Focusens Bullet Type NTC Temperature Sensor 10K 3950 for Coffee Machine
The Focusens Bullet Type NTC Temperature Sensor (10KΩ, B=3950) is a compact, high-precision thermal probe engineered for integration into coffee machines and other beverage equipment. It provides accurate temperature feedback for process control systems, featuring a robust design suitable for direct immersion in liquids.
Features
- Bullet-type NTC thermistor with 10kΩ resistance at 25°C (R25) and Beta (B) value of 3950K.
- Wide operating temperature range from -25°C to +105°C, suitable for hot beverage applications.
- Low thermal mass and fast response time (time constant ≤100 seconds) for dynamic temperature tracking.
- Compact cylindrical design facilitates easy installation and immersion in liquid reservoirs or heating blocks.
- Maximum power rating of 60mW with a dissipation factor of approximately 5.6 mW/°C for stable, self-heating-minimized operation.

This sensor utilizes a Negative Temperature Coefficient (NTC) thermistor element, where electrical resistance decreases predictably with increasing temperature. The specified 10KΩ @ 25°C resistance and 3950 Beta value define its precise temperature-resistance curve, enabling accurate temperature measurement through simple voltage divider circuits or dedicated thermistor input modules on microcontrollers (Arduino, ESP32, Raspberry Pi) or industrial PLCs.
Encased in a durable, bullet-shaped stainless steel probe, it is designed for direct contact with liquids in coffee machines, ensuring reliable thermal transfer. The low dissipation factor minimizes self-heating errors, while the robust construction withstands the thermal cycling and moist environments typical of brewing systems.
