Basic principles:
Torque measurement: using strain gauge electric logging technology, on the elastic axis of the strain bridge, to provide strain bridge power supply can be measured the electrical signals of the elastic axis is twisted.The strain signal amplification, after a voltage/frequency conversion, into frequency signal proportional to torsional strain.
The working process:
Special torque strain gauge with strain of adhesive post on the measured elastic shaft and strain bridge, to provide strain bridge power supply can be measured the electrical signals of the elastic axis is twisted.The strain signal amplification, after a voltage/frequency conversion, into frequency signal proportional to torsional strain.The energy input and the output signal of the system are borne by the gap between the two groups of special ring transformer, non-contact, therefore the energy and signal transmission function.
To provide sensor + 15 VDC power supply, the crystal oscillator in excitation circuit that produce 400 hz square-wave, after which produce ac excitation power supply, power amplifier through energy ring transformer T1 from the stillness of the primary coil to the rotation of the secondary coil, get on the ac power through the axis of rectifier filter circuit to get + 5 v dc power supply, the power supply do the work of operational amplifier power;Composed of benchmark power and double op-amp precision regulated power supply produce precision of + / - 4.5 V dc power supply, the power supply and power for bridge, there are seats amplifier power V/F converter work.
When it comes to elastic shaft torsion strain bridge detection of mV level of strain signal by instrumentation amplifier amplified into 1.5 v + / - 1 v strong signal, can be converted to frequency signal by v/F converter, through the ring transformer T2 signal from the rotation of the primary coil to static secondary coil, after the signal processing circuit of the sensor shell filter, plastic and elastic bearing can be affected by the torque is proportional to the frequency signal, the signal as TTL level, can provide special secondary instrument or frequency meter display, also can directly to send the computer processing.Because the rotating transformer dynamic - static only a fraction of mm space between the ring, combined with the sensor axis measurement part is sealed within a metal case, form effective shielding, therefore has a strong anti-interference ability.
The frequency of the sensor output signal in the zero to 10 KHZ, positive rotation when the full range of 15 KHZ, counter-rotating full scale for 5 KHZ, namely the number of variables in a full range of 5000 per second.Speed measurement using photoelectric measurement method of gear or magnetoelectric gear, shaft can produce 60 pulse not revolve, high or medium speed sampling can use the method of measuring frequency, low speed sampling can be used when the method of the measurement cycle.The sensor precision of plus or minus 0.2% (F.S).Due to the sensor output frequency signal, so no conversion can be directly sent to the computer for data processing.
Signal output and signal collection:
1. The torque signal output basic form:
Square wave signals, the pulse signal.
According to user needs to support the analog signal output voltage or current analog signal output.
2. The torque signal processing form:
Torque sensor output frequency signal to the frequency meter or digital form, directly read is proportional to the torque of the frequency signal or voltage and current signals.
The output torque of the torque sensor with frequency signal to microcontroller secondary instrument, directly display the real-time torque value power, rotational speed and RS232 communication signal.
Directly to the torque and rotating speed frequency signal to a computer or PLC for processing.
Maintenance:
1. Every year to increase torque sensor on both ends of the bearing grease.Add grease, only open the bearing cap on both ends, adding grease to the bearing, then cover the two end cover.
2. Should be stored in a dry, no corrosion, at room temperature was 20 ℃ -- 70 ℃.
Note:
1. When installation, can insert or pull out the air plug, do not knock, collision sensors directly.
2. The coupling of fastening bolts should be tightened, the outside of the coupling should add shield, to avoid personal injury.
3. The output signal lines shall not be over the ground, to the power supply circuit, the output current is not more than 10 ma, shielded cable shield must be connected to the public side of + 15 v power supply.
Install and use
1. The installation

2. The connection way (torque sensor and power equipment, the connection between the load equipment)
(1) as shown in figure 5 elastic dowel pin shaft coupling, and the connection mode of simple structure, easy processing, convenient maintenance.Able to trace the compensation caused by installation error axis relative offset, at the same time can have the effect of slight vibration.Suitable for medium load, frequent starting with high speed, the working temperature of 20-70 ℃

(2) the rigid coupling connection as shown in figure 6, the edge joint form of simple structure, low cost, no compensation performance, not cushion damping, the installation of two axis precision is higher.Used to working conditions of small vibration.

Installation requirements:
1. Torque sensor can be installed in horizontal or vertical installation.
2. The power devices, sensors, load should be installed on the solid foundation, in order to avoid excessive vibration, otherwise may be unstable data, reduce the accuracy of measurement, even damage the sensor.
3. Use elastic dowel pin shaft coupling or rigid shaft coupling.
4. The power devices, sensors, load axis coaxiality should be less than 0.05 mm phi.
