ARC Sensors Provide Interface To An Analog PLC

Sept. 12, 2009

HAMILTON Company, a world leader in fluid measurement, has announced the Hamilton ARC concept, a new sensor family for process control that includes pH, dissolved oxygen and conductivity measurements.

More than simply sensors, ARC Sensors are the complete solution: innovative premium quality sensors with a robust, direct, and standard interface to the PLC. Hamilton ARC Sensors send an analytical signal directly to an analog process control system while delivering at the same time the power of digital sensor management.

Bruno Waller, Director of Sales Laboratory and Sensors at HAMILTON comments: “With ARC Sensors process downtimes are minimized. The digital connection plus the on-board processor and memory built into every ARC Sensor means they can be pre-calibrated and configured in the lab. Due to the time-saving features for sensor operation and maintenance, costs and opportunity for human errors are drastically reduced.”

Classic sensors produce weak, temperamental signals that require a separate transmitter to amplify the signal before connecting to the process control system. With ARC Sensors a technology has been developed that replaces the need for transmitters. The ARC Sensor’s built-in electronics convert the low amperage measurement signal and enables several unique sensor functions. Apart from the direct analog connectivity, ARC Sensors offer a digital connection that delivers superior data integrity, increased productivity and longer life cycles. ARC Sensors are far less prone to interruption in challenging production environments than classical sensors.

ARC Sensors are available with both standard analog (4-20mA) and digital ModBus interfaces built-in and supported directly from the sensor itself.
