Hamilton Co, a global specialist in fluid measurement, has launched a new sensor family for process control that includes pH, dissolved oxygen and conductivity measurements.
ARC sensors are described as a complete solution: innovative sensors with a robust, direct, and standard interface to the PLC. The sensors send an analytical signal directly to an analogue process control system while at the same time delivering the power of digital sensor management.
Bruno Waller, director of sales, laboratory and sensors, at Hamilton said: "With ARC sensors process downtimes are minimised. 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 analogue 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, the company says.
The sensors are available with both standard analog (4-20mA) and digital ModBus interfaces built-in and supported directly from the sensor itself.
