The performance characteristics of the threaded high-temperature zirconia oxygen sensor further enhance the convenience of users in the industrial field

Based on Zirconium dioxide (ZrO2), SST's oxygen sensor meets the performance specifications of the industry. By combining the oxygen ion pump sensing mechanism, the need for sealed reference gases and frequent calibration is eliminated, making the system more compact, easy to install, extending fault free life, and not depleting the sensor. The SST thread mounted zirconia oxygen sensor provides an easy to use solution where only the O2 sensor head itself is exposed to the sample gas environment. Therefore, all supporting electronic devices can stay away from potential hazards and ensure long-term reliable operation.

O2S-FR-T2-18C/B/A is a zirconia oxygen sensor, with a sensitive element of zirconia. It uses two zirconia discs and a sealed space in the middle. One of the functions of the tray is a reversible oxygen pump, which sequentially fills the sample gas and exhausts this small space. Another disk is used to measure the oxygen partial pressure difference ratio and obtain the corresponding sensing voltage. When the zirconia disk operates as an oxygen pump, the required temperature of 700 ° C is generated by the heating element. The time it takes for the oxygen pump to reach the rated low and high pressure within a small space range corresponds to the oxygen partial pressure value in the environment.

The device features an M18 x 1.5mm threaded mounting shell and a sturdy stainless steel structure that can withstand extreme temperature levels (from -100 ° C to 250 ° C). This makes it very suitable for combustion control, continuous emission monitoring systems, and accelerated composting applications in industrial coal/oil/gas/biomass boilers. Supports an oxygen pressure range of 2mbar to 3000mbar, with an accuracy of 5mbar and strong linearity throughout the entire temperature range. This sensor has a fast response time (<4 seconds) and covers oxygen concentrations ranging from 0.1% to 100%. To complement this sensor, SST provides the OXY-LC high-performance interface board, which includes all processing electronic devices required to meet specific application requirements and powers the sensor itself.
