Keep a close eye on the volume of liquid in your tank with this level transmitter from Siemens. Using ultrasonic signals, it bounces pulses off the surface of the fluid and measures the time it takes to travel back to the sensor. As it has a measuring range of 12m, this unit will go a long way in reaching deep and wide corners of your container. Its tough PVDF transducer stands up to chemicals and heat, making this transmitter a solid workmate for use in harsh industrial environments. You'll find it handy when working in chemical storage facilities and wastewater treatment centres.

• Built-in over-temperature compensation for improved accuracy in demanding conditions
• PBT body delivers thermal resistance for durability
• Integrated PROFIBUS PA interface for convenient communication with control systems
• LCD for easy monitoring and troubleshooting

This transmitter comes with auto false echo suppression that's designed to shield the signal from interference if it runs into any fixed objects.
