SITE-LOG LPSE-1

7-channel pulse/state/event data logger

SITE-LOG Logger The SITE-LOG LPSE-1 is 7-channel, battery powered, stand-alone, pulse/state/event data logger. The logger detects electronic or mechanical pulse counts, state changes or events in any of the seven channels and the data are saved in 4MB non-volatile flash memory for later retrieval. It works with gas/water/power meter, rain gauge, flow rate meter and any other digital signal/switch closure output devices.

Powered by configurable channel, internal pull-up and triggering edge selections, the LPSE-1 combines the functionalities of three types of loggers into one compact unit and is suitable for wide industrial applications.

Featuring an aluminum enclosure and conformal coating PCB, the SITE-LOG data logger has excellent performance in the harshest industrial environment. plug & Play USB port and versatile custom equation simplify communications and engineering unit conversion.

Simply plug the logger to computer's USB port, and the software automatically recognizes it and handles the configuration, downloading, graph viewing and more...

Features:
  • 4 megabyte memory size
  • Both USB and serial interfaces with auto baud rate of up to 115200 bps
  • Programmable input channels for pulse, state or event inputs
  • Over 5 years of battery Life
  • Powerful software for configuration, downloading, plotting, analysis and alarm reporting
  • Configurable alarm control/excitation controls
  • Wide sampling interval selections (1 second to 12 hours)
  • Rugged aluminum enclosure
  • Coated PCB to protect against moisture, corrosion and mildew.
