Shock sensors are specifically engineered to detect and promptly respond to sudden changes in acceleration. These sensors primarily operate using piezoelectric principles, which generate electrical charges in response to mechanical stress. Several key characteristics define the performance and functionality of shock sensors, including sensor type, sensing range, sensitivity, and mounting type.
Sensor Types: There are two primary sensor types utilized in shock sensors: ball and vibration (Piezo film). Ball sensors utilize a small metal ball that moves within a conductive housing, generating electrical signals when subjected to accelerative forces. Vibration sensors employ Piezo film, which generates electrical charges when deformed by vibrations or shocks.
Sensing Range: The sensing range of shock sensors refers to the extent of acceleration they are capable of detecting. This range typically spans from 0 to 1500 G, with G representing the acceleration due to gravity.
Sensitivity: Sensitivity measures the magnitude of electrical charge or voltage produced by the shock sensor in response to a given acceleration. Sensitivity is expressed in units of charge per unit of acceleration (pC/G) or millivolts per unit of acceleration (mV/G). The available sensitivities for shock sensors vary and include options such as 0.055 pC/G, 0.09 pC/G, 0.350 pC/G, 0.608 pC/G, 0.840 pC/G, or 1 mV/G.
Mounting Type: The mounting type refers to the manner in which the shock sensor is installed or attached to the system or equipment being monitored. Common mounting options include screw mount, adhesive mount, or surface mount, allowing for flexibility in installation based on the specific application requirements.
In summary, shock sensors are specialized devices designed to detect and respond to sudden changes in acceleration. They utilize piezoelectric principles and offer various characteristics such as sensor type (ball or vibration), sensing range (0 to 1500 G), sensitivity (expressed in pC/G or mV/G), and mounting type (screw mount, adhesive mount, or surface mount). These features enable shock sensors to accurately measure and monitor accelerations in different industrial applications.
