Wireless ambient sensor

AMP-WRHTC

Ambient Relative Humidity & Temperature Sensor for Panels
0–95% RH5-year battery50 m range4 mounting options

An industrial-grade wireless temperature and humidity sensor for continuous environmental monitoring in electrical and industrial installations. It reports ambient conditions every 60 seconds, so you can stop condensation, corrosion and overheating before they damage equipment.

  • Measures ambient temperature and relative humidity every 60 seconds
  • Magnetic, strap, screw or 3M adhesive mounting, installed without a shutdown
  • 50 m wireless range on multiple frequency bands for global deployment, AES-128 encrypted
  • Battery-powered, with a 5-year lifespan and 24/7 monitoring

Continuous environmental monitoring for electrical installations

The AMP-WRHTC measures ambient temperature and relative humidity at 60-second intervals and transmits the data wirelessly to the receiver for real-time monitoring and analysis. All sensor data is encrypted with symmetric AES-128 encryption.

With support for multiple frequency bands, it communicates reliably in different regions around the world. Because it's wireless, readings reach you without opening electrical panels, which improves safety and keeps installation simple.

Continuous environmental data helps you spot problems early, so you can plan maintenance before overheating or excessive humidity leads to a failure.

Flexible, non-intrusive mounting

Choose the mounting that suits each location. Installation can be done without shutting the system down, which makes it ideal for live environments.

Magnetic

Snaps onto steel panel walls and enclosures.

Strap

Wraps around cables and round conductors.

Screw

Fixed through the side brackets for permanent installs.

Adhesive

Industrial-grade 3M tape for smooth surfaces.
