SPG data acquisition system

Description

SPG computer measurement system:

This interface was primarily built for temperature measurements with thermocouples. It can also be used with a wide range of other devices, since the input range is programmable.

Many of our sensors can be adapted to the SPG with an external power supply.

The interface has 16 inputs, with one of them dedicated to the internal temperature of the connectors, for thermocouples' calibrations. One of them can also be used to do an auto-zero function.

The interface also has 4 digital inputs and 4 open collector outputs.

Visual Basic (v3.0) source code is available on request for developers.

Technical specifications

SPG interface:

16 voltage inputs    balle_verte.gif (257 bytes) 12 bits analog to digital converter
Range    balle_verte.gif (257 bytes) ± 5 volts or ± 10 volts
Gain    balle_verte.gif (257 bytes) Programmable gain of 1,2,4,8,16,32,64,128
Junction    balle_verte.gif (257 bytes) Cold junction temperature
Other I / O    balle_verte.gif (257 bytes) 4 TTL inputs
   balle_verte.gif (257 bytes) 4 open collector outputs, 250 mA max.
Data connection    balle_verte.gif (257 bytes) Printer port connections on any PC

SPG software:

The interface is sold with a Windows program, controlling the interface. Graphs can be plotted in real time, outputs can be associated with inputs for control feedback. All thermocouples are already calibrated in software.

System requirements:

Any windows system with printer port.
