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.
Why Choose the VisiFerm DO?
Application:
 No fragile membrane– One
optical cap to replace
 No polarization time– Fast,
stable values
 No drift, fast response time
 Independent of changes in
flow
 Not affected in the presence
of CO2
Maintenance:
 No internal electrolyte– One
Installation
 Backwards compatible– can
single, simple, sensor cap
operate with existing
replacement
transmitters by generating a
 All relevant sensor and
calibration data stored in the
sensor head
 Pre-calibrate so that ready to
use sensors can be stored in
stock
nA signal
 Can be connected directly to
a process control system
using a 4-20 mA or digital
interface

Global Optical Sensor Market Optical sensor converts the light into electric signals. It measures physical quantity of light and converts light into form which can be interpreted by instrument. Optical sensor is connected to electrical trigger which can reacts as per change in signal. Optical sensor has ability to measure change in wavelength of light. Optical sensor works with either single point method or through distribution point method. In single point method single phase change is required to activate the sensor. In distribution point method, the sensor is reactive along a series of sensors.
