Ptc thermistor chart
2 Nov 2009 A PTC thermistor can have a resistance of 10,000 ohm at 77° and then a of a temperature vs. resistance chart of one type of NTC thermistor.) Our temperature sensor probes can be integrated with any of our PID temperature These devices may be either positive temperature coefficient (PTC ) or versus temperature curve and are interchangeable from one Thermistor to another 8 May 2008 Table 7. Ambient temperature, corresponding resistance, temperature coefficient and maximum expected temperature error for KTY84/130 and 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.

When PTC thermistors are encapsulated with sealing material, the precautions given in chapter "Mounting instructions", "Sealing and potting" must be observed. When the thermistor is mounted, there must not be any foreign body between the electrode of the thermistor and the clamping contact. In PTC thermistors, the resistance increases as temperature increases and conversely with NTC thermistors the resistance decreases as temperature increases. NTC thermistors are designed to be most sensitive to temperature changes in the lower (colder) end of the range. They are most commonly used to sense temperature. 8 - 10,000 ohm NTC thermistor (Carel) 10 - 3,000 ohm NTC thermistor 12 - 10,000 ohm NTC thermistor (Type II) 13 - 5,000 ohm NTC thermistor 14 - 1,035 ohm Silicon PTC 15 - 100,000 ohm NTC thermistor 16 - 10,000 ohm NTC thermistor (Eliwell) 17- 20,000 ohm NTC thermistor 18- 2,252 ohm NTC thermistor 21 - 1,800 ohm NTC thermistor Your first stop for NEMA and Metric motor repair & service PTC thermistors act as thermal protection for electrical machines, and are well known particularly as motor-protectors.They are available with or without insulating sleeve and have flexible connecting leads. PTC thermistors have a non-linear resistance/temperature response, and at a specified temperature the resistance changes rapidly to a very As can be seen be the graph, the resistance of the thermistor drops very quickly. In the typical control range (0°C to 40°C), 10K thermistors offer good sensitivity to changes in temperature, and this is the range in which most 10K thermistors are typically used. 10K thermistors can be used at much higher temperatures, but will suffer poorer

The minimum resistance of the PTC device is the lowest value of the R-T curve that the thermistor can achieve. It is the point just below the transition temperature The resistance versus temperature graph shows how a. PTC reacts to temperature changes. Tb = transition temperature. The temperature where the ceramic 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 Limit temperature monitoring. Features. Thermistor pellet with insulating encapsulation.

PTC thermistors Screw-fixing type for overheat sensing, PTFL series PTC thermistors have a non-linear resistance/temperature response. This will have the same effect as a break in the circuit or a failure of the thermistor. The PTC's resistance values for motor protection are specified in DIN 44081/44082.
