Imagination for a pressure measurement solution aren’t defined conceptually in any standard. At WIKA we have chosen the following 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 really is coded and ordered as a catalogue product and thus supplies the customer with a plug-and-play solution. Nevertheless, customised versions are possible when backed up with a corresponding ?business case?.
Pressure sensor module
Pressure sensor module
A pressure sensor module is designed for OEM applications. It delivers a standardised and calibrated signal, but can be customised pertaining to connections and size. EMC precautionary measures should 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 Extra is in charge of 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 a rigorous coordination between your customer and the sensor supplier. And discover the best possible solution, a joint ?value innovation workshop? can provide a good solution.
