温度传感器应该怎么选择才好呢？...

<p>看厂家资料，温度传感器好像类型很多，其中就采用的材料就有几种，有Ni1000、Pt1000、Pt100、NTC等等</p><p>我查了一下ALC的eikon，里面AI点的“Sensor Type”，无源的好像有这么多选择项：<br/>Thermistor 10KOhm with 11K Shunt 5238@77 degF<br/>Thermistor Preceon Type II 10k@77 degF<br/>Thermistor Preceon Type II 10k@25degC<br/>RTD TS-8000 Platinum -40 to 250 degF<br/>RTD TS-8000 Balco -50 to 250 degF<br/>RTD 1kOhm Nicel/Iron -50 to 250 degF<br/>RTD 1kOhm Nicel/Iron -46 to 121 degC<br/>RTD 1kOhm Platinum -46 to 121 degC<br/>RTD 1kOhm Platinum -50 to 250 degF<br/></p><p>其实一直都不知该怎么选择温度传感器的。</p>

<p>还不如让厂家给你选，你提要求，然后拿资料再看。</p>

<p>提出要求叫厂家帮你选择</p><p>一般厂家都有自己的温度传感器！</p>

<p>温度传感器的选择还要看你使用的控制器能够接受什么样的信号，是1000欧的，还是100欧的，什么电阻类型的，</p><p>而且要知道你检测的参数要求，标准的，还是精确的，一般我们做ba单纯作温度控制的话，选用标准的就可以了，如果还有湿度参数可以选温湿度一体的传感器，当然这样的传感器信号是0-10v的</p>

<p>一般常用的电阻式温度传感器就选这个型号：RTD 1kOhm Nicel/Iron -50 to 250 degC</p><p>湿度传感器就像蜘蛛说的，选用温湿度一体的传感器。</p><p>温湿度传感器常规的分两种：</p><p>一：都为0-10V输出的</p><p>二：温度L&amp;Ni1000欧姆电阻信号，湿度为0-10V电容式湿度传感器。</p>
