5 Description
The CS 1000 Series Contamination Sensor is a stationary measurement unit for the
continuous monitoring of particulate contamination in hydraulic and lubrication systems.
The CS is designed for connection to low- or high-pressure hydraulic and lubrication lines
and testbenches from which a small flow of oil (between 30 ml/min and 300 ml/min) is
diverted for measurement purposes. The contamination sensor is suitable for pressure
ranges up to 100 bar and viscosities up to 1000 mm²/s.
Particulate contamination is detected using an optical measurement cell.
Measurement results can be output as contamination code according to ISO 4406 : 1999 or
SAE AS 4059 (D) (cleanliness classes: >4 µm( c) >6 µm( c) >14 µm( c)>21 µm( c)).
The sensor is available with the following options:
•
with or without 6-digit display and keypad (the display can be rotated by 270°) — see
section 6.2.1 )
•
with a 4 – 20 mA or 0 – 10 V analog output
•
pipe / hose mounting or flange mounting (see section 5.4.1 or 5.4.2)
All models feature an analog electric output and an RS485 interface for outputting the
measured contamination levels. Additionally, an electronic switching output can be
configured to alert the operator about rising or falling contamination levels.
5.1 Restrictions
Pertaining to the Use of the CS
The CS 1xx0 is qualified for mineral oils (or mineral-oil-based raffinates).
The CS 1xx1 is qualified for phosphate esters.
Please contact us first before using the unit with other fluids.
