High-Concentration CO2 Transmitter – Overview

The High-Concentration CO2 Transmitter is a non-dispersive infra-red (NDIR) CO2 sensor module designed specifically for incubator applications.  The GS45 comes with internal and external mounting options and with pigtail wire connections. The sensor module is powered with DC 12 V and converts the measurement into a linear voltage signal (0 … 5 V corresponding to 0 … 20 vol.% CO2) or RS-485 (Modbus communication corresponding to 0 … 30 vol.% CO2 ). The GS45 also comes with simple maintenance features. The BC wiring connection allows the user to perform a quick background calibration (BC).

Note 1: In normal IAQ applications. Accuracy is defined after minimum 3 weeks of continuous operation. However, some industrial applications do require maintenance.
Please, contact us for further information.
Note 2: SO2-enriched environments are excluded.
Note 3: Notice that absolute maximum rating is 14 V, so that sensor can be used with 12 V±10% supply.
Note 4: Different options exist and can be customized depending on the application. Please, find possible options in this document and contact us for further information.
Note 5: Accuracy is specified over operating temperature range. Specification is referenced to certified calibration mixtures.
Uncertainty of calibration gas mixtures(±2% currently)is to be added to the specified accuracy for absolute measurements.
