Siemens ST-H sensor7ML100-0AA20 has a built-in temperature sensor, can be installed on a 2 "riser, is corrosion-resistant, and can be used in harsh environments. Ultrasonic sensors are not affected by dust, moisture, corrosion, vibration, overflow, and high temperature. They are easy to install and maintenance free. Various models are available, whether for long-distance or short distance applications, whether for liquids or slurries.

Application of Siemens Sensor ST-H Product

The compact design of ST-H allows the sensor to be installed correctly on a 2 "riser, making it fully suitable for harsh processes and corrosive environments

When operating, the surface of the ultrasonic sensor (probe) emits a certain width of sound beam pulses vertically. The liquid level monitor measures the time difference between the emitted pulse and the received reflected pulse (echo) to calculate the ultrasonic sensor

The distance between the surface and the liquid surface. Within the measurement range, the built-in temperature sensor compensates for changes in sound velocity caused by changes in air temperature.

• Main applications: chemical storage tanks, liquid storage tanks
