The Model SDT Submersible Hydrostatic Level Transducer indicates the level of liquid by continuously measuring hydrostatic pressure via its isolated sensing element. Once the sensor measures the pressure, the data is transmitted by a 4 to 20 mA, 0.5 to 4.5 VDC, 1 to 5 VDC, 1 to 6 VDC, or 0 to 5 VDC output signal. This unit can be customized for OEM applications.
This design provides for excellent linearity and repeatability, low hysteresis and long term stability. The Model SDT sensor is easy to install; simply lower the transducer into a vessel or well. It’s that easy. All the electronics are mounted in a submersible 316 stainless steel housing.
A special cable support bracket is also available. This gives extra stability to the transducer when used with longer lengths of cable (up to 2500 feet) or when used in an agitated liquid. A conduit adapter is also available.
The transducer is available calibrated for any span needed, from 0 to 1 psi or 0 to 0.07 bar (0 to 2.31 feet or 0 to 0.7 meters of water) to 0 to 300 psi or 0 to 20 bar (0 to 690 feet or 0 to 211 meters of water).
