Dx-lähetinyksikkö (SCT)
Pieni 14g painava Dx-lähetinyksikkö sisältää etuasteen ja digitalisoinnin kuudelle mittauskanavalle sekä lähettimen ja integroidun antennin.
One telemetry for various signals
Gone are the times in which a separate transmitter unit is needed for each sensor type. The Dx transmitter unit has universal signal conditioning that supports different types of sensors.
Laaja käyttölämpötila-alue
Kylmässä ja kuumassa, laajalla lämpötila-alueella Dx-lähetinyksikkö toimii luotettavasti.
Vakiomallina -40 °C .. +85 °C laajennetulla toiminta-alueella -40 °C .. +125 °C.
