The ARC concept (photo) is a new family of sensors for process control, which includes pH, dissolved oxygen and conductivity measurements. More than just sensors, the devices are complete solutions that include sensors, and direct standard interface to the process-control system. In addition to the analog analytical signal, the units also deliver the power of digital sensor management. ARC Sensors are available with both standard 4–20 mA and digital ModBus interfaces built in and supported directly from the sensor itself. — Hamilton AG, Bonaduz, Switzerland
