General Description

Now you’ll always know HVAC performance with ProTAACS’s LTS X-SERIES Duct Temperature Sensors. These devices accurately measure ductwork temps while maintaining a sealed environment. If temps spike or fall beyond your preset limits, the sensors alert you (or on-site maintenance techs) via email, text, or call.


  • Wireless range of 1,200+ feet through 12+ walls *
  • Frequency-Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Improved power management for longer battery life **
  • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • All LTS X-SERIES sensors now have up to 3200 readings:
    • 10-minute heartbeats = 22 days
    • 2-hour heartbeats = 266 days
  • Over-the-air updates (future proof)
  • Free iProTAACS basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email

Example Applications

  • Air Duct Temperature Monitoring
  • Environmental Temperature Monitoring
  • Smart Machines & Smart Structures
  • Coolers & Freezers Temperature Monitoring
  • Datacenter Monitoring
  • HVAC Operation & Testing
  • And Many More

Commercial Grade Sensors

ProTAACS commercial-grade sensors are designed for applications in ordinary environments (normal room temperature, humidity, and atmospheric pressure). Do not subject these sensors to the following, as these environmental aggressors could degrade the device and its performance, leading to failures and burn-out:

  • Corrosive or deoxidizing gas, e.g., chlorine gas, hydrogen sulfide gas, ammonia gas, sulfuric acid gas, andnitric oxides
  • Volatile or flammable gas
  • Dusty conditions
  • Extremely low or high pressures
  • Wet or excessively humid locations
  • Places where saltwater, oils, chemical liquids, or organic solvents are routinely present
  • Applications/locations prone to excessive or strong vibration
  • Other sites where similar hazardous conditions exist

Use these products within the ProTAACS-specified temperature range. Higher temperatures could deteriorate both the product and its functionality.
