Accsense VersaLog for Thermocouple Measurement and Alarm

Standalone Dataloggers Replace Paper Chart Recorders


For accurate standalone temperature monitoring and alarming, the Accsense VersaLog TC

Temperature Data Logger offers connection with all thermocouple types. The TC is a versatile device featuring 8 channels recording at high resolution, internal 4MB memory, and Windows configuration and analysis/plotting software. Accsense VersaLog dataloggers are a low-cost replacement for aging data acquisition devices and paper chart recorders. Their USB, Serial port and Ethernet connections make for easy local and remote access. CAS DataLoggers provides these solutions along with FREE on-call tech support—give us a call at 800-956-4437 and save!

No More Manual Measurements!

Ideal for continual temperature monitoring in life science and healthcare, the Accsense VersaLog TC logger is compact and lightweight for simple deployment. The logger’s 7 external input channels accommodate all types of external thermocouple probes, and the TC can also record ambient temperature. Additionally the unit can also function as a small voltage data logger with the input voltage range as small as -8 mV to +8 mV.

Accsense VersaLog data loggers feature a rugged, splash-resistant aluminum enclosure, and their internal electronics are protected against moisture by a PCB conformal coating.  For extended standalone operation, an internal battery is standard with the logger with a life of about 10 years.

The TC’s 16-bit analog-to-digital (ADC) converter meets most high-resolution requirements, whether monitoring temperature in medical refrigerators and freezers or for use in the lab monitoring processes and liquids. 

TC VersaLog thermocouple data loggers support a wide sampling interval range from every 20 milliseconds to every 12 hours. These data loggers record information and save measurements onto a non-volatile 4MB flash memory for quick retrieval. This amounts to up to 2 million measurements with the choice to stop or overwrite logging on a full memory.

Flexible Communications:

All VersaLog data loggers feature a built-in USB port for configuration and downloading data via PC connection. These temperature recorders offer users their choice of connection options, supporting modem or Ethernet connections with an auto baud rate of up to 115 kbps.

Alarm Outputs:

Users can configure the TC’s two programmable alarm control outputs with low or high limits to activate a relay, switch on a light, trigger an audible alarm, or signal a PLC or other device. Two configurable alarm thresholds are available per channel, and the ALARM1 A2/EXT terminal strips can be configured as alarm outputs so users can stay on top of sudden changes in their data.

The onboard LED lights red when in alarm condition, and with purchase of the inexpensive software, the VersaLog also reports its alarm status to a host PC via USB, modem or Ethernet device server.

Real-Time Software:

The intuitive Versalog SiteView software is available for configuration/setup, data download, plotting, analysis and alarm reporting.

SiteView is a Windows-based application with an intuitive graphic interface and supports USB, serial port and Ethernet connections. Fast communication speed up to 115200 bps enables quick downloads, while multiple file loading makes it easy to compare your data.
