DCEM1001 Single-pass Optical Dust / Opacity Monitor

Product catalog summary

Overview: The D-CEM1000/1001 Opacity Monitors are designed for measuring opacity, extinction, or dust density in industrial environments. They consist of a visible light transmitter and receiver with digital data processing capabilities.

Key Features:

Displays data in opacity, extinction, or dust density (mg/m³ or mg/Nm³).
Includes four analogue inputs for normalization data: temperature, oxygen, pressure, and water vapour (D-CEM1001 model).
Simple installation, high reliability, and low maintenance.
Minimized lens contamination through high-efficiency air purges.

Power and Construction:

Power supply: 76V to 265V AC at 50/60Hz, 20VA.
Construction: Epoxy-coated aluminium, IP67 rated.
Operating temperature: -20°C to +70°C.

Inputs and Outputs:

Analogue outputs: 2 x 4-20mA current outputs, isolated, 500Ω load max.
Logic outputs: 2 x volt-free SPCO contacts, configurable as alarm contacts.
Inputs: 4 x 4-20mA for normalization data (D-CEM1001 only).

Measurement Specifications:

Operating principle: Single pass transmissometer.
Light source: Modulated high-intensity LED at 637nm wavelength.
Span: Selectable in % opacity, extinction, mg/m³, and mg/Nm³.
Averaging: 4 rolling averages selectable from 10 seconds to 30 days.
Accuracy: ±0.2% opacity.
Drift: Less than 1% opacity per month.
Resolution: 0.1% opacity.
Optical path length: 0.5 - 15m.

Compliance:

EMC: Compliant with 89/336/EEC directive.
Low Voltage: Compliant with 73/23/EEC directive.

Additional Options:

Heated flanges to prevent condensation on lenses.
