Description
Technical field: the utility model relates to the sensor of automobile industry, particularly a kind of sensor that is used for measuring engine motor oil pressure on the diesel automobile engine that is installed in.
Background technique: the engine oil pressure of motor car engine is one of important parameter of diesel engine.All be a mechanical compression sensor to be installed come the measuring machine oil pressure on motor at present on the automobile, this mechanical compression sensor is made up of a convolution diaphragm and a slide-wire potentiometer.When automobile engine oil pressure changed, convolution diaphragm produced displacement, and sliding in the contact that drives on the potentiometer, thereby changes its resistance value.
This potentiometer is connected with oil pressure index gauge on being installed in automobile instrument panel by a lead.When the resistance of potentiometer changed, the electric current that oil pressure index gauge Inside coil passes through changed, thereby drove throw of pointer, indicated the engine oil pressure value.The slide-wire potentiometer that adopts in this oil pressure measuring device has mechanical contact, and this contact will be by the electric current of 100 milliamperes of up, and automobile exists and bigger jolt and vibrate, make that machinery, the electrical endurance of this sensor are had a strong impact on, become the principal element that the automobile engine oil pressure transducer lost efficacy.
Summary of the invention: technical problem to be solved in the utility model provides a kind of automobile engine oil pressure transducer, it can substitute the mechanical compression sensor, directly be connected with the low pressure alarming lamp, indicate the engine oil pressure of diesel automobile engine and the low pressure alarming signal is provided with the automobile engine oil pressure indicator.Technical problem of the present utility model is achieved by following technical proposals:
A kind of automobile engine oil pressure transducer comprises thick film pressure transducer chip (4), signal conditioner circuit board (6), it is characterized in that: seal ring (3) is installed in the groove of sensor body (1), thick film pressure transducer chip (4) be installed in seal ring (3) above, fastening piece (5) in the middle of screwing, thick film pressure transducer chip (4) and sensor body (1) closely are fixed together, and thick film pressure transducer chip (4) is formed Seal cage with sensor body (1), seal ring (3) and is experienced engine oil pressure;
Three screw rods (10) are fixed on signal conditioner circuit board (6) on the sensor body (1) by double-screw bolt (7) and compression spring (8), hold-down ring (9), housing (2) are fixed together by mechanical rolling with sensor body (1), and connecting line (12) is installed on the top of wiring terminal (11):
The ground wire of automobile engine oil pressure transducer body (1) links to each other with the ground wire of engine oil pressure index gauge I, and signaling line G is connected with engine oil pressure index gauge I, and alarming line W is connected with low pressure alarming lamp L, and Placement and mechanical type oil pressure sensor are identical.A kind of beneficial effect of automobile engine oil pressure transducer: 1. assembling is simple; 2. there is not mechanical contact; 3. has the low pressure alarming function; 4. the mode of connection and traditional mechanical sensor are in full accord, can directly substitute; 5. reliability height.
Description of drawings: Fig. 1 is the structural representation of automobile engine oil pressure transducer.Fig. 2 is the circuit connecting line figure between automobile engine oil pressure transducer and automobile engine oil pressure indicator, the low pressure alarming lamp.
Embodiment: embodiment of the present utility model is further described below in conjunction with accompanying drawing:
Automobile engine oil pressure transducer body 1 is installed on the diesel automobile engine, when engine start, the machine oil of motor enters by the aperture on the sensor body 1 in the Seal cage of being made up of body 1, seal ring 3, thick film pressure transducer chip 4, and the engine oil pressure in the Seal cage is consistent with in-engine engine oil pressure.When the rotating speed of motor changed, the engine oil pressure of motor was also different, and rotating speed is fast more, and engine oil pressure is big more; Rotating speed is slow more, and engine oil pressure is more little.
Thick film pressure transducer chip 4 is directly experienced the pressure of Seal cage, and converts pressure signal to voltage signal, and the size of voltage signal is directly proportional with engine oil pressure, and engine oil pressure is big more, and the voltage signal of thick film pressure transducer chip 4 outputs is big more.Signal conditioner circuit board 6 with the voltage signal of thick film pressure transducer chip 4 output carry out voltage amplification, electric current amplifies and alarm pressure relatively after, output engine oil pressure signal and alarm pressure signal.
Engine oil pressure index gauge 13 is connected with engine oil pressure signaling line 14, be used to refer to the engine oil pressure of diesel engine, alarm pressure signaling line 15 is connected on the low pressure alarming lamp 16, when the engine oil pressure of diesel engine is lower than alarm pressure, warning light 16 is bright, the engine oil pressure of prompting driver motor is low, needs to detect and refuels.
As can be seen from Figure 1, the inner installation of automobile engine oil pressure transducer part is less, and assembling is simple.
As can be seen from Figure 1, do not have mechanical contact in the automobile engine oil pressure transducer total, the disadvantage one that has overcome traditional mechanical compression sensor has mechanical contact.
As can be seen from Figure 1, thick film pressure transducer chip 4 is experienced engine oil pressure with sensor body 1, seal ring 3 composition Seal cages.Thick film pressure transducer chip 4 has high temperature resistant, corrosion-resistant, high reliability features, thereby makes the automobile engine oil pressure transducer have high reliability features.
As can be seen from Figure 2, the ground wire of automobile engine oil pressure transducer body 1 links to each other with the ground wire of engine oil pressure index gauge 13, signaling line 14 is connected with engine oil pressure index gauge 13, alarming line 15 is connected with low pressure alarming lamp 16, connecting means and mechanical type oil pressure sensor are in full accord, can directly substitute the mechanical type oil pressure sensor and be installed on the diesel automobile engine.
