ABB UFC760BE1142 前部和后部安裝接地板
通過使用可調(diào)節(jié)的最小/最大極限值來監(jiān)測(cè)流體的電導(dǎo)率。
當(dāng)數(shù)值低于或超過設(shè)定限值時(shí)，通過
可編程數(shù)字輸出，具體取決于配置。
使用該功能的條件：
?該功能適用于公稱直徑范圍2）DN 10…300（3/8“…12”）。
?外部變送器的信號(hào)電纜長(zhǎng)度不得超過
50米（164英尺）。
?對(duì)于該功能，流體的電導(dǎo)率必須在
20μS/cm。。。20000μS/cm。
附加安裝條件：
?使用塑料管時(shí)，在設(shè)備的前部和后部安裝接地板。
?測(cè)量電極上不得有任何沉積物。
1） 目前，該功能僅適用于沒有防爆或有防爆功能的設(shè)備
2區(qū)/2區(qū)。對(duì)于1區(qū)/1區(qū)的設(shè)備，該功能正在準(zhǔn)備中（該功能已實(shí)施
在軟件中，但不能用于分區(qū)1/Div.1中的設(shè)備）。
2） 指定的標(biāo)稱直徑范圍僅對(duì)ProcessMaster有效。有效的標(biāo)稱直徑范圍
衛(wèi)生碩士是DN 10…100（3/8“…4”）。
通過使用最小值/最大值來監(jiān)測(cè)電極和接地之間的阻抗
極限值。這使得發(fā)射器能夠檢測(cè)到電極精細(xì)短路或泄漏。
當(dāng)數(shù)值低于或超過設(shè)定限值時(shí)，通過

電導(dǎo)率變化。
The conductivity of the fluid is monitored by using an adjustable minimum/maximum limit value.?
When the value falls below or exceeds the set limit value, an alarm is tripped via the?
programmable digital output, depending on the configuration.?
Conditions for using the function:?
? This function is available in the nominal diameter range 2) of DN 10 … 300 (3/8 “ ... 12 “).?
? The signal cable length of the external transmitter must not exceed a maximum value of?
50 m (164 ft) .?
? For this function, the conductivity of the fluid must be in the range?
20 μS/cm ... 20,000 μS/cm.?
Additional installation conditions:?
? When using plastic tubes, install a grounding plate at the front and back of the device.?
? There must not be any deposits on the measuring electrodes.?
1) At present, the function is only available for devices without explosion protection or with explosion protection for?
Zone 2 / Div. 2. For devices in Zone 1 / Div. 1 this function is under preparation (the function is already implemented?
in the software, but cannot be used for devices in Zone 1 / Div. 1).?
2) The specified nominal diameter range is valid for ProcessMaster, only. The nominal diameter range valid for?
HygienicMaster is DN 10 … 100 (3/8 “ ... 4 “).
The impedance between the electrode and ground is monitored by using a minimum/maximum?
limit value. This enables the transmitter to detect an electrode fine short or leakage.?
When the value falls below or exceeds the set limit value, an alarm is tripped via the?
programmable digital output, depending on the configuration.?
Conditions for using the function:?
? This function is available in the nominal diameter range 2) of DN 10 … 300 (3/8 “ ... 12 “).?
? The signal cable length of the external transmitter must not exceed a maximum value of?
50 m (164 ft) .?
? For this function, the conductivity of the fluid must be in the range?
20 μS/cm ... 20,000 μS/cm.?
Additional installation conditions:?
? When using plastic tubes, install a grounding plate at the front and back of the device.?
? There must not be any deposits on the measuring electrodes.?
? The measuring tube must always be completely full, and the fluid must feature only minor?
conductivity variations.
