ABB UFC760BE1142 前部和后部安装接地板
通过使用可调节的最小/最大极限值来监测流体的电导率。
当数值低于或超过设定限值时，通过
可编程数字输出，具体取决于配置。
使用该功能的条件：
•该功能适用于公称直径范围2）DN 10…300（3/8“…12”）。
•外部变送器的信号电缆长度不得超过
50米（164英尺）。
•对于该功能，流体的电导率必须在
20μS/cm。。。20000μS/cm。
附加安装条件：
•使用塑料管时，在设备的前部和后部安装接地板。
•测量电极上不得有任何沉积物。
1） 目前，该功能仅适用于没有防爆或有防爆功能的设备
2区/2区。对于1区/1区的设备，该功能正在准备中（该功能已实施
在软件中，但不能用于分区1/Div.1中的设备）。
2） 指定的标称直径范围仅对ProcessMaster有效。有效的标称直径范围
卫生硕士是DN 10…100（3/8“…4”）。
通过使用最小值/最大值来监测电极和接地之间的阻抗
极限值。这使得发射器能够检测到电极精细短路或泄漏。

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.
