Thermo Fisher Scientific  has launched the Temposonics S-Series ServoSensor from MTS.

The device eliminates costly and complex PLC setups used for set-point control.

The ServoSensor is a complete servo controller installed and interfaced inside an MTS Temposonics S Series sensor.

The ServoSensor capitalises on smaller, more powerful microprocessors and advances in surface-mount technology to eliminate the need for an external controller.

The design also decreases control cabinet panel space, reduces mounting hardware and runs on a single 24Vdc power supply. As a result, ServoSensors are well suited for many applications that require high accuracy and fast response.

The ServoSensor handles position and error information efficiently by integrating MTS Temposonics sensing algorithms directly into the sensor.

Processing of data is accomplished in the sensor head and the ServoSensor typically mounts inside an actuator with a short drive cable (one foot or less) running from the sensor to servo value.

ServoSensors store PID and operational software and are programmed with PCs or PLCs via RS485 communication. The user defines servo-loop dynamics, including gains and zero adjustments, as well as operating parameters such as velocity, acceleration, dwell time, travel limits, sensor resolution and emergency stops.

The improvements allow Temposonics S Series ServoSensors to close the loop in 1ms or less. Conventional systems have typical response times of 2ms.

ServoSensors have run successfully with servo loop times of 500ms at resolutions of 0.0005 inches.

Features include:

* Self-contained servo controller in sensor head

* High speed loop closure down to 500ms

* High resolution and linearity

* Proven reliability and ruggedness

* Four selectable modes of operation - up to 29 units per link

* Rod and profile style application housings

* Two wire RS-485 network compatible

* Visual indications of power and status

* Two-year warranty

* CE certified.
