NTC THERMISTIR SENSORS · 热敏电阻温度传感器

LINGEE

热敏电阻(Thermistor)是对热敏感的半导体电阻(Thermal Sensitive Resistor)，其阻值随温度变化而发生非常显著变化的半导体。一般而言分为两大类。一类是电阻值随温度升高而升高的 PTC（ Postive Temperature Coefficient）热敏电阻。另一类是电阻值随温度升高而降低的 NTC （Negative Temperature Coefficient）热敏电阻。本目录说明仅限于NTC 热敏电阻。

A thermistor is "a thermally sensitive resistor" that is a semiconductor whose resistance varies significantly with

temperature. In general, there are two types thermal senstive resistor. One is PTC ( Postive Temperature Coefficient);

the resistance increases as temperature increases. The other is NTC (Negative Temperature Coefficient); the

resistance decreases as temperature increases. The following description is applicable only to NTC thermistors.

热敏电阻是应用于信息系统与控制系统的敏感元件，主要用于对温度的测量、控制、保护及用作加热器。热敏电阻是一种由锰、铜、硅、钴、镍、铁、锌等多种金属氧化物为原料烧结而成的陶瓷半导体感热晶体。使用温度在-50～+1000℃之间，涵盖了日常温度控制所需的温度范围。热敏电阻体积小、稳定性好且响应性高，在国防、工控、通信、汽车、航天等领域以及日常家电中得到了广泛的应用。

NTC thermistor is an sensitive elements widely used in information system and control system, which is mainly used

for temperature measurements, control, protection and heating. Thermistors are thermally sensitive elements of

sintered fine ceramic semiconductor composed of several transition metal oxides, primarily Mn, Co and Ni. Their

operating temperature range is from -50°C to +1000°C that covers the whole range necessary for ordinary

temperature control. They are also small, stable and have great sensitivity. Thanks to these features, they are used in

large quantities as temperature sensors and temperature compensation elements in consumer electronic appliances

and industrial equipment.

Four Important Parameters [四个重要的参数]

热敏电阻的性能主要以电阻值、B值、热耗散常数δ、热时间常数τ这4个参数来表示。有时也用电阻温度系数α作为辅助常数。

Basically, characteristics of a thermistor is represented by four constants: resistance R, B constant, thermal

dissipation constant δ and thermal time constant τ. And Temperature Coefficient of Resistance α is listed in some

application.

R · Resistance [电阻值]

热敏电阻的电阻值R和绝对温度T之间，有以下近似关系。

Between resistance R and absolute temperature T, there is the following approximate relationship.

R1 = R2 expB(

……………………… (1)

根据公式、可以求证任意温度T时的热敏电阻R。

Thermistor resistance R at any temperature T can be calculated from equation (1).

R1: Resistance (Ω) at absolute temperature T1 (K) 绝对温度T1 (K) 时的电阻值

R2: Resistance (Ω) at absolute temperature T2 (K) 绝对温度T2 (K) 时的电阻值

B : B constant B值

B · B constant [B值]

B值是电阻在2个温度之间的电阻值变化量的常数，由以下计算公式得出。

B is a constant that expresses a change rate in resistance between two temperatures, which is derived from the

equation (1).

B值一般是B25℃/50℃=2000～6000K，B值越大每1℃的电阻变化率也变大。

In general, B constant value ranges B25°C/50°C = 2,000 - 6,000K. The higher the B value is, the greater the change

rate in resistance per 1°C becomes.

δ · Thermal dissipation constant [耗散常数]

LINGEE

耗散常数δ是指给热敏电阻通电加热时，热敏电阻晶体表面和引线产生自热的热量大小程度。耗散常数δ可以用公式(3)计算出附加在热敏电阻上的消耗与相应的温度上升值。

Thermal dissipation constant δ is a constant that expresses a degree of radiation from surface and lead wires of a

thermistor element, when electric current is applied to heat it up. Thermal dissipation constant δ can be determined by

the equation (3) as a ratio between a power consumption applied to a thermistor and a degree of temperature

increased by the power.

进行精密温度测量或者控制时，要观察热敏电阻的耗散常数δ的值，控制电流，避免通过热敏电阻的电流过大电阻本身加热而引起的温度误差。此产品介绍中所述耗散常数是指在静止空气中的单个热敏电阻晶体的值。请注意在组装加工成温度传感器之后其δ的値会有变化。

In order to measure temperature accurately and to control precicely, it is important to look closely at the value of of a

thermistor and minimize electric current so that measurement error caused by heating is eliminated. Thermal

dissipation constant in this catalog shows a value when a discrete element is placed in still air. Please note that values

for assembled thermal sensors will be different.

τ · Thermal time constant constant [热时间常数 sec.]

热时间常数τ是在热敏电阻的周围温度或通过热敏电阻的电流在发生激烈变化的情况下，其电阻值发生急变的时间程度的常数。热时间常数是热敏电阻晶体的温度从初始值到最终值的温度差(1-1/e)，即到达63.2％时所需要的时间。

Thermal time constant T is a constant which indicates how fast resistance of a thermistor follows to a change in

surrounding temperature or electric current injected. The constant is expressed by a time to reach to (1-1/e) or 63.2%

of a difference between initial and final achieving temperatures of a thermistor element.

T =（ T2-T1）（ 1-exp（-t /τ）) + T1

T =（ T2-T1）（ 1-e-1） + T1

DESCRIPTION

The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over an one-wire bus that by definition requires only one data line

(and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need

for an external power supply.

Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same one-wire bus. Thus, it is simple to use

one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC envi-ronmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
