To measure the torque is to use the related electrical measurement technology of the strain gauge to form a strain bridge on the elastic shaft. If power is supplied to the strain bridge, the electrical signal of the torque received by the elastic shaft can be measured.After the strain signal is amplified by a certain device, and then through the pressure/frequency conversion, it can be converted into a frequency signal proportional to the torsion strain.Dynamic torque sensor can measure a variety of different mechanical power, speed and torque measuring devices.It is used in a wide range of fields, and is generally used in the following areas: applied in process industry and process industry; in sewage treatment systems, measuring related power and torque; measuring the power of aircraft, ships, railway locomotives, mining and other machinery And torque; can be used to make viscometers; measure the output power and torque of related devices such as internal combustion engines and engines; measure the power and torque of torque wrenches and water pumps.
The relevant characteristics of the dynamic torque sensor are: 0. Its measuring range is the standard optional 10000-5Nm, and the non-standard customizable 10 Nm, 20 Nm, 100 Nm, XNUMX million Nm, etc., this is Special range.Two: Its volume is very small, and the heavy sensor can be used separately from the secondary instrument. It only needs to provide a certain power supply.It is very light and very easy to install.Three: Both static and dynamic torque can be measured.Four: The positive and negative torque can be measured continuously, and there is no need to adjust the zero and re-measure after each measurement, which brings great convenience to multiple measurements.Five: It has very good stability, high precision, and anti-interference performance is also very good.Six: The output signal can be pulse wave or waveform-square wave, whichever is easy to handle.
The matters needing attention when installing and using dynamic torque sensor are:
1. The environment during installation should be controlled at 0℃ to 60℃, and the relative humidity should be controlled below 90%, and the installation environment must not contain explosive and flammable materials.In order to enable the sensor to be used safely and without interference, do not install it in a place with strong electromagnetic interference.
2. The signal line cannot be grounded when it is output, because this will cause a short circuit of the power supply. The shielding surface of the shielded cable must be connected to the common end of the +15V power supply, and the output current should be less than 10mA.
3. The fastening bolts of the coupling should be tightened. For the safety of everyone's life, a protective cover must be added to the outside of it.
4. Do not install the sensor when it is electrified, and don't bump or knock the sensor directly.
When installing the dynamic torque sensor, there are the following requirements: The sensor can be installed vertically or horizontally, and you can choose any; the concentricity of the load equipment, the sensor and the power equipment axis should be less than Φ0.05mm; in order to prevent too much vibration, Therefore, it is recommended that load equipment, sensors and power equipment should be installed on a fixed basis, otherwise, the accuracy of the sensor measurement is likely to be reduced, and the measured data is not stable enough, not representative, and if the situation is serious, it will be damaged. Sensor; when connecting, use a rigid coupling or an elastic pin coupling.
Matters needing attention when maintaining and repairing the dynamic torque sensor: The sensor should be stored in a place that is not corrosive, dry, and the indoor temperature range is -20°C-70°C; Add a proper amount of grease to the bearings. When adding, you only need to open the covers of the bearings at both ends, then add the grease, and finally cover the covers at both ends.
