Thermistors for use with Digital Thermostats
We supply a range of PTC and NTC thermistor sensors for use with our digital thermostats. Our standard range is designed for temperatures ranging between -50C to +150C, depending on the sensor and are available with a choice of materials and tube diameters. Custom PTC and NTC sensors can be designed for specific applications.
Key characteristics of PTC sensors:
Resistance increases with increasing temperature.
Used in self-regulating heating elements, temperature sensors, and protection devices.
Applications include heaters, automotive cooling systems, and thermal switches.
Key characteristics of NTC sensors:
Resistance decreases with increasing temperature.
Used in temperature measurement and control systems.
Applications include thermostats, HVAC systems, medical devices, and automotive temperature monitoring.
In summary, the main difference between PTC and NTC sensors lies in their response to temperature changes. PTC sensors have a positive temperature coefficient, meaning their resistance increases with increasing temperature, while NTC sensors have a negative temperature coefficient, with resistance decreasing as the temperature rises. The specific choice between PTC and NTC sensors depends on the application’s requirements and the desired temperature-sensing characteristics.
