   BAPI Wireless Duct Temperature or Temperature/Humidity Transmitters feature medical-grade closed cell foam to seal the probe insertion hole and to absorb vibration. Mounting feet allow for easy installation directly to the wall of the duct. The wireless Duct Units come with a watertight BAPI-Box enclosure to withstand high humidity and condensation and perform under real world conditions.
  The Wireless Duct unit measures the duct temperature and humidity and transmits the data through 418MHz RF to a receiver. It has an in-building range of 100 feet and an estimated battery life of 8 years using two high-capacity 3.6V lithium batteries with a transmit rate of about once every 10 seconds. Each transmitter has a unique address with built in error detection. Each variable sent by the transmitter is picked up by the receiver and converted by a BAPI Analog Output Module to a voltage, current or resistance signal which is sent to the controller. The unit can be set up to trigger an alarm on the controller when the batteries need replacing.

*Actual distances will vary depending upon building construction and other factors.
