Soliphant T FTM20, FTM21
4 Endress+Hauser
Cable specifications
Use a shielded cable in the event of strong electromagnetic radiation.
Temperature resistance The connecting cables must withstand an ambient temperature of +20 K.
Cable entries M20x1.5 (cable gland); NPT ½; G ½
Input
Measured variable Level (according to the mounting location and the overall length)
Measuring range
(application)
The measuring range depends on the mounting location of Soliphant T and the length of the pipe extension
selected. The pipe extension is available in the following lengths: 500 mm, 1000 mm, 1500 mm (20 in, 40 in,
60 in).
Input signal Probes covered => small amplitude
Probe not covered => large amplitude
Measuring frequency 700...800 Hz
Output
Galvanic isolation FEM22:
Between sensor and power supply
FEM24:
Between sensor, power supply and load
Switch behaviour Binary
Power-on behaviour When switching on the power supply the output is set to "signal on alarm".
After a maximum of 3 s it switches to the correct output signal.
Fail-safe mode Minimum/maximum quiescent current safety can be switched at electronic insert
MAX = maximum safety:
When the vibrating rod is covered, the output switches in the direction of the signal on alarm
Used for overfill protection for example
MIN = minimum safety:
When the vibrating rod becomes exposed, the output switches in the direction of the signal on alarm
Used for empty running protection for example
Switching delay 0.5 s when the sensor is covered
1 s when the sensor is exposed
Ex specifications FEM22, FEM24:
– Explosion protection for explosive dust-air mixtures:
Dust-Ex, DIP
