Description
Technical field
The utility model relates to the pressure sensor device with temperature sensor.
Background technology
At present, this sensor is used for detecting the pressure and temperature of inlet manifold in vehicle, and the engine of vehicle is based on the signal that characterizes these measured values and comes in check.The pressure detection integrated circuit is arranged in the sensor housing, comprising the pressure sensor that is used for detected pressures, pressure sensor is electrically connected to outer treatment circuit in terminal, detects pressure in the inlet manifold by air intake opening, and the pressure signal that measures is outputed in the external circuit.At present, automobile is also inequality at the pressure sensitive unit of different automobile types with temperature and pressure transmitter, and significant limitation is arranged, and sensing unit is subject to external interference.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of simple in structure, reasonable in design, able to programme, temperature and pressure transmitter with anti-interference and short-circuit protection function is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: have air intake opening on the end cap, adjustable pressure sensing chip IC is installed on the air intake opening, 3 pin of adjustable pressure sensing chip IC join through the data-interface of terminal and regulator, 2 pin of adjustable pressure sensing chip IC, 4 pin join the other end ground connection of capacitor C 1, C2 with the end of capacitor C 1, C2 respectively.

Fig. 2 is adjustable pressure sensing chip IC and regulator, capacitor C 1, C2 connection diagram;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is to have air intake opening 7 on the end cap 5, adjustable pressure sensing chip IC 1 is installed on the air intake opening 7,3 pin of adjustable pressure sensing chip IC 1 join through the data-interface of terminal 8 with regulator 2,2 pin of adjustable pressure sensing chip IC 1,4 pin join with the end of capacitor C 1, C2 respectively, other end ground connection.
The principle of work of this sensor is: (1) pressure portion: the adjustable pressure sensing chip is the silicon chip that adopts semi-conductive piezoelectric effect to make, and the one side of silicon chip is a negative pressuren zone, the another side effect be air-distributor pressure.Under the effect of gaseous tension, silicon chip will produce distortion in inlet manifold, and the resistance value of silicon chip is changed, thereby bridge voltage is changed.Because this voltage is very little, so after by hydrid integrated circuit this signal being carried out processing and amplifying in the circuit, just offer microcomputer circuit.When pressure regulating unit is regulated, only need pressure adjustment assembly is linked to each other with terminal, the parameter that changes the adjustable pressure sensing chip just can obtain required parameter value.(2) temperature section: because thermistor is the element that constitutes by to the highstrung semiconductor ceramics matter of temperature working body, this sensor uses NTC type thermistor, when intake air temperature is low, the resistance value of thermistor is big, the signal voltage height of sensor input microprocessor (ECU), microprocessor (ECU) control engine increases distributive value, otherwise then reduces distributive value.20 ℃ of precision of this thermistor are 2%, have improved the validity of measurement result greatly.
Claims (1)
1. automobile temperature and pressure transmitter, comprise that adjustable pressure sensing chip IC (1) and regulator (2) join, temperature sensor (4) is housed in the housing (3), rubber ring (6) is installed on the end cap (5), it is characterized in that: have air intake opening (7) on the end cap (5), adjustable pressure sensing chip IC (1) is installed on the air intake opening (7), 3 pin of adjustable pressure sensing chip IC (1) join through the data-interface of terminal (8) with regulator (2), 2 pin of adjustable pressure sensing chip IC (1), 4 pin respectively with capacitor C 1, the end of C2 joins, capacitor C 1, the other end ground connection of C2.
