Dynamic torque transducers can be used in the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches, which have the advantages of high precision, fast frequency response, good reliability and long life.
Installation process:
1. According to the connection form of the shaft and the length of the dynamic torque sensor, determine the interval between the prime mover and the load, adjust the separation of the axis of the prime mover and the load relative to the reference plane, so that the coaxiality of their axis is less than Φ 0.03mm, and fix the prime mover and the load on the reference plane.
2. Separate the couplings into their respective shafts.
3. Adjust the interval between the dynamic torque sensor and the reference plane, so that the coaxiality between its axis and the axis of the prime mover and the load is less than Φ 0.03mm, and fix the dynamic torque sensor on the reference plane.
4. Tighten the coupling and the device is finished.
Maintenance & Maintenance:
1. Grease the bearings at both ends of the dynamic torque sensor every other year. When grease, only the two-end bearing covers are opened, grease is added to the bearings, and the two-head covers are attached.
2. It should be stored in a dry, non-corrosive, room temperature of -20°C--70°C.
Notes:
1. When the device is installed, it cannot be operated with electricity, and do not directly knock or bump the sensor.
2. The fastening bolts of the coupling should be tightened, and a protective cover should be added to the outside of the coupling to prevent personal injury.
3. The output of the signal line shall not be to the ground, short circuit to the power supply, and the output current shall not be greater than 10mA? It is necessary that the shield of the shielded cable is connected to the common end of the +15V power supply (power ground).
Device application:
1. Application environment: The dynamic torque sensor should be installed in an environment with an ambient temperature of 0°C - 60°C, a relative humidity of less than 90%, and no flammable and explosive products. It should not be installed in an environment with strong electromagnetic interference.
2. Device method:
(1) Horizontal device:
(2) Straight device:
3. Connection method: The connection between the dynamic torque sensor and the power equipment and load equipment
(1) Elastic pin coupling connection, this connection method is simple in structure, simple in processing, and convenient in maintenance. The relative deviation of the shaft caused by device errors can be compensated for slightly, and together with the effect of subtle vibration reduction. It is suitable for medium load, high and low speed working occasions with frequent starting, and the working temperature is -20-70°C.
(2) Rigid coupling connection, this connection form has simple structure, low cost, no compensation performance, can not buffer and dampen vibration, and has high precision for the device of two axes. It is used in operating conditions with very low vibrations.
4. Device requirements:
(1) The dynamic torque sensor can be installed horizontally or straightly.
(2) Power equipment, sensors, and load equipment should be installed on a solid foundation to prevent excessive vibration, otherwise data instability may occur, measurement accuracy may be reduced, and even damage to the sensor.
(3) Choose elastic pin coupling or rigid coupling.
(4) The concentricity of the axis of the power equipment, sensor and load equipment should be less than Φ0.05mm.

Precautions for the use of gas flow meters - Autonex
1. When the working conditions of the exterior are changed (such as changing the medium, changing the ambient temperature, etc.), the zero position of the exterior should be adjusted from the beginning. At the same time, the outer surface of the catheter must be leveled and calibrated with a spirit level. Failure to do so will increase the effect of the change in operating conditions on the zero drift. Rack ...
