SPT 90 is a generation of programmable “smart” trans-

ducers, for the measurement of all major characteristics of

an electrical system including power, energy, voltage,

current and frequency.

The SPT 90 series has a large number of functions available

to the user.

Configuration and control can be done in field, interfacing

the transducer at high levels as a remote unit.

SPT 90/SptSoft

is a software tool that

can be used to easily

down-load or upload the

programming parameters

from an SPT 90 to a PC

and from a PC to a single

SPT.

The advantages

Compared to a traditional transducer SPT 90 offers:

• TRMS measurement, that means reliable and true

measurement not affected by distortion

• Selection among many types of measurements without

changing the transducer

• Wide scaling capability solving the major field application

problems

• Combination of analogue and pulse outputs

• One integrated transducer with dual analogue output
