+GF+signet 3-2540/3-2517流量傳感器的比較和選擇

2540高性能流量傳感器
2540型葉輪式流量傳感器采用了不銹鋼材質(zhì)，因此具有很好的強(qiáng)度和耐腐蝕性。的內(nèi)部回路結(jié)構(gòu)使它在測(cè)量過(guò)程中無(wú)需放置磁體，因此也具有了很高的靈敏度。它的測(cè)量范圍為：0.1-6m/s.FluoroloyB /PTFE材質(zhì)的軸承和鎢碳合金的軸提供了相當(dāng)高的耐磨性能。2540型傳感器提供現(xiàn)場(chǎng)可更換的電子單元，并有突變電壓抑制器（TVS），對(duì)大電壓（如雷電）引起的現(xiàn)場(chǎng)線路的沖擊干擾，具有很強(qiáng)的抗擾性能。

·能夠兼容的Signet變送器：8550，8900，5600
·適用的領(lǐng)域：流速較低，或其工作壓力較高，不適用于純水

相對(duì)3-2517,2540線圈不帶磁性,如用戶管道中如有細(xì)小鐵屑等,不會(huì)吸附在轉(zhuǎn)子上.造成測(cè)量的偏差.

2517銅質(zhì)葉輪流量傳感器

　　 2517型葉輪式流量傳感器采用了增強(qiáng)的堅(jiān)固的銅質(zhì)結(jié)構(gòu)，適用于多種應(yīng)用情況。它具有較寬的流量范圍：0.5-6m/s。能測(cè)量滿管流量和適用低壓系統(tǒng)。FluoroloyB/PTFE材質(zhì)的軸承和鎢碳合金的軸提供了相當(dāng)高的耐磨性能。2517型銅質(zhì)傳感器，在與8150電池供電的累加器結(jié)合時(shí)，傳感器的流量信號(hào)可實(shí)現(xiàn)遠(yuǎn)程累加。傳感器適用的安裝管徑為：DN40-DN600。采用1.5in.（或ISO7/1-R1.5）螺紋的過(guò)程接頭。2540傳感器可提供帶排放閥的Hot-Tap結(jié)構(gòu)，可實(shí)現(xiàn)不關(guān)閉過(guò)程管道進(jìn)行裝卸，管徑上限為DN900。

選型
3-2517.100 訂貨號(hào) 198840003 接頭類型:1.5 inch NPT
3-2517.101 訂貨號(hào) 198840007 接頭類型:1.5 inch ISO

相對(duì)3-2540,2517線圈帶磁性,如配合3-8550使用,則可以不需要附件電源.更加方便.如水中無(wú)金屬雜質(zhì),則適合使用+GF+signet 3-2517的流量傳感器.

3-2540系列詳細(xì)英文介紹

2540 Stainless Steel High Performance Flow Sensor

The Signet 2540 Paddlewheel flow sensor offers the strength and corrosion resistance of stainless steel for liquid applications with low velocity measurements. Unique internal circuitry eliminates the need for magnets in the process fluid, enabling flow measurement of 0.1 to 6 m/s (0.3 to 20 ft/s) while maintaining the advantages of insertion sensor design. Rulon® B (Fluoroloy B®/PTFE) bearings and Tungsten Carbide pin provide exceptional wear resistance.

The Signet 2540 offers field replaceable electronics and transient voltage suppression (TVS) to provide greater immunity to large voltage disturbances (i.e. lightning) sometimes encountered in field wiring. Sensors can be installed in DN40 to DN600 (1½ to 24 in.) pipes using the 1½ inch NPT or ISO 7/1-R 1.5 threaded process connection. The sensors are also offered in a hot-tap configuration with a bleed valve service without process shutdown in pipes up to DN900 (36 in.). Both styles of sensors must be used in full pipes and can be used in low pressure systems.
