美國(guó)PTC 580C I / R烤箱表面溫度計(jì)

?

I / R溫度計(jì)的設(shè)計(jì)必須正確地測(cè)量一個(gè)光源的輻射溫度。 這里通過一個(gè)著名的關(guān)于溫度計(jì)的現(xiàn)象來區(qū)分這兩類溫度計(jì)：同一個(gè)溫度計(jì)在陽光下測(cè)試得到的讀數(shù)會(huì)高于同一個(gè)溫度計(jì)在陰影中讀取同一個(gè)物體。由于太陽的能量行進(jìn)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(jì)是專為精確測(cè)量輻射和表面溫度。 

為了從不斷變化的紅外光源得到的測(cè)量，儀器必須具有快速響應(yīng)。 高風(fēng)險(xiǎn)因子和傳感元件的減少熱產(chǎn)生是這樣的設(shè)計(jì)是至關(guān)重要的。 

580型特別適于在行進(jìn)的傳送帶式爐中使用。 在一個(gè)給定的周期內(nèi)，580型會(huì)在最高溫度的地方放置它的一個(gè)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(gè)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.
