美國KIMRAY監(jiān)測器基本分類專業(yè)的為大家介紹下，當(dāng)火焰監(jiān)測器準(zhǔn)備燃燒時。會出來三種火焰的，不同的三咱顏色分類的。這個就根據(jù)火的溫度來的。出現(xiàn)的的顏色分別為單紫外、單紅外、雙紅外。然而出現(xiàn)這個問題的時候，各位用戶就要注意下的。時刻觀查火焰出現(xiàn)的火氣的。像KIMRAY品牌的話我們直接走貨我們美國公司的，一手的好貨源，一手的好價格及的服務(wù)的。歡迎各位廣大用戶真誠的或者是來公司面談都是OK的。<BR>美國凱姆瑞根據(jù)火焰的光特性，目前使用的火焰探測器有三種：<BR>對火焰中波長較短的紫外光輻射敏感的紫外探測器；對火焰中波長較長的紅外光輻射敏感的紅外探測器；同時探測火焰中波長較短的紫外線和波長較長的紅外線的紫外/紅外混合探測器。<BR>具體根據(jù)探測波段可分為：單紫外、單紅外、雙紅外、三重紅外、紅外\紫外、附加視頻等火焰探測器；<BR>根據(jù)防爆類型可分為：隔爆型、本安型；光譜遠紅外火焰?zhèn)鞲衅髂軌蛱綔y到波長在700納米～1000納米范圍內(nèi)的紅外光，探測角度為60，其中紅外光波長在880納米附近時，其靈敏度達到zui大。遠紅外火焰探頭將外界紅外光的強弱變化轉(zhuǎn)化為電流的變化，通過A/D轉(zhuǎn)換器反映為0～255范圍內(nèi)數(shù)值的變化。外界紅外光越強，數(shù)值越??；紅外光越弱，數(shù)值越 。 美國KIMRAY火焰監(jiān)測器基本分類是什么
KIMRAY火焰監(jiān)測器HT-18PG資料下載ACTION:Direct action; Pilot Output Pressure (Yellow) increases with temperature rise. As long as the temperature is above the set
point, the output will remain at supply pressure. If the pilot flamegoes out, the pressure decreases and drops to zero.
APPLICATIONS:
Used as a Pilot safety shutdown or as a high stack temperature shutdown.
TEMPERATURE RANGE:
-30°F minimum to 2100°F maximum
-34°C minimum to 1149°C maximum
SUPPLY PRESSURE:
5 psig minimum to 30 psig maximum.
OPERATION:This Thermostat consists of a STAINLESS TUBE for monitoring the pilot flame, which is connected by a Low Expansion Alloy Rod to a BELLOWS ASSEMBLY. The changes in the length of the STAINLESS TUBE operate a PILOT PLUG seat. The PILOT PLUG consists of two stainless balls rigidly connected together. The seat at BALL 1 is the Output Pressure vent (Yellow to Atmosphere). The seat at BALL 2 is the Supply Pressure inlet (Violet to Yellow).
Assume the set point on the HT 12PG is above the temperature of the system. The vent at BALL 1 is open and the inlet at
BALL 2 is closed. Output Pressure (Yellow) is at 0 psig or vented.
As the temperature rises in the system, the STAINLESS TUBE or outer tube increases in length to move the Thermostat Bellows Assembly in a direction to first close the seat at BALL 1 (Yellow to Atmosphere) and open the seat at Ball 2 (Violet to Yellow). Output Pressure (Yellow) increases, opening a safety valve which was blocking gas supply for the burner and pilot light system.
