The Series WTP Wireless Temperature Sensors can be quickly
installed on chilled water lines, air ducts or outside a building without
having to run additional wiring. By sampling the temperature
measurement every 10 seconds, the 3.6 V lithium battery is able to
power the unit for up to 8 years.
A reliable 418 MHz signal can carry the measurements up to 100 feet
without a repeater. With the optional 900 MHz repeater, measurements
can be transmitted up to 1000 feet away.
