Description
Technical field
The utility model belongs to electrical category, and particularly automobile, tractor engine oil pressure alarm sensor refer to be applied to the engine motor oil pressure warning sensor of automobile, tractor especially.
The utility model automobile, tractor engine oil pressure pickup are mainly used in automobile and tractor engine, cooperate with corresponding oil manometer and engine oil pressure alarm, can finish engine lubrication system main oil gallery pressure detection and oil pressure simultaneously and cross the low two kinds of functions of indication of reporting to the police.
Background technology
Present domestic existing engine oil pressure alarm sensor, general slip formula oil pressure sensor and the bimetallic strip structure electrothermal engine oil pressure alarm sensor of adopting, exist precision low, quality of production poor stability, life-span is short, it is poor to seal, output signal can not with shortcomings such as digital instrumentation is complementary, again because automobile, tractor needs to run at high speed on the road surface of various complexity in the open air, the actual condition of work of bearing of engine oil pressure pickup is very abominable, need have good anti-height, cryogenic property, also to have and bear frequent impact, vibrations, performances such as corrosion and overload, so mechanical structure type sensor, along with automobile, the development of tractor industry, can not satisfy new automobile, the needs of tractor need further to be improved.
The utility model content
The purpose of this utility model is: adopt special-purpose automobile, tractor engine oil pressure alarm sensor, solve existing slip formula oil pressure sensor and bimetallic strip structure electrothermal engine oil pressure alarm sensor, have that precision is low, quality of production poor stability, the life-span is short, sealing is poor, output signal can not with shortcomings such as digital instrumentation is complementary.
Automobile, tractor engine oil pressure pickup by wiring board, lead-in wire, the O-ring seal of the wiring board of sexangle base, shell, pressure sensor chip, vertical Signal Regulation and power supply protective circuit of voltage regulation, draw pin, binding post, wire harness and constitute.
The utility model engine oil pressure alarm sensor comprises pressure sensor chip, amplifying circuit, single-chip microcomputer, power circuit and warning light control circuit.The Single-chip Controlling pressure sensor chip reads the oil pressure value of engine, and pressure sensor chip outputs to single-chip microcomputer with the oil pressure value that reads; Oil pressure gauge indication control circuit is received in the output of single-chip microcomputer, and external oil pressure gauge is received in the output of oil pressure gauge indication control circuit, and the Single-chip Controlling oil pressure gauge provides the oil pressure indication and warning light shows.
Pressure sensor chip adopts special-purpose presser sensor sensor chip, improved the precision of gaging pressure greatly, the signal end of single-chip microcomputer, warning end are received the precision that oil pressure gauge is indicated the signal input of control circuit respectively, and the signal input part of receiving oil pressure gauge indication control circuit respectively, the warning input end that reaches the warning light control circuit are held in the signal end of single-chip microcomputer, warning; The control oil pressure gauge provides the oil pressure indication, the temperature of the instant working temperature of gaging pressure, instrument demonstration control and alarm and the high and low temperature of operation, and pressure alarm point can pass through software set as requested, and has the pressure measurement range of broad.
The structure of automobile, tractor engine oil pressure alarm sensor comprises: the wiring board of three go between or draw pin and vertical Signal Regulation and the wiring board power supply protective circuit of voltage regulation and special-purpose pressure sensor chips is connected; The wiring board of special-purpose pressure sensor chip is connected with sensor base; The top installation wiring of binding post also is connected with automobile, tractor oil manometer; O-ring seal is installed in the groove of sensor base, and special-purpose pressure sensor chip is welded on the wiring board above the O-ring seal.Above-mentioned main part adopts heat insulation chemical coating to smear.
The utility model automobile, tractor engine oil pressure pickup can substitute existing machinery formula pressure transducer, directly be connected with the low pressure alarming lamp with automobile, tractor engine oil pressure indicating gauge, indicate the engine oil pressure of automobile, tractor engine and the low pressure alarming signal be provided, have following advantage:
1 assembling is simple, and good endurance stands the repeat pressure test 20,000 times;
2 no mechanical contacts, output characteristics are satisfied institute and are joined the oil pressure gauge characteristic, meet " automobile, used with tractor tensimeter " standard;
3 have the low pressure alarming function is used for abominable automobile, tractor running environment, can use in high low temperature, vibration, thermal shock and rugged surroundings such as physical shock and chemical contamination, is mainly used in engine oil pressure and measures;
4 holding circuits design and highly integrated has improved stability, the reliability height;
5 precision height, signal amplifies, and is convenient to operation.
