GMW83RP HVAC Temperature, Humidity and CO2 Sensor for DCV, Wall Model, Voltage outputs.

The Vaisala GMW80 series CARBOCAP® carbon dioxide and temperature transmitters are wall-mount transmitters designed to fulfill the needs for CO2 measurements in standard demand controlled ventilation (DCV) and Indoor air quality monitoring (IAQ). The CO2 measurement is based on a second generation CARBOCAP® sensor, which uses a novel, silicon-based microchip emitter.

The internal reference in the CO2 sensor guarantees the best stability and operation also in constantly occupied buildings without frequent readjustments.

The CARBOCAP® sensors give correct CO2 measurements immediately when powered on. Proper operation can be verified immediately after snapping on the device cover.

The GMW83RP uses the interchangeable Vaisala INTERCAP® humidity sensor which requires no recalibration when the sensor is replaced. The sensor is also insensitive to dust as well as to most chemicals.

The GMW83RP also includes a Pt1000 RTD Class F 0.15 IEC 60751 (Class A) that can be wired to a controller for temperature measurement

There is an optional traceable calibration certificate that includes 2 points for CO2 (1000 ppm and 2000 ppm), one Relative Humidity point (apr.30%RH) and one Temperature point (apr 23°C).

The package includes:

  • GMW83RP transmitter
