With the new 9950-10/11 transmitter (photo), this company has added a six-channel option to its 9950 product family. Additional features, such as derived functions and Boolean logic, provide expanded control options that may reduce the need for programmable logic controllers (PLCs) on small skids and systems. The intuitive menu makes the transmitter easy to operate, and relay activations are clearly signaled by the user-selectable red backlight display. Additional versatility is provided with its capability for multiple parameters through support of flow and analytical sensors. The 9950 features up to six 4–20-mA outputs, Modbus connectivity and input and outputs that are fully customizable. The line also offers a choice of sensor combinations. The 9950 is suitable for a wide variety of applications, including water- and wastewater-treatment systems, reverse osmosis, deionization, media filtration, chemical manufacturing, air scrubbers, cooling towers, aquaculture and more. — GF Piping Systems, Irvine, Calif.
