BAPI WIRELESS TEMPERATURE
and HUMIDITY SENSORS

• 8 Year Battery Life
• Built In Error Detection
• 100 Foot Range, Extendable to 1,000 Feet with Repeater
• Voltage, Current or Resistive Output

The BAPI Wireless Temperature or Temp./Humidity Combination system incorporates a 418 MHz transmitter along with a Receiver and one or more Analog Output Modules to send zone temperature and humidity to the DDC controller.
The wireless transmitter has an in-building range of 100 feet, extendable to the 1,000 feet with a Repeater. The transmitter has an estimated battery life of 8 years with a transmit rate of approximately once every 10 seconds.

Wireless Receivers
Receives the RF signal from one or more transmitters or repeaters, and outputs the data to an Analog Output Module.

Analog Output Modules
Converts the data from the Receiver into a resistance, voltage or current for the DDC controller. Receives data through a four-wire bus.

Wireless Repeater
Receives the 418 MHz RF signal from one or more transmitters which have a range of 100 feet. The Repeater re-transmits the signal at 900 MHz to a distance of 1,000 feet to a 900 MHz Receiver.

Field Verifiers Kits
These kits make a site survey quick and easy with a single visit. They are available for purchase or as 30-day loaners.

Wireless Thermobuffer

The BAPI Wireless Thermobuffer wirelessly transmits the temperature of walk-in freezers or coolers to a receiver within 100 feet. The Thermobuffer slows the temperature reaction of a freezer door opening to prevent false alarms or short cycling the compressor.

Wireless Universal Input Transmitter

The Wireless Universal Input Transmitter is designed to monitor 0-5VDC, 0-10VDC or 4-20mA signals and transmit that analog value to the receiver. The Digital Input version monitors any dry contact status input and transmits that On/Off status to the receiver. The Thermistor Temperature Input version takes any 10K-2 thermistor sensor and transmits it to any BAPI receiver.

Wireless Line receives 2nd AHR Expo Innovation Award
BAPI's expanded line of Wireless Temperature and/or Humidity sensors was awarded an Honorable Mention in the 2008 AHR Expo Innnovation Awards Competition in November. BAPI's initial line of wireless room sensors received an Honorable Mention in the 2007 AHR Expo Innnovation Awards Competition. The expanded line includes duct, immersion, outside air and remote sensors. BAPI's unique system extends the battery life of the wireless transmitter to 8 years while maintaining the in-building range of 100 to 150 feet, which led to the two awards.
