SIEMENS ST-H Transducer Ultrasonic level measurement
New & Original with very competitive price and One year Warranty
T-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.
Benefits
Can be mounted on a narrow standpipe
Immune to corrosive and harsh environments
Integral temperature sensor
