General Properties of U-Touch PRO Control Units

U-Touch PRO Control Units with integrated TFT-LCD human machine interface, have been designed with 4 channels for acquisition and processing of data obtained by sensors that produce voltage or current such as load cells, pressure or displacement transducers and also calculation of test results from this data and presentation of test results to users in desired format All the operations are controlled by touch screen display. (Depending on the application type, a number of channels will be configured. Channel names and units can be defined by the user.

The U-Touch PRO Control Units can be set up to perform load controlled tests or displacement controlled tests only by pushing buttons. That means the unit can control the machines for

Bituminous mixtures / Asphalt tests such as Marshall stability, indirect tensile,
Concrete and cement mortar tests such as compressive, flexural and splitting tensile
Soil tests such as uniaxial, triaxial, direct shear, cbr, consoladation
Steel products tests such as yield, tension, elongation and so on

U-Touch PRO Conrtol Units enable simultaneously display machine status, test values, warnings during operation and test graphs such as load-time or load-displacement curves in real time.

U-Touch PRO Control Units provide accurate and precise testing by means of P.I.D. control.U-Touch Pro provides users a specimen-specific autotuning option to determine the PID control parameters. Every analog data channel can be calibrated and digital gain parameters can be defined independently. Specific P.I.D. coefficients can be defined automatically for different samples using U-Touch Pro.

The Control Units integrate a user-friendly interface that shows all the necessary menu options as buttons and tabs. Sample information, test information, test parameters and user information can be modified and saved for later use by operators and input into the HMI for better visualization and storage of test results.

U-Touch PRO Control Units display of necessary warnings and current state of testing instantly on the touchscreen.

A thermal printer can be integrated to U-Touch PRO Control Unit and test results can be printed without the necessity for a personal computer.

U-Touch PRO can be used to retrofit old model equipment to have advanced data acquisition and process electronic.The Units can be also used as a data acquisition unit on any exsisting machine.

Main Features:

4 analog channels for load cell or pressure sensors or displacement sensors.
