The Model SDT Transmitter indicates the level
of liquid by continuously measuring hydrostatic
pressure via its sensing element, an ion implanted
silicon semiconductor chip with integral
Wheatstone Bridge circuit. Once the sensor
measures the pressure, the data is transmitted by
a 4 to 20 mA output signal. This design provides
for excellent linearity and repeatability, low
hysteresis and long term stability.
The Model SDT is simple to install, too. Simply
lower the transmitter into a vessel or well. It’s
that easy. All the electronics are mounted in a
submersible 316 stainless steel housing.
The transmitter 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).
To complete your liquid level measurement and
control system, use the AMETEK Drexelbrook
Model CDM Controller with Digital Meter
in addition to the Model SDT Submersible
Transmitter.
