New Sensors for Measurement of Dissolved Oxygen and Lowest Conductivity

With four new electrochemical sensors Hamilton is expanding the possibilities and application areas of the ARC system. ARC is a newly developed technology for process analysis launched in 2010 by Hamilton Bonaduz AG, Switzerland. The system works with intelligent sensors containing the integrated functions of a transmitter. Now Hamilton has expanded its sensor portfolio with four more electrochemical ARC sensors for use in biotechnology and pharma processes, the measurement of oxygen traces and measurement with high CO2 partial pressure as well as sensors for monitoring pure water conductivity.

The OXYFERM FDA ARC sensor is designed for electrochemical oxygen measurements in fermentations and pharma processes, the OXYGOLD G ARC sensor for measurements of low-ppb oxygen traces in aqueous media. OXYGOLD B

ARC sensor measures low-ppb oxygen traces in beverages containing CO2. For monitoring of pure water quality in industrial processes, the new CONDCELL PWSE ARC with Triclamp adapter has now been released by Hamilton. It offers a dynamic measurement range from 0.01 to 2000 μS/cm covering processes in pharmaceutical water generation and power plants.

All Hamilton ARC sensors offer fully compensated intelligent measurement signals with two 4-20mA analogue outputs, digital Modbus interface and wireless transmission using the optional ARC Wi adapter. All new sensors are fully compatible with the existing ARC product family: VISIFERM DO ARC, ARC pH, CONDUCELL ARC, ARC View and ARC Wi. Users benefit from various advantages of the new technology of the ARC sensors compared
to conventional systems in process analysis that work with transmitters. Procurement costs are saved since the ARC sensors already contain the transmitter functions.

The installation work is reduced leading to further cost savings, too. For operations the much easier and more convenient handling during process analysis provides for higher staff productivity. In addition the ARC equipment needs less space. Due to the direct connection to the PC/PLC the system delivers a reliable, robust signal.

None of the usual interferences from humidity, cable length or other factors occur. The ARC sensors already contain intelligent functions such as diagnostic, history and calibration data.
