Function and system design
Measuring principle A piezoelectric drive excites the vibrating rod of Soliphant T FTM20, FTM21 to its resonance frequency.
If medium covers the vibrating rod, the rod's vibrating amplitude changes (the vibration is damped).
Soliphant's electronics compare the actual amplitude with a target value and indicates whether the vibrating
rod is vibrating freely or whether it is covered by medium.
L00-FTM2xxxx-15-06-xx-xx-001
A = amplitude
Measuring system Soliphant T is a compact electronic switch.
Thus, the entire measuring system only consists of:
• Soliphant T FTM20 or FTM21 with FEM22 or FEM24 electronic insert
• a supply point and
• the connected control systems, switching units, signalling systems (e.g. lamps, horns, PCS, PLC, etc.)

Measuring range (application)
Input signal Probes covered => small amplitude
Measuring frequency 700...800 Hz
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).
Probe not covered => large amplitude
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

Pressure instruments with permitted pressure ≤ 200 bar (2 900 psi) Pressure instruments with a
flange and threaded boss that do not have a pressure-bearing housing do not fall within the scope of
the Pressure Equipment Directive, irrespective of the maximum permitted pressure.
Reason:
According to Article 2, point 5 of EU Directive 2014/68/EU, pressure accessories are defined as
"devices with an operational function and having pressure-bearing housings".
If a pressure instrument does not have a pressure-bearing housing (no identifiable pressure chamber
of its own), there is no pressure accessory present within the meaning of the Directive.
Note:
A separate analysis must be performed for pressure instruments that are part of safety equipment
designed to protect a pipe or vessel from exceeding allowable limits (safety accessory in accordance
with Pressure Equipment Directive 2014/68/EU, Article 2, point 4).
RCM-tick mark The product or measuring system supplied complies with the regulations of the Australian
Communications and Media Authority (ACMA) for network integrity, performance characteristics and
health and safety requirements. The specifications for electromagnetic compatibility, in particular, are
observed. The products bear the RCM-tick mark on their nameplate.
EAC conformity The measuring system meets the legal requirements of the applicable EAC Directives.
These are listed in the corresponding EAC Declaration of Conformity along with the standards applied.
A0029561
Endress+Hauser confirms successful testing of the device by affixing to it the EAC mark.
RoHS The measuring system complies with the substance restrictions of the EU Directive on the restriction
of the use of certain hazardous substances 2011/65/EU (RoHS 2).
