PrimIR: High-resolution CO2 sensor module with short response time
2016-11-28 08:57:18, Angst+Pfister Sensors and Power AG Pewatron has a new CO2 sensor module with a short response time on offer that is particularly well suited for medical applications and food control. Capnometry is an example of a medical application (monitoring CO2 levels in exhaled air) where the response time of the sensor is important to make qualitative and quantitative statements about the condition of the person being monitored. In food monitoring, sample volume plays a role when modified atmosphere packaging is to be tested that contains only small volumes of gas. In addition, there are quantitative advantages if only a small amount of gas has to be sampled for the gas analysis, as this means that more packages of a batch can be tested at the same time.
The PrimIR CO2 module is configured for a measuring range of 0 to 5 % O2 or 0 to 20 % CO2. Output is via a simple UART interface that can be easily read using serial transmission protocols such as RS-485.
The PrimIR sensor has been calibrated for forced flow and has connections for tubing systems. The flow-optimized design enables fast measurements regardless of flow rate, even with small total volumes. Gas volumes of only 2 ml or less are required for accurate measurement. The response time of the sensor (T90) is less than 0.5 seconds at flow rates of 500 ml/min and more.
