Description
ABB TVOC-2-240
Technical Specifications:
- Measured Parameter: Total Volatile Organic Compounds (TVOC)
- Model: TVOC-2 Series
- Output: 4-20 mA / Digital Communication
Functional Features:
- Continuous Monitoring: Real-time detection of VOC concentrations.
- High Sensitivity: Detects trace levels of organic compounds.
- Self-Diagnostics: Automated calibration and fault detection.
Application Scenarios:
Environmental emissions monitoring, indoor air quality control, and leak detection in chemical processing.
Performance Parameters:
- Detection Limit: Low ppb-level sensitivity.
- Response Time: Fast T90 response for rapid leak detection.
Material Composition:
Advanced sensor elements housed in a protective, corrosion-resistant enclosure.
Structural Features:
Standard industrial form factor with sample gas inlet and exhaust ports.
Working Principle:
Draws a sample of gas through the sensor cell, where VOC molecules are oxidized or detected via photoionization, generating a proportional electrical signal.
Installation Requirements:
Install in a location with representative gas sampling. Ensure proper sample conditioning (filtration, drying).
Usage Precautions:
Perform regular zero and span calibration. Avoid exposure to sensor poisons (e.g., silicones, lead compounds).
