high strength copper alloy as stress frame, the tubing interface plating, whole shell plating chromium processing, product service life long.

L detection principle advanced: when the engine oil spraying, tubing in high pressure oil under the action of small pulse produce inflation, thus squeezing sensor sensitive body produce charge output, the output charge the special difference charge amplifier amplification conversion for second instrument collection and analysis. The output of the sensor only with the injection pressure into linear relationship between the only.
