The ESD alarm is a device for detecting electrostatic discharge (ESD) events, and its principle is to determine whether an ESD event has occurred by detecting the electrostatic voltage in the environment.
When the electrostatic voltage exceeds a certain threshold, the ESD alarm will immediately emit an audible or optical signal to alert people to the possibility of an electrostatic discharge in order to avoid electrostatic damage to equipment and products.
ESD alarms typically use components such as piezoresistors, capacitive sensors or ionization chambers to detect static voltage. When the static voltage in the environment exceeds a set threshold, these components generate an electrical signal, which is amplified and processed to output an alarm signal that triggers the alarm to emit a sound or light signal.
ESD alarms are widely used in electronics, semiconductors, optics, medical devices, aerospace and other industries to safeguard electrostatic safety in the production process.
