PETROSTER PetroOPT ATEX sensors are optical sensors designed to detect leaks of liquid substances using dry or wet methods in systems of categories II, III and V, in accordance with EN 13160-1. Depending on the application, they can also be used as sensors for production processes and other utilities related to detecting changes in the liquid level, such as an overflow sensor. They are dedicated to work with PETROSTER control units, however, they are adapted to work with most available control units. They are equipped with a continuous cable monitoring system, in accordance with the requirements of PN-EN 13160-1, enabling the differentiation between an alarm related to a change in the sensor status and a damage to the sensor cable. They are optical sensors equipped with a measuring optical system used to detect liquids by changing the refraction of light after the optical element is immersed in the liquid or after its emergence, depending on the application. The unexcited state (not immersed in a liquid) causes a signal in the form of a voltage of approximately 4.5V, and a voltage below 1V occurs when the sensor is excited, i.e. when light is refracted by immersion in a liquid.
