Yokogawa Electric Corporation announces the August 16 release of the new SENCOM platform product series for the digital measurement of pH and ORP. This will join an existing lineup of quality pH/ORP solutions that includes the FLXA21 two-wire* pH/ORP-transmitter. With the release of the SENCOM platform products, Yokogawa will bring pH and ORP measurement into the digital era.

The SENCOM platform initially consists of a SENCOM module, the FU20F pH/ORP SENCOM sensor, a SENCOM cable, and the SPS24 SENCOM PC software. The installation of a SENCOM module in an FLXA21 transmitter will give it the powerful digital signal processing capabilities required to work together with the new SENCOM sensors.

Like its predecessor, the FU20F pH/ORP SENCOM sensor is a general purpose sensor that is suitable for a wide range of applications. The FU20F can store digital data and be calibrated using the SPS24 SENCOM PC software and/or the FLXA21. With these SENCOM platform products, our customers will be able to reduce the amount of maintenance work that needs to be performed on-site, thereby improving efficiency and reducing costs.

Development Background
Liquid analyzers are used in the oil, petrochemical, iron and steel, electric power, and water supply and wastewater treatment industries to control the quality of raw materials and products, monitor reactions, and manage the wastewater treatment process. The properties of certain solutions may cause damage to or foul the sensors in these analyzers and thus adversely affect measurement accuracy, so sensor calibration is required on a regular basis. However, conditions vary and it is not always safe or convenient to perform the calibration work on-site, which usually requires a converter to store data and the use of standard calibration solutions. There is a need to move this work to a safer location and also reduce measurement downtime.

Product Features
1. Better working conditions / reduced measurement downtime
2. Quick and efficient calibration
3. Efficient data management
