详情描述

The Lambda oxygen probe (such as the Lambda series) from Germany's MESA company is a high-precision gas sensor widely used in industrial combustion control, automotive exhaust monitoring, and environmental protection. It is primarily used to measure oxygen concentration (O?) or air-fuel ratio (λ value). Below are the key details about this product:

1. Core Functions and Principles

Measurement Object: Oxygen Concentration (O2) or Air/Fuel Ratio (λ value).

Technical Principle: Based on the electrochemical principle of zirconia (ZrO2), it calculates the oxygen partial pressure through the migration of oxygen ions under high temperature, generating an electrical potential difference.

Typical Applications:

Combustion optimization for industrial boilers and kilns.

Automotive exhaust emissions monitoring (e.g., lambda sensor).

Chemical Process Control

2. Product Features

High Temperature Resistance: Zirconia sensors need to be heated to several hundred degrees Celsius for operation (such as above 600°C), with built-in heating elements.

High precision: Measurement range typically covers 0.1%~25% O2, with λ value accuracy up to ±0.01.

Rapid Response: Millisecond response time, suitable for dynamic control.

Durable: Corrosion-resistant design, suitable for harsh industrial environments.

3. Model and Selection

Common models may include:

Lambda Pro: Industrial-grade high-precision probe.

Lambda Mini: Compact, suitable for space-limited environments.

Automotive-specific lambda sensors (such as wideband oxygen sensors).

4. Installation and Maintenance

Installation Requirements:

Avoid mechanical vibration or thermal shock.

Calibrate gases (such as standard gases with known oxygen concentrations) on a regular basis.

Maintenance:

Regularly clean the probe surface of carbon or contaminants.

Inspect the heating element functionality.

5. Frequently Asked Questions

Signal Drift: May be due to aging or contamination, requires calibration or replacement.

Life span: Typically 1-5 years, depending on the usage environment.
