The new magnetostrictive Temposonicso GT ensures maximum safety for all applications where a failure will have disastrous effects on safety and cost.
* Synchronous mode - the Temposonics R-Series SSI sensor communicates position, speed and position difference measurements synchronously or asynchronously according to SSI standard.
In the synchronous mode, the measurement frequency is determined by the scanning cycle of the control system and can be as high as 3.7 kHz, depending on measurement length.
The sensor signal quality permits dynamic control with a minimum, constant delay.

Faro shows how portable CMM avoids scrap, re-work
A video shows users of manual gauging equipment that Faro gauges are just as user-friendly, but help them do their jobs faster with less scrap, re-work and labor costs.
* Asynchronous mode - dependent on application and performance data of the closed loop control system, the asynchronous mode can be used as an alternative.
In this mode, the sensor operates free-running - i e, independent of the control system's scanning cycle - while the integrated electronics circuitry employs a 'prediction-mode'.
The measurement cycles can be up to 10kHz.
Temposonics R-Series sensors permit absolute, non-contact measurement with resolution of up to one micrometer.
They operate with high accuracy and offer a repeatability < +/-0,001% FS and a linearity < 0,01% FS.
Optionally, internal linearisation permits a three to 10 times higher linearisation tolerance dependent on the measurement length.
A high electromagnetic compatibility feature protects data transfer against interference.
The sensor also resists external influences such as shock, vibration, humidity and dust.
All sensor parameters in the Temposonics R-Series SSI position sensor are factory-set, i e, after delivery, the sensor is immediately ready for connection.
If the need for subsequent readjustment of parameters (for example, resolution, output action, measuring range), software updating or sensor testing arises, this can be done on-site using a convenient PC programmer developed by MTS especially for this purpose.
This tool can be connected to the sensor and via USB interface to a Windows PC.
MTS said that the software delivered with the programmer provides clear display of all measuring signals as diagrams and offers a variety of adjustments.
Thanks to the functional extension, changing from synchronous to new asynchronous measurement, checking the temperature inside the sensor head and de-activating the internal linearization are now also possible via the programmer.
