裝配熱電阻
| ||
WZ系列工業(yè)用熱電阻作為溫度測量傳感器,通常與溫度變送器,調(diào)節(jié)器以及顯示儀表等配套使用,組成過程控制系統(tǒng),用以直接測量或控制各種生產(chǎn)過程中-200℃-500℃范圍內(nèi)的液體,蒸汽和氣體介質(zhì)以及固體表面的溫度。 |
| ||||||||||||
|
| ||
熱電阻是利用物質(zhì)在溫度變化時,其電阻也隨著發(fā)生變化的特征來測量溫度的。當阻值變化時,工作儀表便顯示出阻值所對應的溫度值。 |
| ||||||||||||
|
| ||
熱電阻在環(huán)境溫度為15—35℃,相對濕度不大于80%,試驗電壓為10—100V(直流)電極與外套管之間的絕緣電阻>100MΩ。 |

They serve to signal the „open/closed“ status of a fitting. This end position is communicated via two (max. six) pressure-proof enclosed limit switches with the appropriate connection and mounting elements, or by intrinsically safe initiators according to NAMUR. To ensure mechanical adaptability to the pneumatic actuators, we supply 4 consoles according to VDI/VDE 3845. The limit value transmitters as well as their components comply with the relevant EN 50014, 50018, EN 50019, EN 50028, EN 50281-1-1 and/or EN 50020 norms and have been developed, manufactured and examined in accordance with EN ISO9001. The limit value transmitters are also suitable for connecting intrinsically safe circuits.
