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
