SA 32 analogue data acquisition system is dedicated to measurement, monitoring and recording of analogue signals on 32 channels in 2 wires or 8 channels in 4 wires.

Designed with flexibility and precision, this system can be used in numerous applications, on site or in laboratory.

SA 32 allows 100 addresses to be programmed, which can be defined to measure real channels (up to 32 channels) or virtual channels used to perform calculations / maths functions.

Input channels are scanned by a CMOS logic circuit.

Scanning is organised in «tasks» or scanning procedures, defining what to scan (channels), how to scan (scanning start and stop, scanning rate), and how to process the results (mass storage, RS 232 output). The user has access to 16 tasks, therefore 16 different scanning subgroups.

The datalogger is completely programmable via keyboard and help menu on screen, or via RS 232 interface using LTC 32W software supplied with the unit.

Backlit LCD display shows 2 channels simultaneously either under digital or graphical format (150 points definition) on a time base adjustable between 1 s to 1 min. It also enables stored valued to be recalled on screen for display under digital or graphic format. 

SA 32 perform measurement, monitoring and recording of analogue signals coming from sensors of physical or electrical values. These signals can be:

  • Voltage: 0-10 V
  • Current: 0-20 and 4-20 mA with external shunts
  • Thermocouples: Type K/T/J/S/B/N with or without cold junction compensation
  • Resistance: 3000 Ω
  • RTD: Pt100 in 3 or 4 wires
  • Dry contacts
