up to NG1000; up to PN 0.5; T = -40 °C to +160 °C
1. DESCRIPTION
1.1. GENERAL
FSA uid level gauges, FSK uid level
sensors and TS temperature switches
are designed to monitor and control the
level of operating uid.
The exible product range means that
many combinations are possible:
– FSA: Range of eleven evenly spaced
sizes.
Visual thermometer with °C and °F
scale.
Temperature gauge which measures
the temperature of the operating uid
in the tank in °C. Dual scale in °C and
°F available on request.
Simple standardised installation
conditions.
– FSA-IB: shut-off of the uid to the uid
level gauge via non-return valve.
Display of the current level by
simultaneously pressing the upper
and lower buttons on the non-return
valves.
With the optional use of a
thermometer, the current temperature
of the uid will also be shown.
Certied by Bureau Veritas
(BV approval) and by American
Bureau of Shipping (ABS approval).
– FSAR: Fluid level gauge in round
design with pipe connections on both
sides.
Thanks to the principle of
communicating vessels, the gauge
can be attached externally even at
greater distances.
– FSK: Monitor the uid level via an
electrical signal.
Range of eleven evenly spaced sizes.
Simple standardised installation
conditions.
Switching contact (sizes 127-381)
designed as optionally normally
closed (type O), normally open (type
C) or changing (type W) contact – as
changing contact (W) in sizes 076 and
500-1000.
Temperature gauge which measures
the temperature of the operating uid
in the tank in °C and °F.
Option: line marking on sight tube and
oat.
Better visual uid level monitoring
possible with red oat.
– FSK-2SP: Monitoring of the minimum
or maximum uid level.
Two additional alternative switching
points for size 254 and above.
Optional: line markings on inspection
tube.
– FSK-V: Switch points can be
positioned variably, additional
alternative switch points possible.
Switching contact designed as
changing contact, opens or closes at
switching level.
Riser tube made of glass.
Optional, 3-pole AMP plug
(Super Seal).
Optional: line markings on inspection
tube.
– TS: three nominal temperatures
possible: 60 °C, 70 °C and 80 °C.
Can be easily tted into the FSA and
FSK.
Simple, standardised mounting
(FSA/K).
Non-corroding surfaces.
– Accessories
TFP 100: Temperature sensor with a
measurement range of
-40 °C to +125 °C.
Measuring resistor designed as
4-conductor with standardised
electrical connection.
ABK / ABV: These shut-off elements
allow the connections to be blocked
for maintenance work or for making
changes to the display system (FSA/
FSK), without any tank draining
required.

ABK
This stop cock specially designed for the
FSA/FSK has a plug that is guided in a
valve casing and that can be turned from
the outside. Turning it by 90° closes the
connection opening of the FSA/FSK.
It is operated by screwdriver, from the
side, above or below depending on the
position of the ABK.
ABV
Screwing the adjusting screw deeper
into the valve casing closes the
connection opening of the FSA/FSK
(the screw can be loosened again
subsequently).
The screw is adjusted by means of an
allen key (AF width 3).
1.2. FUNCTION
FSA
By using the FSA, the uid level can be
easily seen on the outside of the tank.
The uid enters the unit via the lower
connection bore and is clearly visible in
the tube. By selecting the right size, the
particular uid level can be monitored.
FSK
By using the FSK, the uid level is
monitored via an electrical switching
signal. This switch signal can be used
for a warning or to control the level.
The uid enters the unit via the lower
connection bore and pushes a oat up
the tube. The oat now shows the level
of the uid in the tank. If the level of the
uid drops again, the oat will activate a
switch contact. For the NO switch (type
C) the circuit will then be closed, for the
NC switch (type O) the circuit will be
opened.
The special dual switching model (type
W) offers two possibilities. It can be used
either to close on contact or to open on
contact.
TS
The TS is a very useful additional option
to the FSA and FSK products. However,
it also has a useful application as a
separate accessory for systems.
Once tted, the temperature sensor
of the TS is surrounded by operating
uid. When the nominal temperature is
reached, a contact opens and the circuit
is broken.
This switching process can be used
either as an alarm or to monitor the
temperature.
When the temperature of the uid drops
by approx. 15 K, the circuit closes again.
TFP
Based on the principle of voltage drop,
the sensor provides an electrical signal
as a value for the temperature.
A constant measurement ow is
fed to the temperature sensor. The
voltage change is roughly proportional
to the change in resistance caused
by the temperature – the higher the
temperature, the greater the resistance.
Measurement errors caused by longer
feed lines are avoided by using the
4-conductor connection.
1.3. APPLICATION
Fluid level gauges FSA, uid level
sensors FSK and temperature switches
TS are used to monitor and control levels
of operating uid.
Areas of application are for example:
Machine tools, system engineering, tanks
for hydraulic, lubricating and cutting oils,
and gearboxes.
1.4. NOTES
The upper viscosity limit is 2,000 mm²/s.
It is not possible to combine a TS
temperature switch with an FT
temperature gauge.
To ensure correct functioning, pressure,
viscosity and temperature specications
must be observed.
FSA/FSK
In the standard design not suitable for
use with glycol and uids containing
glycol – the special design SO14 is
recommended as a solution variant in
such cases.
FSK
Depending on the uid level of the tank,
the following switching logic applies for
the uid level monitor with NC and NO
contacts.
Tank uid level
Tank uid level
(normally
closed)
(normally
open)
In each case the switching logic of the
uid level sensor starts with a full tank.
For the NC version the switching contact
opens when the uid level drops below
the switching level. Correspondingly, in
the NO version, the switching contact
closes when the uid level drops below
the switching level.
