Bedook Capacitive High-Temperature Sensor: An Outstanding Technology for Extreme Conditions

Characteristics of the Bedook Capacitive High-Temperature Sensor

1. High-Temperature Resistance

The Bedook Capacitive switch showcases exceptional resistance to high temperatures. Its Capacitive sensor probe, made of Teflon, ensures media detection at temperatures up to 230°C. In metal melting, ceramic sintering, and chemical production, this Capacitive proximity sensor performs flawlessly, maintaining accuracy under intense heat.

2. Separate Design of Sensor and Amplifier

This Capacitive proximity switch features a separate design for the sensor probe and amplifier. This flexibility simplifies installation and maintenance, particularly in complex environments. If a component fails, users can replace it without disassembling the entire Capacitive sensor unit, reducing downtime and costs.

3. High Protection Grade

With an IP66 rating, the Bedook Capacitive switch is resistant to dust and water. This protection is vital in industries such as coal-fired power plants and food processing, where environmental contaminants often pose challenges to traditional Capacitive proximity sensors.

4. Multiple Voltage Options

The sensor offers two models, Type I and Type II, compatible with diverse power systems. These options enhance the adaptability of the Capacitive proximity switch, ensuring seamless integration across various industrial platforms.

5. Energy Efficiency

The Bedook Capacitive High-Temperature Sensor demonstrates exceptional energy efficiency, with a no-load current of ≤50mA. Its ability to handle high maximum load currents (3A/30V DC, 3A/250V AC) makes it a reliable Capacitive proximity sensor for high-power applications.

Applications of the Bedook Capacitive High-Temperature Sensor

1. Electronic Manufacturing

In electronic manufacturing, precision and reliability are paramount, especially when working with high-temperature or viscous materials. The Bedook Capacitive High-Temperature Sensor ensures consistent performance in these scenarios:

• Chip Packaging: With a detection range of 1–10mm and high sensitivity, this sensor can accurately identify high-viscosity glues at temperatures up to 230°C, ensuring proper adhesive application during chip encapsulation. This reduces material waste and ensures reliable bonding for microchip assembly.
• Circuit Board Assembly: The sensor monitors solder flux levels and adhesive coatings, using its ±5% repeatability and hysteresis under 15% (Sr) to prevent defects like solder bridges or poor adhesion. Its IP66-rated design also protects against dust and contaminants commonly found in assembly lines.

2. Automotive Manufacturing

High-temperature conditions in automotive production processes demand robust and precise sensors:

• Engine Assembly: During gasket placement and sealant application, the sensor’s ability to detect adhesives at high temperatures ensures leak-proof engine components. The sensor’s Teflon probe, resistant to heat and chemicals, is ideal for such critical tasks.
• Exhaust System Manufacturing: Exhaust pipes and catalytic converters require high-temperature adhesives. The sensor accurately monitors adhesive quantities, ensuring uniform application for optimal product durability and performance under extreme exhaust temperatures.

3. Chemical Industry

Corrosive environments and extreme temperatures in chemical processing necessitate durable sensing solutions:

• Reaction Kettles: The sensor measures liquid levels in kettles containing high-temperature chemical solutions, aided by its stainless steel and Teflon construction. This ensures reliability even in corrosive or high-viscosity environments. With a maximum load capacity of 3A/30V DC or 3A/250V AC, it seamlessly integrates into process control systems.

4. Glass Manufacturing

The production of glass products involves precise handling of adhesives and bonding materials at elevated temperatures:

• Glass Forming Process: During the bonding of glass components, the sensor detects glue layers with a response frequency of 100Hz, ensuring precise application. Its IP66-rated housing shields it from dust and glass powder, preserving long-term functionality in demanding conditions.

5. Ceramic Industry

The ceramic manufacturing process, involving extreme heat and specialized adhesives, benefits from the sensor’s robust design:

• Ceramic Firing: The sensor monitors the application of high-temperature adhesives used in the assembly of ceramic tiles or components. Its operational range of -25°C to 70°C during standby and 230°C in use ensures reliability across the firing process, reducing defects caused by uneven adhesive distribution.

6. Food Processing

Though unconventional, the sensor’s high-temperature and chemical-resistant properties make it an excellent fit for detecting viscous or molten food ingredients:

• Chocolate or Syrup Coating: The sensor ensures precise application of molten chocolate or syrups, with its ±5% repeatability ensuring uniform coating and waste minimization. Its food-safe materials ensure compatibility with edible products, especially in high-temperature processes like baking or candy production.
