Probe Dives Deep Into Wells, Reservoirs

The KOBOLD NTB probe is designed for hydrostatic level measuring in wells, reservoirs, clarification plants, and other tanks. Compact and easy to install, the NTB is well suited for protecting submersible pumps in deep wells. The probe assembly consists of a measuring cell, a two-wire transmitter, and cable with a capillary vent tube. The housing is made of stainless steel with a pressure-sensitive diaphragm protected by a stainless-steel nose cone. The level is measured by the pressure difference between the amount of water column over the probe and atmospheric pressure, which is transferred to the probe through the capillary tube. The differential pressure is then converted to a 4 mA to 20 mA analog signal by the piezoresistive cell and integral electronics. A Model NTB datasheet is available for your perusing pleasures.
