The TURBISWITCH GS4 is designed to be used with our immersion probe CP2 or our turbidity armatures GA1 ... GA5. It provides a contact signal as soon as the turbidity reaches the pre-set value. A complete system compares continuously the measured value with the pre-set value; it is not pre-calibrated in factory but calibrated on site by end-user. The technician on site configures the instrument using samples to calibrate the limit for switching the output between correct turbid sample and overpass turbidity value. Most of all products can be monitored, even with high load, small or big particles. 

A complete turbidity control system includes:

   1 turbidity controller TURBISWITCH GS4
+ 1 immersion probe CP2 with built in emitter and receiver (data sheet 425-02)
 
Or

   1 turbidity controller TURBISWITCH GS4
+ 1 armature TURBISWITCH  GA... for in-line detection or by-pass fitting,
with pipes from ND 15 to 125 (data sheet 422-01), with built in emitter and receiver  

- Control on phase separation milk/ water
- Control on CIP process
- Survey on separation, centrifugation... process
- Pollution control

The emitter TT-HDR (High Dynamic Resolution) sends an infra-red beam (860 nm) through the fluid to the receiver TR-HDR.

The signal variations due to the turbidity are fully used by the TURBISWITCH to detect the over passing pre-set value. To avoid false alarms due to air bubbles or accidental excess of turbidity, timers are adjustable from 0.1 to 9.9 seconds (increasing and decreasing turbidity).
