PEN RECORDER
PR8111, PR8112

Corrosion Protection Maintenance of Railroad Tracks

Electrical corrosion protection maintenance often requires recording waveforms outdoors and the recorded waveforms sometimes need to be stored for long periods of time. The PR8111 Pen Recorder’s wide ranges, from highly-sensitive (1mV Range) to high voltage (250V Range), gives you the flexibility to use it in broad applications. The pen recorder is also used for leakage current measurement between the track or rail and buried facilities of DC electric railroads. The battery power functionality lets you use the PR8111 to record anywhere in the field.

Environmental Testing

Pen recorders are also widely used as recorders of measuring instruments for environmental testing. Since the recorder can be powered by batteries, it is particularly useful for recording outdoors without concern for AC power. Connect the following environmental sensors to record a variety of signals to conduct analysis and troubleshoot issues:

Sound level meter: Record noise in the vicinity of an airport
Illuminometer: Record changes during sunlight hours as a result of the construction of elevated railway tracks
Odor meter: Inspect deodorization equipment
Water quality meter: Monitor wastewater and inspect groundwater and hot spring water
Thermometer: Environmental assessment for agriculture
Power analyzer: Inspect power quality for railways
Anemometer: Conduct safety management for cranes and railways
Magnetic field meter: Identify the influence of a power line on the human body
