the sensor is commonly used in bridge crane applications. We provide clamping sensors similar to DLWS for the end of crane wire ropes in order to measure the load without affecting the amount of headroom that the crane operator must use. These systems are usually used for limit switches to turn off cranes that are overloaded. This is done by using a small load cell controller with programmable setpoints. These devices turn on and off a smaller voltage, which is usually used as the logic for a larger relay that can turn off the power to the entire crane.

　　We also provide tension link load cells, such as CTL2 or DCL10, for use on crane hooks. These apps are simpler and easier to install but can cause headroom losses between 12" and a few feet. Some of these apps use wireless technology to transmit information to crane operators, ground crews, or one of our many. Provide wireless receiver for recording, analog output, serial output, printing, or relay output.

　　For certain applications where there are no dead ends and headroom is critical, load shackles are another effective solution. These functions are similar to trolley load cells, but save headroom at the cost of accuracy.

　　The simplest solution is to use a crane scale. Crane scales have begun to contain more functions than in previous years, but traditionally they are a simple S-shaped or double-ended shear beam installed in a housing with a display. They allow calibration and zeroing like other indicators. Some of these include wireless technology and removable batteries.

　　Example of the tension sensor

　　On the right is an example of the tension sensor being pulled apart instead of being bent or compressed. Imagine the force on the towing rope. The rope is under tension, as shown in the figure below. This is a good example of a tension sensor, which can measure the weight of a lifted load.

　　The working principle of the tension sensor used on the ship:

　　In the scale sensor, the strain gauge is arranged parallel to the load axis. When tension is applied, the wire assembly of the strain gauge becomes longer and thinner, thereby increasing electrical resistance. This change in resistance is proportional to the applied force so that the applied force can be determined.

　　scale sensor application

　　The scale sensor is used where it is necessary to measure tension, tension, traction, mooring, or other tension.
