Oxygen sensors

Product catalog summary
Overview: The document provides technical specifications and applications for the EXPLORER O2 series oxygen transmitters and sensors by RECOM INDUSTRIALE s.r.l. These devices are designed for use in ATEX 94/9/EC safety systems, naval applications, and harsh environments.
Specifications:
  • Detection Technology: Three sensor types are available: Electrochemical (0-30% vol), KE-25 Type (0-100% vol), and Zirconium Dioxide (0.1-100% vol).
  • Mechanical: The sensors are housed in die-cast aluminum or ABS plastic containers with ¾" NPT cable glands.
  • Electrical: Power supply ranges from 12-24 Vdc, with different power consumption for each sensor type.
  • User Interface: Internal 7-segment, 4-digit LCD display with three buttons for programming and service operations.
  • Operating Conditions: Temperature ranges from -20°C to +250°C, with humidity tolerance up to 95% relative humidity (non-condensing).
Applications: The sensors are suitable for workplace safety, measuring oxygen in high-temperature environments, and gas mixtures. They are approved for naval sector applications by RINA, MED, and ABS.
Performance:
  • Response Time: T90 response times vary from 4 to 15 seconds depending on the sensor type.
  • Sensor Life: Varies from 24 months to 10 years depending on the sensor and environment.
  • Calibration: All sensors require calibration with 100% N2.
Approvals: The sensors are approved for use in hazardous areas under ATEX II G Ex D IIC T6 Gb and have maritime approvals from RINA and MED.

Oxygen sensors-1

■ For ATEX 94/9/EC safety systems in Ex aluminum case for % NPT cable gland ■ For naval applications RINA - MED ■ For harsh environments and high temperatures ■ Complete set of accessories ■ Excellent value for money ■ High response speed The oxygen concentration is displayed in % volume. Depending on the application, three different sensors are available: The electrochemical sensor with a range of 0-30% vol, from the RTE series (enables continuous monitoring of oxygen in Exd classified areas, and is supplied with a watertight die-cast aluminium container according to ATEX specifications), the KE-25 type sensor for oxygen measurements up to 100% vol., in atmospheres rich in carbon dioxide (CO2) and the Zirconium dioxide sensor for oxygen measurements at high temperatures. The internal display, mounted on the Transmitter's PCB card, facilitates the periodic control procedures, verification and calibration, through the simple use of 3 keys. Sensors for flammable gas, oxygen, CO and H2S are approved for applications in the naval sector: RI.NA, MED and ABS Type approval. The transmitters are equipped with a special circuit that automatically compensates for the zero point drift. For the measurement in very hot environments or gas at high temperature, a special Zirconium dioxide (ZrO2) sensor is used. In this case the 4-20mA transmitter is contained in a plastic container, while the sensor is positioned at the end of a 1 m long cable, and the probe containing the sensitive element is available in 3 different lengths: 28, 45, 55 mm. /#S.
