Red-y Smart Pressure Controller

Red-y smart pressure controllers from Voegtlin of Switzerland combine reliable thermal mass flow technology with electronic pressure control. They automatically control a predefined process pressure and at the same time measure and/or limit the flow rate. They are available in a standard economic version (flow accuracy ±1% of full scale, turndown ratio 1 : 50) or a hi-performance version (flow accuracy ±0.3% of full scale and ±0.5% of reading, turndown ratio 1 : 100) and are specified for forward or backward pressure control. All devices are calibrated with real gas, which guarantees high accuracy and reproducibility.

Features of the Red y Smart Pressure Controller include:

• High accuracy flow measurement and pressure control with wide dynamic range
• Short response time: 50ms

Combines three functions:

• pressure control
• pressure control with flow measurement/limitation
• flow control with pressure measurement
• Controllers to be specified for forward or backward pressure control
• Pressure control with external transmitters, gas mixer functions and customer specific solutions available on request
• Materials: aluminium or stainless steel
• Compact design, simple installation
• Supplied with ‘get red-y’ software on CD for gas flow measuring and controlling (view flow rate & temperature, change set points, select measured gas, graphical display of measured data, adjust control parameters, monitor operating state)
• High quality meter, produced and calibrated at Voegtlin’s operations in Switzerland
• 3 years warranty (excluding battery)

Other Applications:

• Pressure control of a pressure vessel containing a stable gas mixture for laser gas or welding
• Overpressure control of a sterile chamber. The flow rate is used as a leakage indicator.
