Safety Precautions:
Installation, initial start-up and maintenance may only be performed by trained personnel!
The device may only be connected to power which complies with the specifications included in the technical data and on the
serial plate!
The device must be disconnected from all sources of power during installation and maintenance work!
The device may only be operated under the conditions specified in the operating instructions!
Functions Description:
TURBISWITCH GS4
evaluation unit with required measuring sensor for installation in piping,
TURBISWITCH GA1, GA5, GA11
or
TURBISWITCH CP2
immersion probe
Turbidity measurement is based on the absorption process, i.e. it reacts to reduced light due to suspended sediment in the
liquid. Measurement is insensitive to extraneous light thanks to the use of pulsed infrared light. Measuring sensitivity depends
on the length of the measuring section. The shorter the measuring section, the more turbid the liquid can be.
Pulsed infrared light is transmitted from the emitter through the liquid to the receiver. If the selected turbidity value is exceeded
or fallen short of, the output relay in the switching amplifier reacts.
Digital communication between the devices
Turbidity dynamics for the overall sensing range: >100dB
Measuring sensor for installation in piping: max. roughly 10,000 FAU (depending on diameter)
Immersion probe for open containers or troughs: max. roughly 30,000 FAU
3 adjustable measured value ranges (low / medium / high)
1 floating changeover contact
(both contacts are open when supply power is switched off)
1 floating alarm output contact

Attention! Operation of the previous version of the turbidity emitter and receiver (TT-GS and TR-GS), as well as the CP1
immersion probe, is only possible with the TRUBOMAT GS3 turbidity limit monitor.
