Schneider Electric has announced the expansion of its Smart pH product family. Now the enhanced Model 876PH-S transmitter, along with recently released models PH10 and PH12 Smart pH Sensors, provides Smart pH measurement solutions across a wider array of industries and applications.
The 876PH-S transmitter now has a backlit LCD display and enhanced diagnostics with predictive maintenance capabilities. The local user interface can be operated in seven languages: English, French, Spanish, Portuguese, Italian, German, or Russian. With HART digital communications, the FDT-certified DTM can be operated in Chinese and Japanese in addition to the seven other languages.
Connected to either PH10 or PH12 Smart pH sensors, the transmitter can access vital data in the sensors’ non-volatile memory, such as calibration coefficients, “date of birth”, firmware revision, model code selection, sales order number, serial number, time in service, and the sensor history log. The sensor history log is a rich source of data from which the transmitter can deduce the health of the sensor by analyzing response time and calibration coefficients such as “slope” as they have evolved over time. The 876PH-S can predict when a sensor’s slope value is expected to reach a low limit specified by the user and allows maintenance to be scheduled in advance and not performed unless necessary.
