Laser contamination monitoring sensor
Get instant clarity about the condition of your oils and fuels: contamination, moisture and temperature | micfil laser contamination monitoring sensor.
The universally applicable micfil laser contamination monitoring sensor (CMS) automatically measures and displays particulate contamination, moisture and temperature levels in various hydraulic fluids.
It is designed specifically to be mounted directly to systems, where ongoing measurement or analysis is required, and where space and costs are limited.
The micfil CMS measures water content using a capacitive RH (relative humidity) sensor. The result is expressed as percentage saturation. 100% RH corresponds to the point at which free water exists in the fluid, i.e. the fluid is no longer able to hold the water in a dissolved solution.
All micfil CMS units are supplied with software to download automatically new results as they are generated, provided the test is done while being directly controlled by the software.
Or alternatively historical results can be downloaded from the CMS inbuilt memory. When the memory is full, the oldest log entry is overwritten automatically: Which tests are logged, and when, are determined by the log settings. Each log entry is time-stamped and contains the CMS serial number, so that it can be identified later.
Features:
- Measures and displays the international standard formats: ISO 4406:1999, NAS 1638, AS 4059E and ISO 11218.

Extended products for micfil CMS installations
Connection of a micfil CMS (right) to a laptop via CMS-USB-I Connector.
CMS-USB-I Connector
This is a ready-made solution for easily connecting a PC/Laptop to the micfil CMS. It comprises of a USB:RS485 interface with a terminal block pre-wired to connect directly to the CMS. An extra terminal block is provided for any customer wanting to wire to external devices through two solid state relays. An external DC adapter can be used to power the complete system, or if the computer is always connected during use, power can be taken directly from the USB cable. Powered PC/Laptops only.
Cms-rdu
The CMS-RDU is a separate product that is used to remotely monitor or control a CMS when the CMS is out of reach in a location unsuitable for viewing.
CMS-FC1
A pressure compensated flow control valve specifically designed to fit the CMS. This may be needed if the application produces an oil flow greater than 400 ml/min. The CMS-FC1 is supplied with adaptors which enable the valve to be fitted to the CMS. The valve outlet port has a mini mess fitting installed as a standard option.
