GESTRA變送器LRGT系列介紹
LRGT 16-3、LRGT 16-4 和 LRGT 17-3 電導(dǎo)率變送器可用作電導(dǎo)率限制器和排污控制器，以連續(xù)測量加壓蒸汽和熱水設(shè)備中的電導(dǎo)率。它們通過 4 - 20 mA 電流輸出在參數(shù)化測量范圍內(nèi)呈現(xiàn)線性電導(dǎo)率曲線。
結(jié)合安全電子控制單元，LRGT 16-3、LRGT 16-4 和 LRGT 17-3 電導(dǎo)率變送器適用于高達(dá) SIL 2 的安全功能。
LRGT 16-3, LRGT 16-4 and LRGT 17-3 conductivity trans - mitters can be used as conductivity limiters and blowdown controllers to continually measure conductivity in pressurised steam and hot-water plants. They present a linear profile of conductivity in the parameterised measuring range via a 4 - 20 mA current output.
In combination with secure electronic control units, LRGT 16-3, LRGT 16-4 and LRGT 17-3 conductivity transmit - ters are suitable for safety functions up to SIL 2.
