DocumentDocumenttSENSE (Disp) CO2, Temperature and RH Sensor with colour touch display tSENSE is an advanced and versatile 3-in-1 sensor designed for installation in the air-conditioned zone. It measures CO2 concentration, temperature and humidity in the ambient air accurately without need for additional compensation true read. The data transmits to a BMS system or stand-alone controller using industry standard output signals and communication protocols. tSENSE combines all the necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools and other facilities. Using CO2monitoring for demand control ventilation (DCV) allows healthy, comfortable and cost-effective environment for the occupants. tSENSE is flexible in design with temperature control in combination with humidity control optional. Though suitable for use in many different energyefficient ventilation strategies, Senseair welcomes any discussions for specific needs. Complies with ASHRAE standard 189.1 (±50ppm @ 1000ppm of measured CO2 value) Standard specification Measured gas Operating principle Measurement range OUT1 CO2 OUT2 Temperature OUT3 Relative Humidity Relay CO2 Accuracy (CO2) Dimensions [mm] Dimensions display [mm] Life expectancy Operation temperature range Power supply Communication Carbon dioxide (CO2) Non-dispersive infrared (NDIR) 02000ppm 010VDC, 02000ppm 010VDC, 050°C 010VDC, 0100%RH On 1000 ppmvol Off 900ppmvol ±30 ppm ±3% of reading 125 x 85 x 22 49 x 37 >15 years 050°C 12VDC, 24VAC/DC Modbus (MB) or BACnet (BAC) protocol over RS485 Key benefits · Maintenance free · Three sensors in one housing: CO2, temp and RH · Colour touch display with possibility of customisable GUI · PIN codes for access to display and meter settings · Improved housing design for effective measurement Document: PSH0109 Rev: 18 ©2019 Senseair AB.

In normal IAQ applications, accuracy is defined after minimum three (3) ABC-pe riods of continuous operation with ABC. Accuracy is specified over operating temperature range. Specification is refer enced to certified calibration mixtures. Uncertainty of calibration gas mixtures (±1% currently) is to be added to the specified accuracy for absolute measurements. Repeatability is included. Uncertainty of calibration gases (±1%) is added to the specified accuracy. Depending on display brightness setting. Can be configured with PC software UIP (version 5 or later). See information at senseair.com Document: PSH0109 Rev: 18 ©2019 Senseair AB. All rights reserved. Page 2/2 An Asahi Kasei Group Company.
