Wheel Loader

It is a very good portable weighing instrument, 4 weighing instruments can work at the same time and connected to an external display, which can measure and display the weight of a single wheel, axle weight and the whole vehicle at the same time. At the same time, the wheel can be accurately measured without centering on the weighing plate, which is convenient and quick.

The features of the whole set of equipment are:

◆ The measurement results are very accurate;

◆ Light weight, one person can operate and use;

◆ High protection level, good reliability, can be overloaded.

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.

Main features:

For 16 channels, four slaves, each slave with 3 thermocouple channels, 1 air pressure measurement channel;

The air pressure measurement accuracy error is 0.015kpa;

Temperature measurement accuracy error 0.05%FS;

Each channel has internal cold junction compensation;

The air pressure and temperature of the detection point are sent to the receiving end wirelessly, and the CAN message is output.

Wireless wheel speed sensor

Wireless wheel speed sensor

The system is an innovative system for wirelessly measuring wheel speed and temperature without any additional mechanical connection. The system does not require a stator or additional reference points and provides measurements on test benches and outdoors, even in harsh conditions such as mud, snow and dust. The linearity of the device is typically 0.2% better. Impact on the axle also does not affect the results, fully supporting various wheel speed tests under the vehicle's dynamic performance.

The system includes four measuring modules and one receiving module. The measurement module has a built-in speed sensor, a three-channel temperature measurement module, a rechargeable battery, and a wireless transmission module. The sensor can directly obtain the wheel speed and wheel temperature on the wheel by fixing the wheel screw. The transmission protocol of the receiving module is 2.4G, and the signal and temperature of four wireless measurement modules are simultaneously received and output through the CAN protocol.

Main features:

Each system includes 4 wheel speed sensor slaves, and each slave includes 1 wheel speed measurement channel and 3 temperature channels;

Support up to ±7200 RPM;

Accuracy＜0.3 % at 0℃ to 50℃;

5. The temperature of the detection point is sent to the receiving end wirelessly, and the CAN message is output.

Low Profile Pedal Force Sensor

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;
