Until now, I was concerned about Mechanical, but Digital ratchet purchased Torque in an attractive way to see it visually.
The measurement range is 2 to 30 N - Standards commonly used for m and Maintenance.
Accuracy meets international standards, operation method is also simple! Usage impression is the same as ordinary Ratchet wrench!
Large miscellaneous, but I tried collecting about Torque wrench, so it would be great if you could refer.
Axial forces are set for screw parts at the design stage, but because measurement of axial force requires special measuring instruments and equipment, tightening control by Torque is performed instead.
Torque wrench is used to prevent variations due to individual differences in loosening, breakage, and tightening.
Torque wrench is classified into Signal formula Torque wrench and direct read type Torque wrench depending on shape and structure.
Signal formula Torque wrench is set up Torque to be tightened first, and it is a mechanism to know that Torque has been reached by tightening with the feel and sound like Pushing. In addition, there are no graduations in the Pre-set type and Body type which can change Torque can be changed with Body's scale, Torque wrench testeretc. There is something that is necessary.
Direct read Torque wrench reads the loaded Torque with scale. Quantity : Pair (for Left and Right) Most of them can be measured in either case, some have a Peak hold mechanism. Torque detects by the deflection of Beam and reads the scale of Body.
Digital formula Torque wrench detects Torque at the sensor and reads the displayed Torque.
Usage is differentiated by the task of tightening the screw with the prescribed Torque and the work of measuring the tightening Torque of the tightened screw for inspection purpose.
Tighten the screw with the specified Torque "Torque wrench for work" Or measure the Torque of a tightened screw "Torque wrench for measurement" I call it.
Torque wrench has a measurement range defined, and beyond the use Torque will cause damage, so be careful.
In addition, precision will be out of order before it is handled as cluttered, so care must be taken not only during use but also after storage after storage.
Also, regular inspection - To perform calibration is also indispensable for maintaining accuracy.
Incidentally, in Japan FOR JAPAN MODEL, we used the weighing method to calculate Torque wrench (Including double scale) Sales are generally prohibited in principle.
