Small probes provide voltage isolation

A HBM GmbH product story
Edited by the Engineeringtalk editorial team Jul 21, 2008

The Isobe 5600 eliminates the use of floating scopes or DAQ systems, protecting both operator and instrument, even where high voltage and EMI are involved.

The Nicolet Isobe 5600 is the third generation of optically isolated probes designed by LDS Test and Measurement.

It is smaller in size, offers better performance and has a longer battery life than its predecessors.

The isolated probe system is designed for applications that require true optical voltage isolation for safe and accurate measurements.

Successful operation of any laboratory or test cell relies on disturbance-free, accurate measurements and optical isolation is the most effective way to achieve this.

Whether it is just voltage isolation, more demanding current shunt measurements or isolation for safety reasons as in ballistics or explosive applications testing.

There are two principal ways of transmitting signals via fibre-optic links: analogue or digital.

The digital link which is incorporated into the Isobe 5600, enables measured signals to be digitised with an A-to-D convertor close to the test object, transmitted via fibre-optics, processed directly in digital form and converted back to an analogue signal with a D-to-A convertor.

Digital fibre-optic systems do not exhibit drift or noise problems and thus surpass their analogue counterparts when it comes to dynamic accuracy.

Bringing the A-to-D convertors close to the test object, however, means that the power for the A-to-D convertors must be supplied by batteries to avoid any coupling with the environment.

The Isobe 5600 eliminates the use of floating scopes or DAQ systems, protecting both operator and instrument, even where high voltage and EMI are involved.

The Isobe 5600 offers remote operation, excellent signal fidelity and elimination of ground problems.

The Isobe 5600 transmitter is heavily shielded and exclusively battery-powered.

The easily removable battery runs for a minimum of 12 hours and can be doubled to 24 hours with an optional second battery.

The Isobe 600 sender can serve up to four transmitters.

The display and rotary encoder wheel can be used to control the transmitters and to set up the amplifier range, coupling and filter in an easy and convenient way.
