Comet T5145 – CO2 Concentration Transmitter with 4-20mA Output, Duct Mount

• Duct mount CO2 concentration transmitter with 4-20 mA output
• CO2 measuring range: 0 to 2000 ppm
• Accuracy: +/-(50ppm +2% from reading) at 25°C and 1013hPa
• Resolution: 1 ppm

The T5145 is a CO2 concentration transmitter with 4-20 mA output. Measured CO2 concentration values are converted to 4-20mA current output. Transmitter contains a microprocessor-based control circuitry in a durable plastic case with connection terminals. The device can be duct-mounted. Measured values are displayed on a dual line LCD display.

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

• LED shines green – CO2 concentration 0 to 1000 ppm
• LED shines yellow – CO2 concentration 1001 to 1200 ppm
• LED shines red – CO2 concentration 1201 ppm and more

The multipoint calibration of the CO2 sensor leads to excellent accurate measurements of CO2 in the entire operating temperature range. With this sensor the device is able to meet the demanding requirements for outdoor use. 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.

Applications for this device include:

• Production facilities
• Healthcare and lab storage
• Food industry
• Building management
