Online Process Meters

California-based Sensorex, producer of electrochemical and optical sensors, and instrumentation for realtime water analysis, has expanded its family of water quality and online process transmitters, adding four new models to provide basic monitoring and control. The TX10 pH/ORP and CX10 Conductivity and transmitters offer simple monitoring, while the TX20 pH/ORP and CX20 Conductivity controllers can also be programmed for process control. These small-footprint panel-mount transmitters provide reliable data and control of process fluids, in a cost-effective package. Applications include water quality, chemical, electronics, food production, environmental and wastewater treatment.

The TX10 measures pH or ORP and temperature. The CX10 transmitter measures conductivity, resistivity, and temperature. Both provide convenient local display of values and easy access to calibrate online process sensors. The primary measurement 4-20mA signal output can be integrated into a range of process control systems.

The TX20 monitors pH or ORP, with temperature compensation for accurate measurement and control. The CX20 monitors conductivity or resistivity, also with temperature compensation. Both the models provide local display of values with relay output for alarm or control of process conditions ideal for use with chemical feed systems.

All four models are simple to operate, with push button interface and clear LCD displays. They are designed to save panel space with a small footprint 1/8 DIN enclosure. The devices are 100-240 VAC line-powered.
