Michell Instruments XZR200 oxygen analyser
Michell Instruments has extended its range of oxygen analysers with the introduction of the compact XZR200 oxygen analyser.
According to the company, it is capable of measuring percentage oxygen to better than 1% of span (or 0.5% O2) with ranges of 0-25% and 0-100% available. The analyser is easy to install and integrate into existing systems as no specialist software is required; the RS232 output can be accessed via a PC.
The analyser offers four configuration options, with two choices of probe length and two temperature ranges. The lower temperature range (up to +25°C) is suitable for relatively low-temperature applications such as food and drink packaging, while the higher temperature range of up to +400°C serves combustion control and metal treatment applications.
Depending on the application, the analyser may also be configured to measure in either 0-25% or 0-100% oxygen concentrations. The first configuration gives the highest accuracy of 0.5% O2 in the combustion process range. In the 0-100% range the accuracy is 1% O2.
A 3.3 V DC logic output is used to monitor the sensor for diagnostic purposes. It is a way of listening to the sensor’s ‘heartbeat’ and enables the operator to check on the health of the sensor, providing a warning if there is a fault with the sensor. The life span of the zirconium dioxide sensor is between 1 and 7 years, depending on the temperature and type of gas measured.
