Field of application
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.
Three different versions for drinking water, wastewater and sewage, saltwater.
Process connections: Suspension clamp, cable gland
Temperature: –10 to +70°C (14 to 158°F)
Measuring range: 0 to 20bar / 200m H20 (0 to 300psi / 600ft H2O)
Accuracy: ±0.2%, "Platinum" ±0.1%
International explosion protection certificates, marine approvals, drinking water approval
Benefits
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
