Fire prevention BEST Oxygen sensor
The O2 Sensor controls the PermaPrevent® System. The amperometric Sensor is based on a cirkonia electrolyte cell. The Sensor is equipped with 4 programmable potential free contacts (programmable with optional software) and one contact for system fault. NO calibration gas needed. Calibration via USB and software.
All system information is shown in the high resolution OLED display. An integrated Data-Logger safes data over a period of more than 2 years on a SD-memory card. The information can be read as a *.csv file directly in Microsoft Excel or other adequate programs. Network connections between Sensors are integrated. One Sensor is working as MAIN the others are working as SLAVE Sensors. Equipped with two CAT5 connection points, allowing connection for more than one OLED Display.
The programming will be made with the BEST-O2-Tool via USB. The OLED technology consumes excessively low current however good legibly in daylight conditions . No backlight needed. The status of the relays are also shown on the display, presenting a good overview of the system status.
• Wide measuring range from 0,1 to 25% Oxygen
• High accuracy of about 0,1%
• No ambient temperature sensitivity
• Low cross sensitivity
• Long service life
• Single point calibration
• Time to start (heating) > 1 min
• Connectivity via network

Display
Designed for continuously display of the O2-Concentration within a PermaPrevent® atmosphere. Connected vie CAT5 Network cable to the O2 Sensor, mounted near the entrance door of the protected room.
The high-resolution OLED-display and the high brightness makes the figures very well readable. An integrated data logger saves the values up to two years on a SD-memory-card. These values are readable on a CSV file . The cabling of the display is a standard CAT5-wiring from the Sensor. The feed line is supervised by an integrated broken wire and short cut sensor. The OLED technology consumes excessively low current however good legibly in daylight conditions. The status of the relays are also shown on the display. Hence, the display informs continuously about the status of the sensor outside of the room as well.
