6.2 System configuration
Transmitter:
The CT transmitter regulates the excitation of the sensor vibration system and processes the sensor sig-
nals. The standard model is equipped with two analog 0/4 to 20 mA outputs, an impulse or frequency
output and a status output, and is enabled for digital data transfer via the HART
® protocol. The device is
also available with a Profibus-PA field bus.
Sensor:
The CMM, CMB and CMU sensors measure flow, density and temperature in fluids. The device can be
used to perform measurements with any liquid or gaseous product providing that the sensor material is
suitable for the product being used.
6.2.1 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 mod-
ule 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.
