Power Parameters has announced the release of the Hioki LR8432 logger for heat flow (watts/m2) and temperature.
The LR8432 provides a new level of sensitivity with voltage/heat flow measurement ranges down to 10 mV f.s.
This capability ensures its ability to deliver accurate, reliable measurement, even of targets with small temperature changes.
The sensors used to measure heat flows (heat flow sensors) have different sensitivities, and in the past it was necessary to calculate and set the conversion ratio for each 1 V of output based on the sensitivity constant. The LR8432’s configuration process improves work efficiency by requiring only that the sensitivity constant be input.
Hioki HiLOGGER LR8432, which is a ten-channel data logger is palm-size and suitable for tasks including HVAC, industrial, and electric vehicle monitoring.
The Hioki HiLOGGER LR8432 data loggers can be powered by an optional trickle-charged NIMH battery pack. The Hioki LR8432 data loggers have 10 analogue data channels and 4 digital input channels.
Analogue channels are fully floating being isolated from ground and from each other. The inputs are suitable for thermocouples (K, J, E, T, N, R, S, B) and voltages from 100 mV full scale to 100 V full scale.
A single channel programmable output alarm is provided. The measurement function utilises a delta-sigma A/D, digital filtering and Hioki proprietary over-sampling technology to provide clean signals and easily discernable trends.
The additional four digital channels are suitable for rev counters, pulse counters, etc. Minimum simultaneous sampling interval is 10 milli-seconds (ms), and maximum is 1 hour. With 10 ms sampling time, the 7MB internal memory permits 32 minutes of recording.
Hioki data loggers are available with Hioki CF storage cards (512 MB, 1 GB and 2 GB) that extend storage time to in excess of six days at 10 ms sampling time (2 GB). Furthermore within a two-minute period, full CF cards can be replaced with new ones without stopping the recording process (note: the remaining recording time is displayable on the TFT colour display).
The Hioki HiLOGGER LR8432 data loggers are supplied with a logger utility package suitable for PCs.
Up to five loggers can be interfaced via USB hub to a PC for simultaneous real-time recording, data processing and operations including scroll-back.
