Die Taktzeit wird von der Steuerung als Istwert und mit der Maßeinheit Sekunde übertragen.

Dear native speakers, how would I say here in English?
... with second as a unit
... using second as unit
... measured in seconds
My problem with "in seconds" is that it might also be understood as "takes only a few seconds to measure/transmit" - or am I being too fussy?
