Description
Technical field
The utility model relates to a kind of simulated automotive engine water temperature sensor experimental stand.
Background technology
The automobile engine water temperature sensor is a very important sensor on the electronic automobile engine.Its effect is the water temperature by detection of engine, to revising the distributive value and the duration of ignition of engine.Its detection mode is a thermistor-type, generally adopts the thermistor of negative temperature coefficient, and when temperature raises, its resistance descends, and the variation by resistance becomes electric signal and flows to Engine ECU.
The utility model content
The utility model purpose is to provide a kind of simulated automotive engine water temperature sensor experimental stand at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model simulated automotive engine water temperature sensor experimental stand, comprise accumulator 1, switch 2, voltage stabilizer 3, resistance 4, adjustable resistance 5 and voltage table 6, wherein connect the input end of voltage stabilizer 3 behind the positive pole of the accumulator 1 serial connection switch 2, connect the input end of adjustable resistance 5 and voltage table 6 behind the output terminal series resistor 4 of voltage stabilizer 3 respectively, adjustable resistance 5 is connected ground connection with the output terminal of voltage table 6.
Described resistance 4 is precision resistance, and resistance is 1500 Ω.
The utility model simulated automotive engine water temperature sensor experimental stand is simple in structure, is easy to realize.
Description of drawings
Fig. 1: simulated automotive engine water temperature sensor experimental stand schematic diagram.
Embodiment
As shown in Figure 1, this experimental stand comprises accumulator 1, switch 2, voltage stabilizer 3, resistance 4, adjustable resistance 5, voltage table 6, voltage stabilizer 3 provides the DC voltage of 5V, resistance 4 is a precision resistance, and resistance is about 1500 Ω, and adjustable resistance 5 simulation water temperatures change, its resistance value adjusting scope is 200 Ω～30000 Ω, corresponding temperature range is 100 ℃～-20 ℃, and promptly temperature raises, and resistance value reduces.
By the variation that the resistance of regulating adjustable resistance 5 is simulated water temperature, the voltage that is added in adjustable resistance 5 two ends promptly changes, and this is the signal voltage of cooling-water temperature sensor, shows by voltage table 6.Turn right and stir adjustable resistance 5, the expression water temperature raises, and signal voltage descends; Otherwise, then rise.Signal voltage range is 0.5V～4.8V.
