Site-Log 4 Channel RTD Datalogger

Site-Log 4 Channel RTD Datalogger

The SITE-LOG LRTD is a 4-channel, battery powered, standalone PT100 RTD data logger. The logger records the ambient temperature and four resistance temperature detectors (RTDs). Data is stored in 8MB non-volatile flash memory for later retrieval. Different models are available for PT500 and PT1000 sensor probes.

Its versatile equations simplify engineering unit conversion. Plug & Play USB port makes the communication easy and Its aluminum enclosure makes it excellent in the harshest industrial environment.

16-bit ADC makes it well suited for science and laboratory applications where precise and accurate measurements are critical.

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

Alarm Switch
The Site-Log data logger also provides alarm outputs controlled by the low and high programmable alarm thresholds of each enabled channel. The alarm control outputs can be used to turn on/off external alarm devices such as strobe lights, sirens or alarm telephone diallers..

Sensor Excitation Control
The Site-Log data logger also has an excitation control output used to switch the power supply of the external transducer/transmitter, so that these are only powered during a reading, saving on transducer battery consumption...
