A hardware unit built into a waterproof housing:
EM4214 consists of a hardware unit built into a waterproof housing. The EMA transducer is connected to the unit. The scope of supply may include various EMA transducers including ones operating with a gap up to 6 mm, high temperature EMA transducers, as well as pulsed electromagnet transducers.
For integration into external systems, a developer manual and an exchange protocol are provided.
