Scope

Scope: This document specifies the requirements, test methods, inspection rules, marking, packaging, transportation, and storage for single-ended plug-in ammonia online monitoring systems. This document is applicable to single-ended plug-in ammonia online monitoring systems in industrial parks. Main technical contents: Reproducibility: ±1.0% FS (measurement component, range) Linearity: ±1.0% FS (measurement component, range) Zero drift: ±1.0% FS/6 months (measurement component, range) Other gas interference: In principle, there is no interference from gases that do not absorb within the measurement wavelength range. Response time (90% FS response): less than 5 seconds. Preheating time: within 30 minutes. Analysis method: Based on the principle of selective absorption at characteristic wavelengths. Instrumental air requirements: 0.4-0.7 MPa. Alarm output: Outside the set gas temperature range, abnormal low pressure of instrument air, and abnormal temperature inside the enclosure. Output signal type: 4-20 mA.
