Sensors and Leak Detection Systems

Leak detection system Sens8®

Sens8 is a modern, easy-to-use and reliable leak detection control unit, supporting up to 8 sensors of various types. It is an industrial solution that combines proven solutions resulting from the company's many years of experience with a modern approach. The control unit has an intuitive button where you can read the status of each sensor and a button to clear the alarm sound signal. The programming of the control unit and the graphical preview of indications and parameters is done via a dedicated Android application with safe Bluetooth® communication. It has 8 programmable potential-free relay outputs and optional GSM or Modbus communication, so it can also be used as an automation and indication system for any processes that require reading the status of sensors.

It has a closed, self-extinguishing polycarbonate housing with IP66/68 tightness class, alarm history, sensor auto-calibration function, the ability to programmatically change the sensor state, a cable continuity detection system and an application menu in Polish and English. The control unit works with Petroster sensors and many sensors from other manufacturers, such as OPW, VeederRoot and others. It has ATEX JSHP 18ATEX0021X of the highest explosion group II (1) G [Ex ia Ga] IIC.

Optical sensor PetroOpt® ATEX

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.

Vapour detection sensor PetroVap® ATEX

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.
