Dissolved Oxygen Optical Sensors

The first self-contained oxygen measurement in the popular 12 mm format similar to standard process and pH electrodes and classical sterilizable oxygen sensors. VisiFerm DO optical sensors demonstrate a number of substantial advantages because of a symbiosis of sensor and measurement amplifier- an intelligent sensor. Available in standard and Arc versions.

VISIFERM™ DO offers the widelyused Modbus RTU interface, enabling  up to 32 sensors or other devices to be  wired onto the same bus, in a highly cost-effective installation. The Modbus

interface offers users comprehensive information, including input from the sensor’s diagnostics and health indicator. Numerous gateways are available to interface Modbus to Foundation Fieldbus, Profibus, and others.

Features & Benefits:
Application:

• No fragilemembrane –with a solid Sensor Cap
• Instantlystable values, lowdrift, quick response
• Flow-independent
• Electrolyte-free,so no leakage
• No H2S or CO2 effect

Maintenance:

• Just one single,simple,replaceable spare part – the robust Sensor Cap
• Convenientcalibration in the laboratory, because calibration data is stored in the sensor
• Precalibrated,ready-to-use sensorsfromstockminimize service time and costs

Installation:

• Backwards compatible with classical oxygen sensors, operates with traditional transmitters and SOPs, or -
• Can be connected directly to a PLC or PCS using a 4 to 20mA or Modbus RTU interface 

VisiFerm DO
Hamilton is the first company to offer a self-contained oxygen measurement in the popular 12 mm format similar to standard process and pH electrodes and classical sterilizable oxygen sensors. VisiFerm DO optical sensors demonstrate a number of substantial advantages because of a symbiosis of sensor and measurement amplifier- an intelligent sensor.

VisiFerm DO Arc
The VisiFerm is the first optical sensor ever for the measurement of dissolved oxygen that has significant advantages compared to classical Clark cells because there's no electrolyte needed and the luminophore is embedded in a robust sensor cap. Typical applications are biotechnology, water treatment and monitoring as well as in breweries, wineries and soft drink processing. Available with the innovative Arc technology.

VisiFerm DO B
The VisiFerm DO B is designed to measure dissolved oxygen (DO) in brewing applications, notably during fermentation, filtration, and filling. It has all the advantages of Hamilton’s VisiFerm optical DO sensors, including reliable measurement down to ppb levels, fast response time, and easy maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarization time, and simplified maintenance. In addition, the CIP (Cleaning In Place) and brewery modes enable reliable measurements in environments, such as breweries, which may not allow for calibration after every CIP.
