Temperature Sensors - NTC Thermistors

09M3002JF Application Field and Working Principle

NTC thermistors are thermistor sensors used for temperature measurement. The nine models of the 09M series offer central bore diameters ranging from 3.3 mm to 14.2 mm with varying resistances at 25°C from 0.1Ω to 32.5kΩ. They are made of ceramic materials, with nickel-alloy wire with PTFE/PVC insulation and a tinned copper lead wire, and offer excellent long-term stability.

The 09M-series NTC thermistors offer an economical alternative to standard thermistors, and are used in a variety of temperature-sensitive applications, including:

• Automotive, Industrial, Medical, Aerospace & Avionics
• HVAC, Refrigerator and Air Conditioning controls
• Refrigerator and Freezer Control
• Heating and Cooling Systems Control
• Battery Management Systems
• Computer and Telecom Equipment
• Computer Motherboards & Hard Drives
• Food Processing & Preparation Equipment
• Medical Equipment
• Industrial Control and Automation
• Safety and Security Systems

The 09M-series NTC thermistors are based on the reference industrial standard for use of these devices in the temperature range of -30°C~125°C. They are used for the temperature measurement of liquids, gasses, and ambient air. These thermistors are calibrated using the room temperature coefficient 0.385 and offer resistance values of 0.1 to 32.5K ohms. In addition, these thermistors are tested for their voltage, current, thermal stability, and insulation parameters according to their individual specifications.

The basis of their operation is that the resistance of these thermistors decreases as the temperature increases due to the semiconductor effect. This is a phenomenon in which the thermal energy affects the movement of the electrons. In a NTC thermistor, the electrons move away from the positive terminal and move towards the negative terminal when heated. As NTC thermistors have a negative temperature coefficient, the resistance decreases with an increase in temperature.

Furthermore, the 09M-series NTC thermistors are highly responsive and can detect a small change in temperature due to their accurate temperature coefficient and their rapid response time. As a result, the temperature change can be measured accurately, and the thermistor can be used for temperature control applications. In addition, they possess excellent reliability, temperature stability, and wide temperature range.

In summary, the 09M-series NTC thermistors are low cost, accurate, reliable, highly sensitive devices used for temperature measurement and control. They offer excellent long-term stability, good temperature accuracy, and are used in a wide range of temperature-sensitive applications.
