Oxygen Measurements at % Level: for SIL Applications

The PMA30 provides fast, accurate and reliable oxygen measurement in a 19" cassette. It has a SIL rating according EN61508 and includes an integral flow alarm. There are two possible configurations: 1. PMA30A/D has a combined analogue/digital meter 2. PMA30/D has only a digital meter Paramagnetism is significantly higher for oxygen than other common gases. The M&C magneto-dynamic measurement cell uses this physical phenomenon to provide the most accurate and reliable measurements available. Improved speed of response is achieved using a small (2 ml) flow cell housing a robust sensor that can have a flow rate of up to 1 l/min. The paramagnetic sensor measures oxygen concentrations with a response time of less than 3 seconds. 5 selectable ranges are possible on the analyser (which allows this system to be used for trace level oxygen measurements as well as oxygen purity applications): 1. 0 to 1% 2. 0 to 3% 3. 0 to 10% 4. 0 to 30% 5. and 0 to 100%
