Checklist for Product Assessment

You can check here whether a product corresponds to your requirements:

The illustration shows:
above - sensoring (process interface)
below - PC connection (data interface)

Overview in groups:
- Process interfaces
- Data interfaces
- Integrated functions
- Data security
- Construction size, climate protection

Use the table below to determine which criteria are important for your application.
You can then check whether a product matches your requirements.

Process interfaces	Essential	Optional	Unimportant
Signal conditioning. No extra requirement for measuring transducers when connecting sensors.
Potential isolation. No requirement for extra amplifiers.
Analog output in physical units (bar, °C, Litre/min etc.)
Calibration of sensors
Measurement accuracy and resolution
Measurement rate
Extendable system
Low cabling costs; Modular devices; Location near signal source
Detachable clamps (cost factor when installing/deinstalling devices)

Data interfaces, PC connection	Essential	Optional	Unimportant
Network capability, (Ethernet, TCP/IP protocol)
Data transmission in existing network (Intranet)
Utilization of existing PCs
Modem link for data transfer (data storage access, alarms)
Standard plug connectors, standard cabling
Extra interface (RS232) for connecting measurement equipment such as scales, analysis equipment etc.

Integrated functions	Essential	Optional	Unimportant
Control functions (PLC programming)
Regulator functions
Limit values
Calculation channels
Configurable process controls
Protocol and interface (RS232) for connecting scales, analysis equipment, large displays etc.
Automatic malfunctioning notification to PCs
Password control

Data security	Essential	Optional	Unimportant
Integrated functions capable of running independently from external PCs and networks (i.e. data protected from unreliable external devices)
Measurement data, historical data and data for process analysis to be stored in devices, (i.e. protection against data loss in the event of external PC/network failure)

Construction size, climate protection	Essential	Optional	Unimportant
Built-in or table-top design
Construction size
Temperature
Protection type
