What is the function of the throttle orientation sensor?
The primary function of the throttle azimuth sensor is to detect whether the starting motor is in the idle condition or the load condition, and whether it is in the acceleration condition or the deceleration condition. The shaft of the resistor is linked to the throttle, and it has two contacts: a fully open contact and an idle contact. When the throttle is in the idle position, the idle contact is closed, and the idle condition signal is output to the computer. When the throttle is in other directions, the idle contact is opened, and the voltage signal is output relative to the different angles of the throttle, and the computer will identify the load of the engine according to the signal voltage value; According to the change rate of signal voltage in a certain period of time, it is determined whether it is an accelerated working condition or a deceleration working condition. Based on this information, the computer corrects the amount of fuel injected and may perform oil cut-off control.
Where is the throttle orientation sensor installed?
The throttle orientation sensor is mounted on the throttle body, and the sub-throttle orientation sensor is mounted on the sub-throttle. Common types are switched (contact) throttle orientation sensors, linear (potentiometer) throttle orientation sensors, and integrated throttle orientation sensors. The throttle orientation sensors used in the new intelligent electronic throttle control system are commonly available in two types: dual slip resistive and linear double Hall. If it is classified according to whether it can be adjusted, it can be divided into adjustable throttle orientation sensor and non-adjustable throttle orientation sensor. The holes of the set screws for the adjustable throttle orientation sensor are oval, and the loose set screw allows the orientation of the throttle orientation sensor to be adjusted to a small extent
What happens when the throttle azimuth sensor is broken?
The engine idle speed is not working normally (such as idle speed is too high or too low, idle speed is unstable, idle speed is easy to stall) or the engine acceleration is abnormal (engine shaking when accelerating, acceleration reaction lag, etc.), sometimes it will also lead to intermittent engine shaking in work.

The role and classification of safety barriers
In electrical intrinsic safety explosion-proof (abbreviation: intrinsically safe explosion-proof), we generally divide the workplace into explosion-proof area and non-explosion-proof area. There is the transmission of electrical energy between the explosion-proof area and the non-explosion-proof area, for example, the switches, buttons, sensors, etc. in the explosion-proof area are connected to the non-explosion-proof area through the wires.

Zero drift of high-frequency pressure sensors – we are blessed
There are several reasons for the formation of zero drift of high-frequency pressure sensors:
1. There are bubbles or impurities in the adhesive layer of the strain gauge
2. The function of the strain gauge itself is unstable
3. There are virtual solder joints in the circuit
4. The stress release of elastomers is incomplete; In addition to the magnetic field, ...

Troubleshooting for coding problems
P+F encoders are devices that compile signals (e.g. bit streams) or data and convert them into signals that can be communicated, transmitted, and stored. The P+F encoder converts angular or linear displacements, the former known as the code disc and the latter into an electrical signal. Therefore, the phenomenon: 1, ...

A little bit about photoelectric sensors – a blessing
Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...
