Comet T5641 – Web Sensor with PoE, Remote CO2 Concentration with Ethernet Interface

• Measured values: Carbon Dioxide
• CO2 measurement range: 0 to 10,000 ppm
• Accuracy of CO2 measurement: +/- (110ppm +5% from reading) at 25°C and 1013hPa
• Resolution: 1 ppm
• Alarm protocols: email, SNMP Trap, Syslog

Premium Web Sensors with Ethernet connection are designed for the accurate measurement of temperature, relative humidity, CO2, and barometric pressure of air in non-aggressive environments.

The T5641 is a carbon dioxide t-line Web sensor with a remote alarm. The T5641 is supplied with a CO2 probe with a 1-meter cable. The Web Sensor is equipped with an LCD display for showing current measured values. The Web Sensor can be integrated into the control systems of different manufacturers by connecting directly to a computer network using SNMP, MODBUS TCP, SOAP, syslog. The device setup can be made by the TSensor software which can be downloaded for free from the manufacturer’s website. One advantage of Web Sensors is the configuration of settings via web interface.

Upper and lower limits can be set for the alarm, which can be indicated via email or by color LED.

The visual indication of CO2 concentration is provided by three-color LED:

• ​LED shines green – CO2 concentration 0 to 1,000 ppm
• LED shines yellow – CO2 concentration 1,001 to 1,200 ppm
• LED shines red – CO2 concentration 1,201 ppm and more

A multiple point CO2 and temperature adjustment procedures lead to excellent CO2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The measurement principle is based on the NDIR principle with dual-wavelength, which automatically compensates for the aging of the sensor. The sensor is resistant against the pollution and provides maintenance-free operation and excellent long-term stability.
