Deep-well probe
Model: NTB
Brand: Kobold
The NTB submersible level sensor is used for monitoring dynamic water levels in groundwater observation wells in accordance with Circular 17/2021/TT-BTNMT.
Overview:
The NTB submersible level sensor operates based on the hydrostatic pressure measurement principle. With a probe diameter of 22 mm and a length of 173 mm, it is easy to install in groundwater wells, reservoirs, and similar applications.

The NTB submersible level sensor features a wide measuring range, making it well-suited for monitoring groundwater observation wells with dynamic water levels from 0 to 200 meters of water column. The sensor cable can be up to 300 meters long while still ensuring stable signal transmission without interference.

To facilitate the simultaneous configuration of multiple measuring devices, including multiple water level sensors in groundwater wells, Kobold Vietnam also provides the HARTCOMM toolkit.

The operator connects a PC to the HARTCOMM toolkit and the terminal box, which is wired to the NTB level sensors according to the standard HART wiring structure for configuration, allowing up to 15 different devices to be configured.
