product description 

Housing Extension Sensor Assembly (dc) is a special product that is commonly used to measure and 

monitor changes in the housing size of machinery or equipment. This assembly can be used for a variety 

of applications, such as monitoring the vibration, temperature, pressure and other parameters of the 

machine to ensure its proper operation and prevent potential failures.

The special feature of the housing Extension Sensor Assembly (dc) is its ability to accurately measure 

changes in housing size and convert them into readable electrical signals. This type of assembly typically 

has high precision and sensitivity that accurately reflects changes in the size of the housing, providing 

engineers and operators with important information about the state of the machine.

Housing extension sensors typically use a technique called a strain gauge to measure dimensional changes 

in the housing. A strain gauge is a sensor that measures small deformation on the surface of an object, usually 

consisting of a thin strip of metal or plastic whose resistance changes with the deformation.

In a housing extension sensor, the strain gauge is pasted or fixed to the housing surface to be measured. When 

the shell deforms, the strain gauge also deforms accordingly, resulting in a change in its resistance value. This 

change in resistance value can be measured and converted into the corresponding electrical output, which reflects 

the change in housing size.

Under normal circumstances, the shell extension sensor will be used with some additional electronic equipment, 

such as signal amplifiers, data collectors, etc., in order to amplify, filter, digitize and other processing of the 

measurement signal to improve the accuracy and reliability of the measurement. At the same time, in order to ensure 

the accuracy of the measurement, the housing expansion sensor also needs to be calibrated and maintained regularly.
