PETROSTER PetroVAP ATEX sensors are vapor sensors designed to detect leaks of liquid substances or gases using the dry method in category III and V systems, in accordance with EN 13160-1. They are intended mainly for the detection of hydrocarbon vapors, including gasoline, diesel oil, LPG, alcohol, hydrogen and carbon monoxide, as well as other media depending on their physicochemical properties and volatility. They are catalytic combustion sensors with high sensitivity and short response time, using the phenomenon of changing the sensor's output resistance depending on the number of vapor particles in the vicinity of the sensor. The output voltage from the sensor increases in proportion to the increase in the detected vapor concentration, ranging from 0.2V at the neutral state to 5.5V when the maximum detection threshold of the sensor is reached. The sensors have a built-in diode in the body, signaling the active power supply of the sensor and the excitation level, changing the color of the diode in proportion to the increase in the detected vapor concentration, from green in the neutral state to red when the upper threshold of the detection range is reached.
