Mettler Toledo InPro 5500i inline CO₂ sensor

Mettler Toledo Process Analytics has launched the InPro 5500i for inline CO₂ measurements for beverage production applications. Using thermal conductivity technology, the sensor provides highly accurate and stable CO₂ measurements. Immunity to background gases such as oxygen and nitrogen means CO₂ measurement is highly selective. Measurements are also comparable to well-known references methods.

The device can be installed easily with a choice of process connections including Varivent, Tri-Clamp and 28 mm or M42. Its hygienic and simple membrane design reduces maintenance efforts, while the absence of moving parts ensures a reduced failure rate and high operational uptime.

Mettler Toledo’s Intelligent Sensor Management technology is installed on the InPro 5500i: advanced diagnostics tools, plug-and-measure feature and precalibration routine support troublefree and fast start-up and operation. The membrane integrity detection function informs operators of a drop in membrane reliability. This feature allows operators to perform a membrane change before measurements and product quality are affected. The dynamic lifetime indicator and adaptive calibration timer inform operators when the sensor will need servicing. Maintenance shifts from a regularly scheduled or reactive process to one where tasks can be planned in advance. Calibration of the device is a simple operation and can be conveniently performed inline.

The device protects itself from damage during SIP/CIP cycles or when the purge gas or sensor membrane fails, and therefore helps provide long sensor lifetime.
