ng>熱電阻的ng>安裝與使用ng>ng> ng>熱電阻應避免在爐旁或距加熱體太近處，應盡量安裝在震動很小的地方，同時要便於施工和維護。ng> ng>安裝位置應盡可能保持垂直，但在有流速時則必須傾斜安裝。接線盒出孔應向下方。熱電阻應按規定ng> ng>接線，一般采用三線制。連接導線應采用絕緣（最好是屏蔽）銅線，其截麵積應≥1.0平方毫米，導ng> ng>線的阻值應按顯示機表的規定配準。ng> ng>由於熱惰性會使熱電阻阻值變化滯後，為消除誤差，應盡可能地減少熱電阻保護管外徑，適應增加熱電阻的插入深度使電阻受熱部位增加。要經常檢查保護狀況，發現氧化或變形應立即措施，並定期進行校驗。ng> ng>ng>典型外形及結構尺寸（單位：mm）ng>ng> ng> ng> ng>ng>定貨需知ng>ng> ng>定貨時用戶應註明:ng> ng>產品名稱ng> ng>產品型號ng> ng>分度號ng> ng>保護管材料和直徑ng> ng>長度及插入深度Lng> ng>螺紋規格ng> ng>特殊技術要求ng> ng>ng>訂購選型ng>ng> ng>GW100、GW200ng> | ng>型溫度傳感器ng> | | | ng>－50～＋400℃ng> | ng>溫度量程（請說明溫度量程范圍）ng> | | | ng>代碼ng> | ng>材料ng> | ng>P1ng> | ng>PT100ng> | ng>P2ng> | ng>PT1000ng> | | | ng>代碼ng> | ng>連接方式（其他要求，請來電說明）ng> | ng>Z0ng> | ng>無固定裝置ng> | ng>Z1ng> | ng>活動法蘭ng> | ng>Z2ng> | ng>固定法蘭ng> | ng>Z3ng> | ng>活動螺紋（M16×1.5、M20×1.5、）ng> | ng>Z4ng> | ng>固定螺紋ng> | | | ng>代碼ng> | ng>外接保護套管直徑（其他要求，請來電說明）ng> | ng>F1ng> | ng>Φ6ng> | ng>F2ng> | ng>Φ8ng> | ng>F3ng> | ng>Φ10ng> | ng>F4ng> | ng>Φ16ng> | | | ng>代碼ng> | ng>引線方式（其他要求，請來電說明）ng> | ng>J1ng> | ng>直接引線ng> | ng>J2ng> | ng>航插引線ng> | ng>J3ng> | ng>赫斯曼引線ng> | | | ng>代碼ng> | ng>附加功能ng> | ng>Ing> | ng>本質安全型ng> | ng>Dng> | ng>隔爆型ng> | ng>MAng> | ng>礦用型ng> | ng>Eng> | ng>抗振動ng> | ng>Kng> | ng>抗沖擊ng> | ng>Lng> | ng>插入深度（請註明是否包含螺紋在內）ng> | ng>Yng> | ng>客戶要求ng> | ng>GW100、GW200ng> | ng>0～300℃ng> | ng>P1ng> | ng>Z3ng> | ng>F1ng> | ng>J1ng> | ng>MAEK50mmng> |
