Product Introduction

1. Product Overview‌
‌Brand and Model‌: SIEMENS ULTRAMAT 23 Series Infrared Gas Analyzer, Model ‌7MB2337-0NH00-3PG1‌‌13.
‌Measurement Principle‌: Adopting ‌Non-Dispersive Infrared (NDIR) technology‌, combined with ‌electrochemical sensors‌, high-precision detection of multiple components is achieved through the absorption characteristics of gas to infrared light of a specific wavelength‌47.
‌Core Function‌: Supports simultaneous measurement of ‌3 infrared sensitive gases (such as CO, CO₂, NO, SO₂, CH₄, etc.)‌ and ‌Oxygen (O₂)‌, and some configurations can be expanded to four-component analysis‌46.
2. Technical Parameters‌
‌Measurement Range‌: Customized according to gas type (such as CO: 0-5% vol, SO₂: 0-5000 vpm)‌.
‌Accuracy‌: Resolution <0.01 vpm (H₂S), measurement value drift <2% small range/week‌.
‌Response time‌: ≤10 seconds (T90)‌.
‌Output interface‌: RS-485, RS-232, Profibus, support remote data transmission and monitoring‌.
‌Power supply and protection‌: 230 V AC, 50 Hz; 19-inch pull-out design, protection level IP65, suitable for control cabinet installation‌.

3. Core features‌
‌3.1 Multi-component measurement capability‌
-- Can analyze 3 infrared gases + oxygen at the same time, reduce cross-interference and improve selectivity through multi-layer detector design‌.
‌3.2 Intelligent maintenance‌
-- Support automatic calibration of ambient air (zero point calibration), only one standard gas verification is required per year, reducing maintenance costs‌. ‌

3.3 Industrial-grade reliability‌
-- Adopting corrosion-resistant material gas chamber and anti-vibration design, it can adapt to harsh industrial environments such as high temperature and high dust.
3‌.4 User-friendliness‌
-- Equipped with a plain text menu operation interface and a wireless handheld operator, it supports remote operation and log recording for easy maintenance.
4. Typical application scenarios‌
4‌.1 Industrial emission monitoring‌: Real-time monitoring of CO, NOx, and SO₂ in flue gas from coal-fired/gas-fired boilers and incinerators.
‌4.2 Process control‌: Gas concentration and calorific value measurement in chemical production, biological fermentation, and landfills.
‌4.3 Safety protection‌: Early warning of combustible/toxic gas leakage in coal powder silos and sewage treatment plants.
‌4.4 Environmental monitoring‌: Accurate detection of harmful gases (such as SO₂ and NOx) in the atmosphere and water quality.
5. Precautions for use‌
‌5.1 Installation requirements‌: A pre-filter and dehumidification device must be configured to prevent particulate matter or moisture in the sample gas from contaminating the sensor‌.
‌5.2 Calibration specifications‌: Oxygen calibration depends on ambient air, and infrared components need to be verified regularly using standard gas‌.
‌5.3 Compatibility restrictions‌: The paramagnetic oxygen measurement version is not suitable for emission monitoring scenarios, and the electrochemical sensor version needs to be selected according to needs‌.

6. Product advantages

-- Automatic calibration with ambient air (depending on the measured component)

-- No need to use calibration gas, saving costs

-- Multi-layer detector with high selectivity, for example, reducing cross-interference caused by water vapor

-- Cleanable sample pool to extend the service life of the instrument.

-- The analyzer uses micro-flow detector measurement technology, which is small in size, highly sensitive and not afraid of vibration.

-- Menu-assisted operation in simple text format

-- Service information and records

-- Open interfaces (RS 485, RS 232, PROFIBUS, SIPROM GA):

-- Easy integration and remote control
