注:“t”為感溫元件實測溫度,對于鉑電阻和銅電阻則為感溫元件實測溫度的值。 公稱壓力 一般是指在常溫下,保護管所能承受的靜態外壓而不破裂,試驗壓力一般采用公稱壓力的1.5倍。實際上,允許工作壓力不僅與保護管材料、直徑、壁厚有關,而且還與其結構形式、安裝方法、置入深度以及被測介質的流速、種類有關。 熱電偶絕緣電阻: 常溫絕緣電阻的試驗電壓為直流500V。測量常溫絕緣電阻的大氣條件為:溫度15~35℃,相對濕度45%,大氣壓力86~106Kpa。 對于長度超過1米的熱電偶,它的常溫絕緣電阻值與其長度的乘積不小于100兆歐·米, 即:Rr·L≥100MΩm L>1m 式中:Rr-熱電偶的常溫絕緣電阻值,MΩ; L-熱電偶的長度,m。 對于長度等于或不足1米的熱電偶,它的常溫絕緣電阻值應不小于100 MΩ。 熱電阻絕緣電阻: 常溫絕緣電阻的試驗電壓可取直流10~100V任意值,環境溫度應在15~35℃范圍內,相對濕度應不大于80%,常溫絕緣電阻值應不小于100 MΩ。 | WRE-130-F,WRN2-740,JB81-94,WZPK-536SA,WRE-631,WRN-624,MWFT-3,WZPK2-165SA,WZP-631,WRP2-010,WZPM-0110,WRE-624,WZP-015S,WZP-013S,WRN-625,WZPK-165S,WZP2-2312A,WRN-520,WRNM,WSSX-472,WSSX-471,WSSX-462,WSSX-461,WSSX-452,WSSX-451,WSS-572,WSS-472,WSS-571,wss-471,wss-562,wss-462雙金屬溫度計,wss-561,wss-461,wss-552,wss-452,WSS-551,wss-451,wss-582,wss-482,wss-581,wss-481,wss-512,wss-412,wss-312,wss-511,wss-411,wss-311,wss-502,WSS-402,wss-302,wss-501,wss-401,WSS-301,WSSXP-481,WSSXE-481,WSSXP-411,WSSXE-411,WSSXP-401,WSSXE-401, WZP-631單支鉑熱電阻氣源處理體AW30-02數字式聲級計,TDJ834 WRNN2-330耐腐型,耐磨型熱電偶電阻滑柱電控換向閥SR540-ES2 DW溫度變送器SBWZ-2480/24SI螺旋式拉壓測試架,HLX-J滑柱電控換向閥SR550-DM D指針式推拉力計,NK-50接近開關,LJ8A3-1-Z/AY二通防爆系列BDF-25機械閥系列,JMJ-07紅外線測溫線,ST-688S熱電偶WRP-010通用型溫度儀,TESTO 925橡膠硬度儀,LX-A數字風速計,AR846WZP-93C1套裝式熱電偶精密壓力表,YB-150WRP-130B裝配式不銹鋼接線盒熱電偶滑柱電控換向閥SR561-RS3 DW電子指零儀DMA熱電阻WZP-3312AB邵氏橡膠硬度計,LX-DG100 EG100 EG-100 MG5 MG5 MG-5 BG5 BG5 BG-5 BG012 BG012 BG-012 FGC-100HB FGC-100HB FGC100HB CNRDL100 CNRDL100 CNRDL-100 EG012 EG012 EG-012 BS1500 BS1500 BS-1500 BS400 BS400 BS-400 BS30 BS30 BS-30 HDP-5 HDP-5 HDP5 EGRS EGRS EGRS EG20 EG20 EG-20 STO-2 STO-2 STO2 SJR100 SJR100 SJR-100 BG2 BG2 BG-2 MG200 MG200 MG-200 HF-500 HF-500 HF500 EG5 EG5 EG-5 CNREA25 CNREA25 CNREA-25 BG50 BG50 BG-50 FGN-2B FGN-2B FGN2B CNRDL250 CNRDL250 CNRDL-250 HF-5 HF-5 HF5 FGJ-20 FGJ-20 FGJ20 EG200 EG200 EG-200 CNREA1KN CNREA1KN CNREA1KN SJR10 SJR10 SJR-10 FGP-2 FGP-2 FGP2 Z2S-LM-11 Z2S-LM-11 Z2SLM11 BG025 BG025 BG-025 CNRDL500 CNRDL500 CNRDL-500 HF-10 HF-10 HF-10 SDT170MD SDT170MD SDT-170MD DJ2005B DJ2005B DJ-2005B DJ2005E DJ2005E DJ-2005E DJB2005D DJB2005D DJB-2005D DJ2006C DJ2006C DJ-2006C SDT170S+ SDT170S+ SDT-170S+ DJB2005A DJB2005A DJB-2005A DJB2005C DJB2005C DJB-2005C DJB2005E DJB2005E DJB-2005E DJ2006B DJ2006B DJ-2006B X-350A X X-350AX X350A DJ2005C DJ2005C DJ-2005C DJ2005F DJ2005F DJ-2005F DJ2006A DJ2006A DJ-2006A DJ2006D DJ2006D DJ-2006D ZTB2006A ZTB2006A ZTB-2006A DJ2005D DJ2005D DJ-2005D DJ2005A DJ2005A DJ-2005A DJ2005G DJ2005G DJ-2005G DJB2005F DJB2005F DJB-2005F SDT170M+ SDT170M+ SDT-170M+ SDT170M SDT170M SDT-170M SDT170S+ SDT170S+ SDT-170S+ SDT170M+ SDT170M+ SDT-170M+ SDT170M SDT170M SDT-170M SDT170MD SDT170MD SDT-170MD ZXGC-3 ZXGC-3 ZXGC3 FH-9C FH-9C FH9C PH-200L PH-200L PH200L RM-1500 RM-1500 RM1500 CDT-2000HD CDT-2000HD CDT2000HD RM-2003B RM-2003B RM2003B RM-4A RM-4A RM4A DT-311A DT-311A DT311A HY-441b HY-441b HY441b EMT 220AL EMT220AL EMT-220AL VM-83 VM-83 VM83 VM-70B VM-70B VM70B S906 S906 S-906 DPH2005 DPH2005 DPH-2005 LC-820A LC-820A LC820A LC-830A LC-830A LC830A TOBTO2000B TOBTO2000B TOBTO-2000B S909Z-6 S909Z-6 S909Z6 PH-200LC PH-200LC PH200LC DT-5TG-1 DT-5TG-1 DT5TG1 EMT260C EMT260C EMT-260C PBX PBX PBX DT-2234B DT-2234B DT2234B TV260A TV260A TV-260A HG-8900 HG-8900 HG8900 TOBTO2000A TOBTO2000A TOBTO-2000A DPH2006 DPH2006 |
