Product catalog summary

Overview: The document provides technical specifications and features of the PAS Photoacoustic Gas Sensor for Ethylene (C2H4) with a measurement range of up to 1000 ppm. The sensor is designed for continuous operation and can be controlled via a connected PLC or operate autonomously.

Key Features:

Self-controlled or partially controlled operation.
Compact design with zero-calibration capability.
Continuous data access via UART data stream.
Automatic water vapor cross-sensitivity compensation.
24/7 operational design.

Applications: The sensor is suitable for gas analysis, biogas applications, environmental monitoring, process control, and emission monitoring.

Technical Specifications:

Measurement Principle: Photoacoustic.
Measurement Range: 0 to 1000 ppm Full Scale.
Flow Rate: 0.1 to 2.0 l/min.
Warm-up Time: ≤ 10 minutes.
Digital Resolution: 0.1 ppm.
Detection Limit: ≤ 5 ppm.
Repeatability: ≤ 1% of measured value plus ± 1.5 ppm.
Long Term Stability: Zero ≤ ± 1.5 ppm over 24 hours; Span ≤ 1% of value ± 3 ppm over 24 hours.

Electrical Parameters:

Power Supply: 12 Volts DC ± 1%.
Power Consumption: 45 Watts during heat-up, 15 Watts during operation.
Communication: TTL-UART and digital I/O’s.
Calibration: Zero-calibration by external command or automatic.

Climatic Conditions:

Operating Temperature: +10°C to +40°C.
Storage Temperature: +10°C to +40°C.
Air Pressure: 800 to 1150 hPa.
Ambient Humidity: 0 to 95% relative humidity (non-condensing).

Additional Information: The document notes that specifications are subject to change and recommends recalibration depending on application and ambient conditions. It also emphasizes the need for dry air or nitrogen purging of the housing to prevent condensation.
