Longlv Electronics Longlv NJL-303 compact non-contact dynamic torque sensor rotating torque viscometer torque torque sensor

The torque sensor is a precision measuring instrument that measures various torques,rotational speeds and mechanical power. The application range is very wide,mainly used for: 1. Testing the output torque and power of rotating power equipment such as electric motors,engines,and internal combustion engines; 2. Testing the torque and power of fans,water pumps,gearboxes,and torque wrenches; 3. Railway locomotives,torque and power detection in automobiles,tractors,aircraft,ships,and machinery; 4. Can be used for torque and power detection in sewage treatment systems; 5. Can be used to manufacture viscometers; 6. Can be used in process industries and processes in industry.

baseprinciple

Measurement of torque: Using strain gauge electrical measurement technology,a strain bridge is formed on the elastic shaft,and the electrical signal of the elastic shaft torsion can be measured by providing power to the strain bridge. After the strain signal is amplified,it is converted into a frequency signal proportional to the torsional strain through voltage/frequency conversion.
