5 Energy Supply of SCTs
As telemetry transmitters are often placed on rotating devices, energy supply of transmitters
is a challenging task. With the D
X
telemetry system, there are several possibilities to solve
this problem:

supply by battery/rechargeable battery

inductive supply by ring stator or stator head
5.1 Power Consumption and Supply Voltage
Power consumption of the SCT is, amongst others, mainly dependent on the sensors
connected (e.g. bridge circuits). A minimal voltage of > 7,5 V is necessary to operate the
SCTs.

Power SCT (1 strain gauge) (parallel circuit of two
350Ω resistances).
