Function and system design
Measuring principle The symmetrical vibrating fork is excited to its resonant frequency. Vibration characteristics change when the
fork is submerged in solid material. The change is registered by the electronics which actuate an electronic
switch or relay.
The tip of the Soliphant fork is particularly sensitive, while the base of the fork is completely insensitive.
This enables solids of very low density to be detected even with material build-up on the vessel walls.
Soliphant FTM260 can be operated in both minimum or maximum fail-safe mode, i.e. the electronic switch
opens or the relay de-energises on reaching the limit value, on a fault or on a loss of power.
Measuring system
The function of the electronic switch or relay
and the LED is dependent on both the level and
fail-safe mode selected

Note!
Always connect in series with the load!
Check the following:
• the residual current in blocked state (up to 3.8 mA)
• that for low voltage
– the voltage drop across the load such so that the minimum terminal voltage at the electronic insert (19 V)
when blocked is not too low.
– the voltage drop across the electronic insert when open is observed (up to 12 V).
• that a relay cannot de-energise with a retaining current below 3.8 mA.
If this is the case, a resistor should be connected parallel to the relay.
