VisiFerm DO B– Optical Dissolved Oxygen Sensor

VisiFerm DO B– Optical Dissolved Oxygen Sensor
Robust inline DO measurement for brewing applications
The VisiFerm is the first optical process sensor for the measurement
of dissolved oxygen in an all-in-one, 12mm format. Designed for
applications where CIP is carried out frequently, it holds significant
advantages compared to Clark cells– fast response time, reliable
measurement, no polarization time, and simple sensor cap
replacement are just a few features of the Hamilton VisiFerm optical
standard.
Wisdom from Within– The Hamilton Arc Philosophy
With the transmitter integrated into every sensor, and using open industry standards, VisiFerm sensors offer
fully compensated, backwards compatible measurement signals that integrate directly into new or existing process control
systems. No new expensive transmitter or optical cable is required as with other optical DO systems. The Arc
µ-transmitter located in the sensor head stores all relevant sensor data, including calibration history and diagnostic
information in the sensor itself. The Arc Lifetime Indicator measures the quality of the sensor cap after calibration and
during measurement to predict when a replacement will need to be made– before a failure– so that unscheduled
downtime is avoided.
