Series WTP Wireless Temperature Sensor

Transmits up to 100 Feet, NEMA 4X Enclosure

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.
