Shimadzu’s ServoPulser 4890 Controller has been designed for use with the most innovative testing systems. Utilizing advanced technology and superior architecture, the easy-to-use 4890 delivers outstanding performance for users at all experience levels.

Features

2-Degree-of-Freedon (DOF) PID Control
The world’s first fully digital 2-DOF PID control system enables optimum signal and noise response, and delivers maximum performance with the optimization of control parameters by the autotuning function.

Real-time Gain Adjustment
Monitoring the measurement value during testing, this function
adjusts the control in real time, ensuring accurate testing results
when there is a:

• Large change in the rigidity of test pieces from one test to another
• Substantial change in the rigidity of a test specimen during a test

Rangeless High-Resolution Measurement
A high-speed, high-resolution A/D converter enables the 4890 Controller to deliver high resolution
at any measurement scale.

Autotuning
Automatically adjusts control parameters to ensure precise measurements.

Automatic Recognition and Calibration of Sensors
Eliminates the difficult processes of adjusting rated settings and calibration and, consequently, operational mistakes and errors.

Virtual Transducer
This function performs measurements and control data produced from primary calculations
with captured data.

Mail Export Function
Check your test conditions and results remotely via e-mail with this innovative feature that saves time and improves productivity.
