Both measuring static torque, torque can be measured;
High precision, good stability, strong anti-interference ability;
Small size, light weight, easy to install;
Without continuous measurement can be repeated zero reverse torque;
Collecting ring with no wearing parts, high speed and long run;
Strain elastic strength, can carry 150% load;
Anywhere installation in any direction;
Sensor part from the second instrument independently, directly with the measuring Board and torque measuring device consisting of PLC or DCS.Explosion-proof torque sensor installation requirements:
1. the sensor shaft diameter and the Center is high.
2. using two sets of couplings, torque sensors installed between the power source and the load.
3. the sensor can be operated by a rigid or flexible coupling connections. Vibration is large, concentric 0.2mm is greater than 0.05mm, suggested the use of elastic coupling, install coaxial degree of more than 0.2mm, is strictly prohibited.
4. reliable power and load equipment must be fixed to avoid vibrations.
5. the torque signal sensor base and the base of the equipment reliable and avoid bending moments.
6. standard sensors whether horizontal or vertical installation, excess axial force on the sensor is not allowed, bending, or affect the use of sensors, even resulting in damage to the sensor.
7, read the onboard product manual carefully before installation. Explosion-proof torque sensor signal processing:
1. use the ZRN500 series torque torque values are displayed directly;
2. torque frequency signal is sent to your computer or directly to PLD;
3. converted by 4-20m a or 1 to 5V analog signals. (Optional)
Precautions for use:
1. explosion-proof torque sensor wiring must be correct;
2. the range of ± 15V: shall not be less than ± 14.5V shall not exceed ± 15.5V;
3. the output signal lines is allowed to, upon the power supply circuit, the output current is less than 10mA;
4. shield cable shielding must be ± 15V power supply common Terminal (GND) connection.
5. If you have any questions please feel free to contact our company, within the warranty period shall not disassemble.
