Insertion Turbidity Probe Model AP2
Description:
The turbidity probe model AP2 measures the NIR- absorption caused by turbidity in liquids.
Configurable to measure:
ppm, mg/l, EBC, FTU, g/l, %, AU, Ext, OD, ….
Measuring principle Turbidity Probe:
The probe uses the principle of NIR- absorption to detect turbidity in liquids. An LED light source with emission in the near-infrared range and a high-precision receiver diode are installed in the sensor’s optics.
The measurement in the infrared spectrum ensures precise measurement results, unaffected by fluctuations in product color.
Properties Turbidity Probe Model AP2:
Calibration / maintenance interval typically 12 months (depending on application):
– Less maintenance and longer service life.
– Service life of the LED light sources, typically 5 years.
Probe material typically stainless steel 1.4404 (optional titanium, Hastelloy, …):
– The wetted parts of the probe are made of stainless steel.
-Other materials such as titanium or Hastelloy are optionally available.
Measuring window: Sapphire (optionally borosilicate, Plexiglas, …):
– Sapphire is used as the window material.
– Other materials such as borosilicate or Plexiglas are optionally available.
Sealing material: FKM (optionally FFKM, EPDM, silicone, …):
– The seals are made of FKM.
– Seals made of other materials such as FFKM, EPDM or silicone are optionally available.
Process connection:
Installation through ball valve in process line.
– Tuchenhagen Variline measuring cell, probe with Varivent plate.
– DIN or Ansi flange on the probe shaft.
Measuring range span: 0 – 0.1 AU up to 0 – 5 AU:
-The measuring range extends from 0 to 0.1 absorption units up to 0 – 5 absorption units.
