NTB - Deep-Well Level Probe
Brand: KOBOLD Instruments, IncThe KOBOLD NTB deep-well level probe offers a cost-effective solution for hydrostatic level measuring in wells, reservoirs, clarification plants and other water-holding vessels.
It is easy to install and ideally suited for monitoring and protecting submersible pumps in deep water wells.
The slim, 22mm-diameter level probe is perfect for tight applications.
The immersion probe consists of a measuring cell, two-wire transmitter and a special cable with capillary tube.
The housing is stainless steel with a pressure-sensitive diaphragm protected by a stainless steel cap.
The NTB determines the level signal by comparing the difference between the pressure of the water column over the probe and atmospheric pressure that is referenced through the capillary tube.
This is converted to a 4-20 mA analog signal by the level probe’s ceramic cell and integral electronics.
