‘Sci-Cal’ Computer Control Software & Interface

‘Sci-Cal’ software & hardware has been designed for use with more than 600 ‘Sci-tech’ trainers. ‘Sci-Cal’ comes in a module that can be fitted or mounted on the Sci-tech trainers very easily.

‘Sci-Cal’ box has 11 inches front HMI interactive panel, inside are i3 processor computer with it’s own hard drive & software processor with 16 to 32 analog and 16 to 32 digital signal data-loggers. The ‘LabVIEW’ processes the input signal with in-built data and formulae to tabulate results for the Sci-tech trainers.

‘Sci-Cal’ box has HDMI output for connection to a projector or an electronic whiteboard or a monitor.

‘Sci-Cal’ box has input ports for inputs from the Sci-tech trainer sensors.

‘Sci-Cal’ eliminates requirement of external computer.

Experiments
 Familiarization with the basic principle of a multi-head diaphragm pump
 Flow rate and mixing ratio depending on
o the stroke
o the stroke rate
o the counter pressure

Requirements
 Mains Input: 220 – 240V AC @ 50Hz
