These specialist data loggers and accessories are tailored for the electricity energy sector and facilitate the metering and recording of AC voltage, current and temperature using a single comprehensive and accurate instrument.
Squirrel 1010/1010X and 1020/1020X energy series dataloggers and accessories enable quick, easy metering, monitoring and logging of load usage patterns enabling optimisation of power distribution, ultimately leading to improved reliability of power availability and power distribution plant costs.
The Squirrel 651 datalogger is specially designed for use with the Northern Design NDRail350 (1 x 3 phase load) or NDRail310 (3 x single phase load) energy meters.
|Squirrel Model||Channel Configuration
(Number and type of sensor)
|Case depth mm|
|1010||6 AC voltage + 2 thermistor / AC voltage||60|
|1020||12 AC voltage + 4 thermistor / AC voltage||85|
|651||A maximum of three NDRail350s (1 x 3 phase load) or three NDRail310 (3 x 1 phase load) can be connected simultaneously to the logger.||60|
Optional Text message on alarm using and /or remote access, using external GSM modem.
The memory can be expanded to 2M readings (about 2,080,000).
Don't forget that a lot of memory takes time to download and that it is possible to reduce the amount of memory used for a logging run. Eltek loggers download at 38400 baud, and in practice this is about 500 readings per second.
The IP65 enclosure is fitted with oversized weather secure glands allowing the Din connector termination of the Rogowski Coil or temperature probe to pass through. All metal fittings of the enclosure are high grade stainless steel assuring reliable and durable usage.
