Optical oxygen measurement
Combined in the VISIFERM™ sensor shaft are: high-temperature resistant optical electronics, microprocessor, 4 to 20 mA analog output, digital RS 485 interface with ModBus protocol, and ECS interface. The Electro-Chemical Sensor (ECS) interface allows VISIFERM™ DO to be connected to existing classical measurement amplifiers designed for sterilizable oxygen sensors, such as the HAMILTON OXYFERM™. Use of the 4 to 20 mA analog output or the digital RS 485 interface (both integrated into the 12 mm shaft) makes an external measurement amplifier unnecessary, allowing measurement signals to be fed directly into a process control system.

HAMILTON has successfully
manufactured steam-sterilizable, autoclavable, CIP-compatible sensors
for pH, oxidation/reduction, conductivity, and oxygen measurement
VISIFERM™ DO sensors have been evaluated
VISIFERM™ DO sensors are developed to be steam sterilized and autoclaved without difficulty. CIP cleaning is also tolerated very well. These properties, along with the standard design form of a classical 12 mm sensor with PG 13.5 thread, make VISIFERM™ DO superior for use in fermenters and similar demanding applications.
VISIFERM™ DO is already being used to monitor carbon dioxide recovery, and is finding further application in the wort tank. Installations in the area of beer and beverage bottle filling are still in various test runs.
