TSENSE is an advanced and versatile 3 in 1 transmitter. Designed for installation in the air conditioned zone, it measures CO2 concentration, temperature, and humidity in the ambient air. The data is transmitted to a Building Automation System or stand-alone controller using a standard output (analog or relay) or via BACnet(TM) or Modbus communication protocols. TSENSE combines all necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools and other facilities, allowing for a comfortable and healthy environment for the occupants. It is flexible in design and is suitable for use in many different energy efficient ventilation strategies. The TSENSE incorporates a NDIR (non-dispersive infrared) technology and complies with ASHRAE 189.1. (TSENSE units can be configured in the field using the touch screen display or buy UIP5 Software via a USB to Serial adapter cable with a 3.5 mm audio jack). The TSENSE Series is covered by ACI's Five (5) Year Limited Warranty.
