General

The Waterpilot FMX21 transmitter with capacitive, oil-free ceramic measuring cell is typically used in the process and environmental applications for hydrostatic level measurement. With HART output, the measuring ranges can be freely adjusted and a density-compensated level measurement can be activated. It is certified for drinking water and offers integrated temperature measurement. Versions for applications in wastewaters and sludges or usage in salt water are also available.

Features

• Robust overload-resistant high purity ceramic sensor (99.9% Al2O3)
• Flexible scaling of 4 to 20mA with superimposed HART 6.0 output
• Highest level accuracy using temperature compensated density correction
• Simultaneous measurement of level and temperature with optionally integrated Pt100 temperature sensor
• Extensive range of accessories provides complete measuring point solutions
• Climate proofed sensor thanks to completely potted electronics and 2-filter pressure compensation system
• Small outer diameter of 22mm (0.87") version suitable for drinking water applications and for use in bore holes and wells with small diameters
