Elster GmbH Gas quality measurement system EnCal 3000 The gas quality measurement system EnCal 3000 consists in its basic configuration of a measuring unit and an optional Encal3000 controller. The measuring unit is the real gas chromatograph. It performs the analysis by measuring technology auton- omously.
The concentration of each component is then measured at the end of the column by a detector. From the knowledge of the concentrations of each component, any property of the gas can be calculated. ___________________________________________________________________________________________________________ EnCal 3000 - Hardware Manual 22/02/2018 7/56...

Figure 2.10 shows the location of the cabinet heaters. fig. 2-9 Cabinet heaters location in the EnCal 3000 For the regulation of the heaters standard thermostats with a fixed setting are used. These thermostats are connected to the interconnection board close to the connectors for the power supply of the heaters (see also fig.
Helium the chance of internal damage is also reduced significantly. The purge and the small amount of helium that is vented into the housing also protects the internal components against moisture or other aggressive components entering the housing through the breather. ___________________________________________________________________________________________________________ EnCal 3000 - Hardware Manual 22/02/2018 23/56...
After the sample gas has passed the manifold it becomes split for the transport to the two analytical channels.

Local TCP/IP Data Communication The main Data Communication Port of the EnCal 3000 is the TCP/IP port, although 2 serial ModBus ports are also avail- able (see next paragraph). The TCP/IP Port (Ethernet UTP 10 Base-T) is necessary for connection with RGC 3000 (Win- dows based interface for configuration, diagnostics and report generation), but is also used by preference for ModBus communication with Flow Computers, PLC and other ModBus hosts, if they are able to handle ModBus TCP/IP.
Flow computers or another ModBus host could also be directly connected to one of the 2 serial ModBus ports internally integrated in the EnCal 3000. fig. 4-2 Typical Data Communication Set-up for TCP/IP combined with Serial ModBus Communication with the EnCal 3000 ___________________________________________________________________________________________________________ EnCal 3000 - Hardware Manual...
