What is an NTC?
An NTC is a semiconductor-based temperature sensor from the family of thermistors. NTC stands for “negative temperature coefficient”. The electrical resistance decreases exponentially with increasing temperature. This makes one of the most important differences compared to a linear probe like a Pt1000.
Characteristics of NTC Probes
Within a small temperature range – somewhere between -50 to 150 °C depending on the exact model – NTC have a high resolution and thus relatively high accuracy. They are also cheap and due to their high resistance values, you can use them with cables of any length as the cable resistance does not affect the measurement significantly. NTC are not standardized, so finding the right model may be a challenge which we are happy to help you with.
