Mounting

If a malfunction is detected or in case of power
failure, the electronics takes on a dened switching
condition, i.e. the output transistor blocks or the
contactless switching output is open (safe condition).
Functional principle
The tuning fork is piezoelectrically energised and
vibrates at its mechanical resonance frequency of
approx. 1200 Hz. The piezos are xed mechanically
and are hence not subject to temperature shock
limitations. The frequency changes when the tuning
fork is covered by the medium. This change is
detected by the integrated oscillator and converted
into a switching command.

2.3 Storage and transport

Packaging
Your instrument was protected by packaging during
transport. Its capacity to handle normal loads during
transport is assured by a test according to DIN
EN 24180.
The packaging consists of environment-friendly,
recyclable cardboard. In addition, the sensor is
provided with a protective cover of cardboard.
Dispose of the packaging material via specialised
recycling companies.
3 Mounting

3.1 General instructions

Switching point
In general, LFV200 can be installed in any position.
The instrument simply has be mounted in such a
way that the tuning fork is at the height of the
desired switching point.
