Relative humidity and temperature sensor TBR22-E

surface-mountwirelessbuilt-in transmitter

Overview
The TBR22-E is a wireless environmental temperature and humidity sensor designed to monitor conditions in electrical cabinets and outdoor installations. It continuously measures and transmits data to centralized monitoring software for real-time display of temperature, humidity, warning status, trend graphs, location mapping and customizable reports. Manufacturer: VTICorp – Viet Nam.

Key uses

• Monitoring temperature and humidity in electrical cabinets, switchgear and power‑grid equipment.
• Direct installation on equipment and measurement points, including bus bars and high‑voltage lines up to 500 kV.
• Applicable in industrial sites, control centers, factories, warehouses and production workshops.

Features

• Wireless 2.4 GHz communication with up to 100 m transmission in open space.
• Available in battery and self‑induction power versions (battery version ≥2 years stated operation).
• Compact housing for cabinet or outdoor mounting; protection rating IP50 (dependent on conditions).
• High measurement accuracy: ambient temperature ±0.2℃, humidity ±2 %RH; bus bar temperature accuracy ±1℃.
• Multiple color options: Red, Yellow, Blue, Black; weight 37 g; dimensions 32.5 x 31.5 x 14.4 mm.

Software capabilities

• Real‑time warning display for heat‑generating devices and abnormal conditions.
• Instantaneous values and trend graphs for temperature, humidity and pressure at measurement points.
• Lists of abnormal temperature warnings for bus bars, cable ends and contact points to support maintenance without power interruption.
• Location mapping and coordinate retrieval.
• Customizable statistics and report export; mobile monitoring via iOS/Android applications.
