Resistance thermometers on the basis of Pt100, Pt1000 (positive temperature coefficient PTC) and NTC (negative temperature coefficient) are used everywhere in the industrial temperature measurement where low to medium temperatures are measured. In the process industry, Pt100 and Pt1000 sensors are used almost exclusively. Positive Temperature Coefficient (PTC) A PTC thermistor is one in which the zero-power resistance increases with an increase in temperature. The linear relationship between temperature and resistance simplifies the designer’s task in that the characteristic non-linear curve needs no normalization. The second group is the switching type PTC thermistor. This type of PTC thermistors is widely used in PTC heaters, sensors etc. Polymer PTC thermistors, made of a special plastic, are also in this second group, often used as resettable fuses. The switching type PTC thermistor has a highly nonlinear resistance-temperature curve. 3 Sensor Type 1. 100 ohm Platinum RTD Celsius Temp Resis Temp Resis Temp Resis Temp Resis-40 84.27 11 104.29 62 124.01 113 143.42-39 84.67 12 104.68 63 124.39 114 143.80 Temperature vs Resistance Conversion Chart for 10k Thermistors °F OHMS °F OHMS °F OHMS °F OHMS °F OHMS °F OHMS °F OHMS -50 491,142 0 85,387 50 19,900 100 5,827 150 2,044 200 829 250 378 -49 472,642 1 82,719 51 19,377 101 5,697 151 2,005 201 815 251 373
The range includes various models to be used according to the performance of the system and to the application fields. The probes differ for the type of sensor (NTC, PTC Pt1000), type of cap, degree of protection, length of cables, field of work and mechanical dimensions.

Positive Temperature Coefficient Thermistor - PTC Thermistors are an electronic component where the resistance remains almost constant near room temperatures. However, when the temperature exceeds a constant temperature, the resistance suddenly increases.
5 Feb 2012 What are PTC thermistors? PTC thermistor definition; Characteristics of PTC thermistors. Transition temperature (Tc); Minimum resistance (Rmin) A PTC thermistor is a thermally sensitive semiconductor resistor. A flow chart in the quality section of this book (see page) shows the individual processing
Some thermistors have a positive temperature coefficient (PTC), but they are not in The measurement range of a thermistor is dependent on the probe type, mobility, and therefore the resistance, depends on temperature (Table 9.2(c)).
As the name indicates a positive temperature coefficient, PTC thermistor has a response in which the resistance rises with increasing temperature. There are two types of PTC thermistor which have very different characteristics, one showing a linear increase, whilst the other shows a sudden change in resistance. PTC thermistor outline PTC resistance RPTC versus PTC temperature TPTC (measured at low signal voltage) Sensors Motor protection, single sensors M1100 Please read Cautions and warnings and Page 5 of 12 Important notes at the end of this document.

The name was derived from the words, thermally sensitive resistor. These devices may be either positive temperature coefficient (PTC) or negative temperature

A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. PTC's are often used as resettable fuses - an increase in temperature Diameter: 3.5mm/0.13in; Length: 18in/45cm; Resistance/ Temperature table. A thermistor is a type of resistor whose resistance strongly depends on temperature. Positive temperature coefficient (PTC) thermistor:-resistance increase with increase in A graph plotted with «math xmlns=¨http://www.w3.org/ 1998 Our example thermistor performance curve chart (left) is for an NTC thermistor as we will explain below. For a positive or PTC thermistor, as temperatures Positive Temperature Coefficient (PTC) Thermistor. NTC Thermistor. In an NTC thermistor, when the temperature increases, PTC stands for „Positive Temperature Coefficient“. PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature. PTC thermistors are divided into two groups, based on the materials used, their structure and the manufacturing process.
