2008-09-18 - Zirconium dioxide sensors are capable of detecting small amounts of oxygen, down to measuring ranges of 0-1ppm.
ABB, the world leading power and automation technology group, today announced that it has rounded off its product range of measuring technologies for the EasyLine series of continuous gas analysers with the addition of the zirconium dioxide sensor ZO23. The Z023 sensor has for many years, only been associated with ABB's high-end Advance Optima analyser range.
Zirconium dioxide sensors are applied in the measurement of oxygen in pure gases, such as for air separation plants. They are capable of detecting small amounts of oxygen, down to measuring ranges of 0-1ppm. This makes the EasyLine analyser perfectly suitable for the quality control of technical gases in gas depots or for the monitoring of protective gas atmospheres. Due to the nature of the catalytically inactive cell, oxygen can be reliably measured even in the presence of small amounts of flammable gases.
The sensor exhibits a long operational lifespan with an internal function test (patent pending) which checks for the functionality of the cell during operation.
Measured values and status signals can be transmitted by means of digital interfaces such as Modbus connection and Profibus DP which are available for integration into a distributed control system or PLC.
