The various possible configuration levels for a pressure measurement solution aren’t defined conceptually in any standard. At WIKA we’ve chosen the next terminology:
Pressure sensor (Pressure transmitter)
Pressure sensor (pressure transmitter)
A pressure sensor (also pressure transmitter) delivers a standardised, processed signal inside a housing with commonly available pressure connection and electrical connection. Typically, it might be coded and ordered as a catalogue product and therefore supplies the customer with a plug-and-play solution. Nevertheless, customised versions are possible when supported with a corresponding ?business case?.
Pressure sensor module
Pressure sensor module
A pressure sensor module is made for OEM applications. It delivers a standardised and calibrated signal, but could be customised pertaining to connections and size. EMC precautionary measures must be arranged in the customer application.
Sensor elements and their assemblies
Sensor elements and their assemblies
Sensor elements and their assemblies deliver an uncalibrated signal in mV/V and will be designed to suit the client through corresponding modifications of the pressure connection or addition of an incident etc. Here the client is responsible for the calibration and therefore for the accuracy achieved.
A tabular comparison summarises the options for pressure sensors:

As is shown in the table, specific sensor modules and assemblies with sensor elements require an intensive coordination between your customer and the sensor supplier. In order to find the perfect solution, a joint ?value innovation workshop? can offer a good solution.
