Dwyer Instruments CMT-DN | Duct mount carbon monoxide transmitter | With 4-20 mA and 2-10 VDC outputs
A carbon monoxide transmitter that reliably detects and transmits low carbon monoxide concentrations inside a loading dock or parking garage is the Series CMT, CMT-DN. It is possible to order transmitters in duct mount or wall mount variants. Field-selectable universal current and voltage outputs are compatible with the majority of popular building management controllers. For wall mount variants, there are optional relays and an alert buzzer that can be used to connect straight to an exhaust fan or warning light. Internal potentiometers can be used to field calibrate the Series CMT. Password protection is applied to software settings, including set points for optional relay outputs.
