使用注意事項
PT500-540 TTL數(shù)字壓力變送器使用注意事項
產(chǎn)品供電3.6VDC（范圍：3-5VDC）；
嚴禁使用硬物（如：螺絲刀、手指、鐵釘?shù)龋┤ナ沟脡盒倔w受壓力測量輸出；
電源和信號線按訂購產(chǎn)品規(guī)格要求，正確接線；
產(chǎn)品安裝時，受力部位為“過程連接六方扳手位”，扳手規(guī)格與六方相對應；
嚴禁被測系統(tǒng)的介質溫度、壓力量程、激勵電壓超過變送器的額定使用范圍；
注意保護變送器引出電纜，現(xiàn)場使用跨度過大時，建議使用金屬管保護或架空；
壓力變送器屬精密計量儀器，切勿強加沖擊、摔打，以免損壞芯體；
