Description

The HaiWang MF58 NTC thermistor operates on the principle of a negative temperature coefficient, where its electrical resistance decreases predictably as temperature increases. This precise R-T characteristic, defined by its 50KΩ base resistance and 4150 B-value, allows for accurate temperature sensing across a wide operational range. The sensor’s robust glass encapsulation protects the ceramic element from moisture and chemical contaminants, ensuring long-term stability and reliability in demanding applications.

Designed for seamless integration into control systems, the MF58 provides a simple, analog voltage-divider output compatible with microcontrollers (Arduino, Raspberry Pi, ESP32), PLCs, and dedicated instrumentation amplifiers. Its fast thermal response and high sensitivity make it ideal for applications requiring rapid feedback loops, from HVAC control to battery thermal management and industrial process monitoring.

Frequently Asked Questions

What is the base resistance and B-value of this NTC thermistor?

This HaiWang MF58 thermistor has a nominal resistance of 50 kilo-ohms (kΩ) at 25°C and a B-value (Beta) of 4150K, calculated between 25°C and 85°C. These parameters define its precise resistance-temperature (R-T) curve for accurate temperature measurement.

How do I interface this thermistor with a microcontroller like Arduino?

Interface the thermistor by creating a voltage divider circuit. Connect the thermistor in series with a fixed precision resistor (e.g., 50kΩ) between your microcontroller's supply voltage (3.3V or 5V) and ground. Connect the junction point to an analog input pin. Use the Steinhart-Hart equation or a lookup table in your code to convert the measured voltage into temperature.

What are the advantages of the glass encapsulation?

The glass encapsulation provides a hermetic seal, protecting the sensitive ceramic NTC element from moisture, dust, and chemical vapors. This significantly enhances long-term stability, prevents resistance drift in high-humidity environments, and improves durability in harsh industrial or automotive applications compared to epoxy-coated or bare thermistors.

What is the typical response time of this sensor?

While specific response time depends on the thermal mass of the system and mounting, the MF58's small glass bead construction and direct thermal coupling offer a fast thermal response. This makes it suitable for applications requiring rapid temperature feedback, such as overheating protection in power electronics or real-time climate control systems.
