2.2 Device description

The sensor is designed to measure suspended solids concentrations in liquids. Combined with the MAC 080 converter, the sensor is used to measure suspended solids content as a function of the ability of suspended materials to absorb and reflect NIR-light (Near Infrared). The sensor is available in two versions, for inline mounting and for submersion.

This manual details installation procedures and operational features of the sensor. Menu navigation and technical data for the converter can be found in the converter manual.

www.krohne.com 07/2010 - MA OAS 2000 R02 en

OPTISENS OAS 2000

2.2.1 Design

The sensor is manufactured with 316SS (SS2343) Stainless Steel. The head of the sensor is designed to achieve the highest self-cleaning effect, providing an exact and reliable measurement with the least possible maintenance under critical applications. The measuring lenses within the housing are made of glass. The electronics and optics are protected in the rugged casing, ensuring its reliability in very demanding environments.

The sensor has a fixed, shielded 10 m / 33 ft cable used for signal transmission between the sensor and the converter. The cable sheath is made of Hytrel and is highly resistant to aggressive materials and fluids.

The inline version of the sensor has a M12 connector to connect a standard OPTISENS 2000 cable to the converter.

INSTALLATION 3

3.3 Configuration of a measuring point

A complete measuring point consists of at least three parts:

• MAC 080 converter

• OPTISENS 2000 sensor (including cable)

• MAA 2000 sensor holder

If automatic flushing is installed, an optional solenoid valve is necessary as well.

Examples of typical measuring points are listed in the following sections.

The figure above shows a single parameter measuring point consisting of one converter 1, one sensor 4 with a telescopic rod immersion assembly as sensor holder 3 and one solenoid valve 2 for flushing.

The spring loaded mounting bracket for installation of the telescopic rod sensor holder on the handrail is included in the delivery of the holder and can be used for round and square hand rails with a maximum diameter of 50 mm / 2".

The signal cable to the sensor and the flush hose are provided with the sensor.

The mounting plate with sun shield and the mounting post are available optional.
