Thermistors with terminal head - Technical Information What Are Terminal Heads? Terminal Heads are a type of cold end termination which are common on industrial type temperature sensors. A temperature sensor will be encased in a ceramic or metal sheath which will be terminated at the cold end with a terminal head. Inside the head, terminal blocks or temperature transmitters are placed to carry the sensor signal to instrumentation. What is an RTD sensor? An RTD (Resistance Temperature Detector) is a type of sensor used to measure temperature. RTDs are used for accurate, stable and reliable...

Thermistors with terminal head - Technical Information What is the difference between an NTC and a PTC? RTDs advantages RTDs have several advantages over other types of temperature sensors: NTCs and PTCs are both thermistors, i.e. temperature sensors that change resistance depending on the temperature. However, There is a major difference between these two types of thermistors: High precision RTDs have high temperature sensitivity, typically in the range of 0.1 to 0.2% per °C, allowing for accurate temperature measurement. Long term stability RTDs have long-term stability and longer life...

Thermistors with terminal head - Technical Information The β beta value A thermistor’s “β” value, or beta value, is an indication of the shape of the curve representing the relationship between resistance and temperature of an NTC thermistor. Where: Rt1 = Resistance at Temperature 1 Rt2 = Resistance at Temperature 2 T1 = Temperature 1 (K) T2= Temperature 2 in (K) Calculating the beta value is a vital step in the component selection process as it gives the characteristic at a given temperature vs the resistance for a specific application. The beta value of an NTC Thermistor is calculated...
