Marathon Quicksilver Alloy Oxygen Probe FC8600

1. Product Overview

Model: FC8600 (part of Marathon Sensors' Quicksilver series)

Type: High-Temperature Oxygen Sensor (ZrO2), designed specifically for measuring oxygen content in molten metals (such as aluminum, copper, zinc alloys).

Application Scenarios: Casting, metal heat treatment, metallurgical industry, used for real-time monitoring of oxygen partial pressure in furnaces or molten metals to optimize process control.

2. Key Features

Quick Response: The Quicksilver series is renowned for its rapid and stable readings, ideal for dynamic melting environments.

Alloy Compatibility: The probe material is resistant to high-temperature corrosion and suitable for non-ferrous alloys such as aluminum and copper.

Temperature Range: Typically supports 600°C to 1200°C (specific details may vary by model, please refer to manual).

Output Signal: Analog signal (such as 4-20mA or mV) or digital interface, compatible with most controllers.

3. Installation and Maintenance

Installation Points:

Insert to the specified depth in the furnace or metal liquid (refer to the user manual).

Ensure airtightness to prevent air leakage affecting the reading.

Calibration: Regularly calibrated with standard gas (such as N/O2 mixed gas with known oxygen concentration).

Service Life: Depends on the operating environment; continuous operation at high temperatures may shorten the service life.

4. Troubleshooting Common Issues

Unstable readings:

Check if the probe is aging or contaminated.

Ensure the reference air channel is clear (external reference gas required for some models).

No signal output

Verify power/source wiring usually requires 24 DC power supply).

Check if the probe has reached the working temperature (some require external heating preheating).

5. Alternative and Compatibility

Replacement Model: Marathon may offer an updated model (such as FC8700).

Warranty: 12 months
