美國PTC 580FM 帶有磁鐵與鋼板彈簧的I / R烤箱表面溫度計

?

I / R溫度計的設計必須正確地測量一個光源的輻射溫度。 這里通過一個著名的關(guān)于溫度計的現(xiàn)象來區(qū)分這兩類溫度計：同一個溫度計在陽光下測試得到的讀數(shù)會高于同一個溫度計在陰影中讀取同一個物體。由于太陽的能量行進通過相同的空氣，空氣的溫度可以比輻射溫度要少得多。 PTC°的580型I/R烤爐溫度計是專為精確測量輻射和表面溫度。 

為了從不斷變化的紅外光源得到的測量，儀器必須具有快速響應。 高風險因子和傳感元件的減少熱產(chǎn)生是這樣的設計是至關(guān)重要的。 

580型特別適于在行進的傳送帶式爐中使用。 在一個給定的周期內(nèi)，580型會在最高溫度的地方放置它的一個指針。 一種磁性組件，保持最大的指針固定，這樣溫度的讀數(shù)可以在一個加熱循環(huán)結(jié)束后被讀取。

I/R thermometers must be designed to correctly measure the radiation temperature of a source. The well known phenomena of a thermometer in the sun reading a higher temperature than the same thermometer in the shade are examples of how the two types of thermometers must differ. The air temperature can be much less than the radiation temperature, yet the sun's energy travels through the same air. PTC°'s Model 580 IR Oven Thermometer is designed for accurately measuring both radiation and surface temperatures. 

In order to obtain measurements from changing IR sources, the instrument must have a fast response. A high exposure factor and reduced thermal mass of the sensing element are critical to this design. 

The Model 580 is particularly adapted for use in traveling belt type ovens. The 580 positions an ancillary hand at the highest temperature for a given cycle. A magnetic assembly holds the max hand securely so that the temperature can be read at the end of a heating cycle.
