New Definition of Connectivity: Hamilton Arc™ Hx Sensors

Hamilton sets new standards in connectivity matters with the Arc™ Hx series of sensors. Thanks to an interference-free and spatially flexible data transmission between the sensor and process control system, the industrial suitability of sensors is optimized.
Specific features of the new series are transmitter-free communication, integration of the HART(Highway Addressable Remote Transducer) data transfer protocol and mobile sensor monitoring via handheld, smart phone or tablet PC.
As with all sensors of the Arc series, an external transmitter is not used in Arc Hx sensors.
Since its tasks are taken over by a microprocessor integrated into the sensor head, the sensor and process control system can directly communicate with one another.
As a result of that, the typical data transmission errors that occur near external transmitters are a thing of the past.
By using novel components in the building of the microprocessor, any heat development in the sensor head was additionally eliminated in the Arc Hx sensor, making these sensors suitable for explosion-prone areas.
All sensors of the Arc Hx series are capable of communicating with the process control system via HART, which is by far the most commonly used data transfer protocol in the process industry.
By adopting this communication standard, Arc Hx series sensors can be easily integrated into existing installations.
If several sensors are being used and the process surroundings require mobility, the user can monitor the Arc Hx sensors from afar with the Arc View Handheld mobile.
It is capable of the simultaneous numerical and graphical read-out of the measured values in up to 31 sensors and of controlling measuring quality and functionality.
Last but not least, the sensors can also be calibrated via the Arc View Handheld.
Alternatively to the handheld, Arc Hx sensors can also be monitored via smart phone or tablet computer. All series sensors are equipped with a Bluetooth® 4.0 interface and can therefore communicate directly with an iPhone® or iPad®.
Hamilton makes the app needed for this available with the “HDM Mobile” application tool, which can be downloaded free of charge in the iTunes® app store.
Moreover, with the Arc online service, the values measured by the sensors can be retrieved from any Internet access.
Hamilton presented the first sensor of the new series, the VisiFerm DO Arc Hx, at the Achema 2012.
It is the first sensor with ATEX approval for optically measuring the partial pressure of dissolved oxygen. Sensors for measuring the pH and conductivity parameters will follow soon.
