ST-H
transducers use ultrasonic technology to measure level in chemical storage and
liquid tanks.
The narrow design of the ST-H
allows the transducer to be mounted on a 2" (50.8 mm) standpipe. When
mounted correctly, it is completely protected from the process and can even be
used in harsh, corrosive environments.
During operation, the
ultrasonic transducer emits acoustic pulses in a narrow beam perpendicular to
the transducer face. The level transceiver measures the propagation time
between pulse emission and reception of the echo to calculate the distance from
the transducer to the material. Variations in sound velocity due to changes in
temperature within the permissible range are automatically compensated by the
integral temperature sensor.
