Polyimide Heater with PT100 Sensor for Precision Thermal Management

In industries where precise temperature control is critical—such as semiconductor manufacturing, medical devices, and aerospace—a reliable heating solution can make all the difference. The Polyimide Heater with integrated PT100 Temperature Sensor provides an ultra-thin, flexible, and high-performance solution for applications demanding accuracy, durability, and safety.

This blog explores why this combination is ideal for thermal management and how it outperforms traditional heating methods.

Why Choose a Polyimide Heater?

1. Ultra-Thin & Flexible Design

Made from polyimide film (Kapton®-like material), these heaters are lightweight and can conform to curved or irregular surfaces.

As thin as 0.1mm, they fit into compact spaces where bulky heaters can’t.

2. High-Temperature Resistance

Operates reliably from -50°C to +260°C (or higher with special designs).

Resistant to chemicals, moisture, and mechanical stress.

3. Fast & Even Heating

Low thermal mass allows for quick heat-up and cool-down times.

Uniform heat distribution prevents hot spots, improving process consistency.

The Role of PT100 Sensors in Precision Control

1. What is a PT100 Sensor?

A platinum resistance thermometer (RTD) that provides highly accurate temperature readings.

The "100" refers to its 100-ohm resistance at 0°C.

2. Why Use Dual PT100 Sensors?

• Redundancy for Safety – If one sensor fails, the backup ensures continuous monitoring.

• Cross-Verification – Two sensors confirm temperature readings, preventing overheating errors.

• Linear Response – Resistance changes predictably with temperature, improving control accuracy.

3. Key Benefits of PT100 in Thermal Systems

High accuracy (±0.1°C to ±0.5°C)

Stable performance over time (no drift like thermocouples)

Works in harsh environments (vibration, EMI-resistant)

Applications of Polyimide Heater + PT100 Sensor

1. Medical & Laboratory Equipment

PCR machines, incubators, and diagnostic devices requiring stable heating.

2. Semiconductor & Electronics Manufacturing

Wafer processing, 3D printing nozzles, and PCB preheating.

3. Aerospace Automotive

Battery thermal management, de-icing systems, and sensor calibration.

4. Industrial Automation

Plastic molding, packaging machines, and food processing.

A Smarter Heating Solution for Demanding Applications

The Polyimide Heater with PT100 Sensor is an ideal choice for industries that need:

• Precise temperature control (thanks to PT100’s accuracy)

• Flexibility & durability (polyimide withstands tough conditions)

• Safety & reliability (dual-sensor redundancy prevents failures)

Whether you’re designing medical devices, semiconductor tools, or advanced battery systems, this combination ensures efficient, stable, and long-lasting thermal performance.
