Tire temperature tire pressure sensor


Tire temperature and tire pressure sensor is a device that can detect tire pressure and temperature in real time. This device provides 1 high-precision air pressure sensor for detecting the air pressure of the tire, and 3 high-precision temperature measurement channels for collecting the temperature of the tire, and the measurement data of the device is output through the CAN interface. This device has a built-in large-capacity battery. It is easy to use without removing the battery when using it. It also has a remaining power prompt function, which avoids the user's trouble due to inability to estimate the use time because he does not know how much power is left, thus affecting the test results.

Low Profile Pedal Force Sensor

配套传感器13.jpg

SENBR1 pedal force sensor is used for pedal load test. Its shape design allows the sensor to be easily mounted on any vehicle pedal or fatigue/durability test bench.

Since the force on the accelerator and clutch pedals varies from small cars to heavy trucks, we offer different measurement ranges from 200N to 2000N. With the internal mechanical decoupling design, the accuracy is 1%FS for different applied force point positions. In addition, a portable and compact handheld display is optional, which is convenient for real-time observation of test values, and the measurement data can be output to the data acquisition equipment through the CAN protocol or analog signal.



Main features:

1. 200 to 2000 N range;

2. Minimum nonlinearity and hysteresis ≤ 0.1%;

3. Ultra-light aluminum alloy material;

4. Low sensitivity to eccentric load<1.0%;

5. Use the attached tape to fix it to the car pedal;

6. Portable and compact handheld display;

7. Applicable to accelerator pedal, brake pedal and clutch pedal.
