Capacitive Electric Torque Wrench164

A capacitive electric torque wrench is a type of torque wrench that uses a capacitor to measure the torque applied. This type of torque wrench is often used in applications where precision and accuracy are critical, such as in the assembly of precision machinery or in the calibration of other torque wrenches.

Capacitive electric torque wrenches work by measuring the change in capacitance between two plates. As the torque is applied, the plates move closer together, which increases the capacitance. This change in capacitance is then converted into a voltage signal, which is used to calculate the torque.

Capacitive electric torque wrenches offer a number of advantages over other types of torque wrenches. First, they are very accurate and precise. Second, they are not affected by changes in temperature or humidity. Third, they are easy to use and require minimal maintenance.

However, capacitive electric torque wrenches also have some disadvantages. First, they are more expensive than other types of torque wrenches. Second, they can be damaged if they are dropped or subjected to excessive shock.

Overall, capacitive electric torque wrenches are a good choice for applications where precision and accuracy are critical. They are accurate, precise, and easy to use. However, they are more expensive than other types of torque wrenches and can be damaged if they are not handled properly.

How to Choose a Capacitive Electric Torque Wrench

When choosing a capacitive electric torque wrench, there are a number of factors to consider. These factors include:
Accuracy: The accuracy of a torque wrench is determined by the amount of error that is introduced into the measurement. The accuracy of capacitive electric torque wrenches is typically expressed as a percentage of the full-scale reading. For example, a torque wrench with an accuracy of ±2% will have a maximum error of 2% of the full-scale reading.
Precision: The precision of a torque wrench is determined by the amount of variation in the measurement. The precision of capacitive electric torque wrenches is typically expressed as a percentage of the full-scale reading. For example, a torque wrench with a precision of ±1% will have a maximum variation of 1% of the full-scale reading.
Range: The range of a torque wrench is the minimum and maximum torque that it can measure. The range of capacitive electric torque wrenches is typically expressed in newton-meters (Nm) or pound-feet (lb-ft).
Resolution: The resolution of a torque wrench is the smallest increment of torque that it can measure. The resolution of capacitive electric torque wrenches is typically expressed in newton-meters (Nm) or pound-feet (lb-ft).
Features: Capacitive electric torque wrenches can come with a variety of features, such as data logging, peak hold, and preset torque settings. These features can be useful for certain applications.

Once you have considered these factors, you can choose a capacitive electric torque wrench that meets your needs.

How to Use a Capacitive Electric Torque Wrench

To use a capacitive electric torque wrench, follow these steps:
Select the correct torque setting. The correct torque setting will depend on the application. Refer to the manufacturer's instructions for the recommended torque setting.
Attach the socket to the torque wrench. The socket should be the correct size for the fastener that you are tightening.
Place the socket on the fastener. Make sure that the socket is seated properly.
Apply torque until the wrench clicks. The wrench will click when the desired torque has been reached.
Release the torque. Once the wrench has clicked, release the torque and remove the socket from the fastener.

Capacitive electric torque wrenches are easy to use and can help you to ensure that you are tightening fasteners to the correct torque.
