The new Rosemount Analytical Mode RB Sensor is designed for optimum sensor life in demanding scrubber applications. pH sensors are said to be most vulnerable to failure due to poisoning of the reference junction. The new RB sensor features a proprietary multi-junction that hinders reference poisoning. This design is particularly successful against the aggressive sulfides found in scrubbers, says the manufacturer. Also, the sensor is built of chemically resistant Kynar, adding to its long life. The sensor can be installed inline, submerged or inserted via a ball valve. — Emerson Process Management, Baar, Switzerland
