LEVEL SWITCH 8110 • - contactless electronic switch
41765-EN-140211
It functions even under difficult conditions such as turbulence, air bub
-
bles, foam generation, buildup, strong external vibration or changing
products.
Function monitoring
The electronics module of LEVEL SWITCH 8110 continuously moni-
tors via frequency evaluation the following criteria:
•
Strong corrosion or damage on the tuning fork
•
Loss of vibration
•
Line break to the piezo drive
If a malfunction is detected or in case of power failure, the electronics
takes on a defined switching condition, i.e. the contactless electronic
switch opens (safe condition).
The tuning fork is piezoelectrically energised and vibrates at its me
-
chanical resonance frequency of approx. 1100 Hz. When the tuning
fork is submerged in the product, the frequency changes. This change
is detected by the integrated electronics module and converted into a
switching command.
LEVEL SWITCH 8110 is a compact instrument, i.e. it can be oper-
ated without external evaluation system. The integrated electronics
evaluates the level signal and outputs a switching signal. With this
switching signal, a connected device can be operated directly (e.g. a
warning system, a pump etc.).
The data for power supply are specified in chapter "
Technical data
".
3.3 Adjustment
The switching status of LEVEL SWITCH 8110 can be checked with
closed housing (signal lamp). Products with a density > 0.7 g/cm³
(0.025 lbs/in³) can be detected.
3.4 Storage and transport
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
