Tension sensor detection method

Tension sensors have very important applications in many areas of people's daily life. Everyone must pay attention to ensure that the tension sensor can work normally during the application process. The following is a small series to introduce the detection method of the tension sensor.

The detection methods commonly used for machine faults of tension sensors are voltage method, resistance method, short circuit method, open circuit method and current method.

Voltage method

The method of measuring the voltage value of a certain point on the line by the meter to determine the range of the electrical fault point of the machine tool or the component fault is called voltage method or voltage measurement method.

2. Resistance method

The method of using the meter to measure the on/off of a point or a component on a line to determine the point of failure is called the resistance method.

3. Short circuit method

Temporarily short-circuit a certain level of circuit or component suspected of failure, and observe whether there is any change in the fault state to determine the fault location. When the short circuit method is used to check the multi-stage circuit, short-circuit a certain service, the fault disappears or is significantly reduced, indicating that the fault is before the short-circuit point, and the fault does not change after the short-circuit point. If the output of a certain stage is not normal, the input end of the stage is short-circuited. If the output potential is normal, the circuit of this stage is normal. The short-circuit method is also commonly used to check whether the components are normal. For example, the base and emitter of the crystal triode are short-circuited with tweezers, and the change of the collector voltage is observed to determine whether the tube has amplification. In the TTL digital integrated circuit, the short circuit method is used to judge whether the gate circuit and the trigger can work normally. The thyristor control electrode and the cathode are short-circuited to determine whether the thyristor is inoperative or the like. In addition, some instruments (such as electronic potentiometer) input terminals can be short-circuited, and the meter indicates changes to determine whether the meter is interfered.

4. Open circuit method

In the inspection of the machine tool circuit, sometimes in order to detect special needs, the circuit must be disconnected for inspection. This method is called the open circuit method.

5. Current method

The method of determining the point of failure by measuring whether the current through a line is normal is called the current method.
