Process conditions
For detailed information on the process conditions and specifications, please refer to section 3.5,
“Construction details”.
When compact mounted, the process conditions can influence the operation of the transmitter if the
manufactures installation and operational conditions are not abided to.
Remote mounted transmitters are not affected by the prevailing process conditions of the sensor.
Note:
Compact-mounted transmitters are not available for all versions of sensors.
DSB data memory module
The replaceable plug and play memory module is mounted on a printed board and stores all sensor data such
as sensor constants, model numbers, serial numbers, and so on. Consequently, the memory module is linked
to the sensor and is attached to the transmitter housing with a nylon cord.
If the transmitter is replaced, the memory module should be transferred to the new transmitter. When the
flowmeter is started up, the device continues using the values stored in the memory module. Thus, the DSB
memory module provides maximum safety and comfort when device components are replaced.
Warning:
When replacing the transmitter electronics, ensure that the applicable standards
and regulations pertaining to electrical devices, device installation and process
technology are abided to. The highly integrated electronic components may be
damaged when exposed to ESD hazards. Only when installed in the transmitters
enclosure are the electronics compliant to EMC standards.
