Hamilton Bonaduz AG
With Visiferm DO, Hamilton is the first company to offer a self-contained oxygen measurement in the typical 12 mm format similar to standard process pH electrodes and classical sterilizable oxygen sensors. Combined in the sensor shaft are high-temperature-resistant optical electronics, a microprocessor, a 4 - 20 mA analog output, a digital RS 485 interface with Mod Bus-protocol, and an ECS interface. The Electro-Chemical Sensor (ECS) interface allows Visiferm DO to be connected to existing classical measurement amplifiers (i.e. Yokogawa, Emerson, Knick or Mettler) designed for sterilizable oxygen sensors such as the Hamilton Oxyferm. Use the 4 - 20 mA analog output or the digital RS 485 interface integrated into the 12 mm shaft and an external measurement amplifier is unnecessary allowing measurement signals to be fed directly into a process control system.
