THS327-ET
ZigBee Temperature Sensor with Probe
ZigBee 3.0 temperature sensor with a remote probe measuring water and air from -30°C to +100°C at ±1°C — for hot water, cabinets and cold chain.
Overview
The THS327-ET is a ZigBee 3.0 temperature sensor with a remote probe. The housing mounts on a wall and the probe goes where the temperature actually is — into a pipe, a tank, or the airflow inside a cabinet. It reads -30 ℃ to +100 ℃ at ±1 ℃, which covers domestic hot water, heating loops and most enclosure monitoring without a separate instrument.
What the Probe Measures
| Measurement | Range |
|---|---|
| Water temperature (probe in a pipe, tank or immersion point) | -30 ℃ ~ +100 ℃, ±1 ℃ |
| Air temperature around the probe | Same probe, same range |
| Housing ambient | -10 ℃ ~ +55 ℃ (≤ 90% non-condensing) |
It reads both water and the air around it, so one device can cover a hot-water loop and the space it runs through.
Where It Is Used
- Hot water and heating systems — flow and return temperature, cylinder and tank monitoring
- Cabinets and enclosures — the probe goes inside, the radio stays outside the metal
- Cold chain and food storage — chilled and frozen space temperature with the probe in the airflow
- Plant rooms and risers — points that are awkward to reach with a wired sensor
Power and Wiring
It is mains powered — 100~240 Vac, under 1 W. There is no battery to replace over the life of the installation, and the 19 dB radio and internal PCB antenna give up to 100 m in open area.
