CMT CO transmitter

CMT CO transmitter

Product catalog summary

Applications
CMT devices are used in environments with potential CO gas emissions, including commercial parking garages, apartment garages, tunnels, terminals, car and bus maintenance garages, warehouses, factories, and auto service centers.

Product Description
The CMT is a carbon monoxide transmitter designed for easy use and reliability in detecting CO gas. It is primarily used to control ventilation in areas where high CO concentrations pose health risks.

Specifications

Performance: Measurement range is 0 to 300 ppm CO with a linearity of ≤2% on 300 ppm CO, cross sensitivity of ≤2% on 300 ppm CO, and reproducibility of ≤3 ppm.
Technical Specifications: Response time is less than 60 seconds, gas entry by diffusion, and uses an electro-chemical measuring element. Operating temperature ranges from -10 to 40 °C with humidity between 15 to 95% rH.
Physical: The case dimensions are 90 x 95 x 36 mm, weighing 87 g, made of ABS with a PC lid, and has an IP54 protection standard.
Electrical: Requires a supply voltage of 14 to 28 VDC, with an output signal of 4 to 20 mA and a maximum load of 300 Ω.

Conformance
The device is TÜV-approved according to VDI 2053, complies with R.F.I standards EN 50 081-1 and EN 50 082-2 B, and meets CE marking requirements under the EMC Directive 2014/30/EU, RoHS Directive 2011/96/EU, and WEEE Directive 2012/19/EU.

Certifications
The company is certified by DNV GL for ISO 9001 and ISO 14001 standards.
