How PID Sensors Work

The functionality of PID sensors hinges on the principle of photoionization, a process where ultraviolet (UV) light is used to ionize molecules of gas. When a VOC passes through the sensor’s chamber, it is exposed to UV light, leading to the ejection of an electron from the molecule. This creates a positively charged ion and a free electron. The electric current produced by the movement of these ions and electrons towards the electrodes is proportional to the concentration of VOCs, allowing the device to quantify the amount present.

This method’s sensitivity is largely determined by the energy of the UV lamp used; the higher the photon energy, the broader the range of compounds that can be ionized and detected. This is why PID sensors are equipped with lamps of varying energies, tailored to the specific needs of the monitoring task at hand. The precise, real-time data provided by PID technology is invaluable for environmental professionals seeking to quickly assess and respond to VOC presence, ensuring the safety and health of both the environment and the public.
