LPTH-1 Site-Log Thermistor Datalogger
Description
The Site-Log LPTH-1 is an 7-channel, battery powered, stand alone thermistor data logger. The logger records up to 4Mb of data and stores it in non-volatile flash memory for later retrieval. Featuring an aluminum enclosure and conformal coating PCB, the Site-Log data logger has excellent performance in the harshest industrial environment. Featuring a 16-bit ADC and programmable input range, the Site-Log data loggers are well suited to science and laboratory applications where precise and accurate measurement is critical.

Description
The Site-Log datalogger range are portable battery powered data loggers which allow recording information and saving measurements to a 4MB flash memory for later retrieval. The internal lithium battery provides up to 10 years of instantaneous logging operation when sampling at interval of one minute. Site-Log data loggers features a wide sampling interval range from 20 milliseconds to 12 hours, providing alternative to data acquisition devices and paper chart recorders.

The 16-bit analog-to-digital converter makes the measurements more precise and accurate. Besides the on-board thermistor channel, the LPTH-1 logger has seven external thermistor input channels used to measure temperature. The following figure illustrates the correct input connections: 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. 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. Site-Log data logger also has a rugged, splash resistant aluminum enclosure and internal electronics are protected against moisture ingress by conformal coating. All Site-Log series data loggers come with an USB and an AUX ports. The USB port is for connecting directly to the computer. The AUX port is for connecting to a serial communication device like a Modem or an Serial Device Server when the logger needs to be accessed remotely.
SiteView Software
SiteView is a PC based application which works with Site-Log Series data loggers for downloading, configuration and data analysing and plotting. Its user-friendly graphic interface plus powerful functionalities fit both novice and advanced users. The versatility of custom equation and custom-line equation handle complicated measurement requirements.

Ethernet and Modem Support
There is an AUX port for connecting to a serial communication device like a Modem or an Serial Device Server when the logger needs to be accessed remotely. A SL-Rs232 converter cable is available that terminates in a standard RS232 connector. SL-RS232   SL-RS232 Converter is used to convert Site-Log data logger's TTL level communication signal to RS232 standard. Applications of SL-RS232 Converter: Computer only has COM port : If the computer does not have any USB port, or if you want to use COM port of the computer to communicate with a Site-Log data logger. Host device is not computer: If the host device is not a computer but it has a RS232 communications port.   RS232 to Ethernet Converters A range of general purpose RS232 to Ethernet or WiFi converters to allow the Site-Log range to be configured and read over a LAN or WiFi Network (requires the SL-RS232) More Information >>   WirelessCOM/G10 GPRS Modem The WirelessCOM/G10 will allow the Site-Log range to be configured and read remotely over a GPRS mobile phone network (requires the SL-RS232 and a suitable GPRS SIM Card)) More Information >>
