ABB UFC760BE43 3BHE004573R0043 环境温度和流体温度的一个因素
此功能包括传感器温度的监测和
流量计传感器线圈的电阻。
8.1.6.1传感器温度监测
流量计传感器中线圈的温度可以通过使用可调节的
最小/最大限值。当超过设定限值时，通过
可编程数字输出，具体取决于配置。
线圈温度是环境温度和流体温度的一个因素。测量可以，
例如可用于监测由于流体引起的超温。测量线圈温度
间接地通过线圈直流电阻（ABB专利GB 2 348 011）。
8.1.6.2传感器线圈电阻的监测
流量计传感器中的线圈可以使用可调节的最小/最大限值进行监测
线圈电阻值。当超过设定限值时，通过
可编程数字输出，具体取决于配置。
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”）。
该设备有一个内部存储器，电极的测量值沉积在存储器中
电导率被循环存储为具有可调节时间的数据记录
（1分钟…45000分钟）。最多存储12条数据记录。当第十三条记录
存储时，最旧的数据记录会被自动覆盖。
可以使用外部诊断工具将数据记录作为趋势读取或分析
（扫描主机）。
8.1.8指纹
变送器中集成的“指纹”数据库允许您比较
使用当前记录的值进行工厂校准或调试的时间。
8.1.9检查接地
此功能允许您检查设备的电气接地情况。
在检查过程中，不能进行流量测量。
使用该功能的条件：
•测量管必须完全装满。
•流量计传感器中不得出现流量。
附加安装条件：
•流量计传感器不得配备前置放大器
This function includes the monitoring of the sensor temperature and the monitoring of the
resistance of the flowmeter sensor's coils.
8.1.6.1 Sensor temperature monitoring
The temperature of the coils in the flowmeter sensor can be monitored by using adjustable
minimum/maximum limit values. When a set limit value is exceeded, an alarm is tripped via the
programmable digital output, depending on the configuration.
The coil temperature is a factor of the ambient and fluid temperatures. The measurement can,
e.g., be used to monitor overtemperature due to the fluid. The coil temperature is measured
indirectly via the coil DC resistance (ABB patent GB 2 348 011).
8.1.6.2 Monitoring of the sensor coil resistance
The coils in the flowmeter sensor can be monitored by using adjustable minimum/maximum limit
values for the coil resistance. When a set limit value is exceeded, an alarm is tripped via the
programmable digital output, depending on the configuration.
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 device has an internal memory where the measured value for the electrode deposits and
the conductivity are cyclically stored as a data record with an adjustable time
(1 min ... 45000 min). A maximum of 12 data records is stored. When the thirteenth record is
stored, the oldest data record is overwritten automatically.
The data records can be read out or analyzed as a trend using the external diagnostic tool
(ScanMaster).
8.1.8 Fingerprint
The “fingerprint” database integrated in the transmitter allows you to compare the values at the
time of factory calibration or commissioning with the currently recorded values.
8.1.9 Checking the grounding
This function allows you to check the electrical grounding of the device.
While the check is in progress, no flow measurement can take place.
Conditions for using the function:
• The measuring tube must be completely full.
• No flow must be occur in the flowmeter sensor.
Additional installation conditions:
• The flowmeter sensor must not be provided with a preamp
