TX Carbon Dioxide Industrial Sensors with Transmitter

The TX Carbon Dioxide (CO2) Industrial Sensors are designed for industrial applications where RS485 Modbus RTU or 4-20mA outputs and 6-24VDC is required.  The TX Sensor Smart Boards combine the GSS ExplorIR®-M 5%, 20% or 100% carbon dioxide sensors with a PCB that provides RS485 or 4-20mA output options and 6-24VDC power options on a 30mm PCB for industrial applications. Features Low Drift & Cross-Sensitivity Communicates directly to a PLC Easy Calibration, Easy Integration, Compact Wide Range of Power Options RS485 Modbus RTU and 4-20mA analog outputs Sensor Life Expectancy: > 15 years Models TX-24: CO2 5% Sensor with TX Board TX-241: CO2 5% Sensor Development Kit TX-26: CO2 20% Sensor with TX Board TX-261: CO2 20% Sensor Development Kit TX-25: CO2 100% Sensor with TX Board TX-251: CO2 100% Sensor Development Kit Specifications Measuring Gas: Carbon Dioxide Measurement Range: 0-5%, 0-20% or 0-100% CO2 Sensing Method: NDIR Measurement Interval: 1 Sample/second Response Time: < 60 seconds Warm-Up Time: < 60 Seconds at 72°F (22°C) Temperature Accuracy: +/- 2 degrees C Power requirements: 6-24VDC Outputs: RS485 Modbus RTU, 4-20mA analog Operating Temperature: -30°C to +60°C Barometric Pressure Range: 500 to 1200 mbar Sensor Life Expectancy: > 15 years Warranty 90 days - See CO2Meter Inc., Terms and Conditions. Documents  Manual (pdf)  RS485 Modbus RTU Interface (pdf) Software Free Easy-to-use GasLab® Software The Devkit uses GasLab® software for setup, calibration, data logging, and real-time data analysis via USB. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products. System Requirements Windows XP SP2 or newer Microsoft .Net 3.5 Runtime Libraries Accessories Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently. TC-1 - 3 mm side mounted ports TC-2 - 3 mm top mounted ports TC-3 - 4.5 mm top mounted ports Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system. Nafion tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur. Micro gas sampling pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
