Single Channel Analog Voltage and Current Loop Recorders

The Telog AVR-31 converts DC voltage inputs into a series of amplitude values and stores them in its solid state memory. At a user specified interval ranging from one second to every eight hours, the recorder can compute and store any of the minimum, average, maximum and/or total values.

The Telog ILR-31 converts current loop inputs into a series of amplitude values and stores them in its wraparound memory. When data averages are selected as part of the statistical analysis program, two types of data totals can be computed: Period and cumulative totals.
