Pressure transmitter NAE 8256

The NAE 8256 features the extremely robust and stable thin-film-on-steel sensor element that is well proven and known for it’s long-term stability. NAE 8256 share it’s compact housing with the other pressure transmitters in the NAx-series making NAE one of the smallest pressure transmitters of its kind with ship approvals.

The NAE 8256 was upgraded in 2021 and now also features switching outputs with 1 or 2 PNP outputs as option. The switching outputs can be configured from factory with custom switch point, reset point and delay setting as well as NO or NC settings. Parametrization can also be done with an SMI Sensor Master Interface together with a smartphone app (Android).

The new NAE also has a wider pressure range starting at 0…0.2 up to 0…700 bar and a DNV EU RO Mutual Recognition Type Approval Certificate.
