The Series WTP-R Wireless Remote Probe Temperature Sensors
can be used to monitor surface temperature of water lines or in locations
where space is limited. For greater flexibility, the enclosure for the
electronics can be mounted up to 25´ from the temperature
measurement point. By sampling the temperature measurement every
10 seconds, the 3.6V 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.
MOUNTING
Mount unit to surface using four #10 screws through the holes in the
mounting feet. For concrete or cinder block, pre-drill four 5/32˝ (4 mm)
holes to 1-3/4˝ (45 mm) depth. On duct models, only compress gasket
half of original thickness.
