TYCO/GOYEN        OPAL 200 Series

Opacity and Dust Monitoring Systems

The 200 series dual channel opacity and dust monitoring systems are designed, tested and certified to the USEPA Performance Specification #1 (opacity) and are also compliant for use in USEPA PS-11 (quantitative dust) monitoring applications. They can be supplied as either standard application systems or EXp certified systems for use in hazardous areas. 200 Series system outputs and control features are extremely versatile and offer many unique features not available in competitor systems. This allows the OPAL 200 to be the ideal replacement system in the event of urgent site breakdowns.

DO Sensors

Optical Oxygen Measurement with Built-in Electronics in a 12mm Format

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.
