ST-H Transducer

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.

What precision and reliability mean for your applications

Your facility is a busy place - and materials and conditions inside your tanks/vessels/wells are always changing. Siemens ultrasonics selects the correct echo after every measurement, giving you stable readings while still allowing rapid response to actual changes in the material level. The result? Operations are more cost-effective. Inventory monitoring is always precise. Processes can be better controlled. And expensive spill cleanups can be avoided.
