STRAY CURRENTS RECORDER RPB-1
Product Description
Description of product
Stray currents recorder RPB-1 is designed for measurement of direct and alternating stray currents intensity in rock shooting sites and blasting agents storage places. It fully meets the requirements of PN-G-02700-1 and PN-G-02700-3 standards. The recorder shows the effective value of long-lasting current ( > 0.4 s) which reflects the thermal effects in the connected receiver. It measures the total effective current value, the value of direct component and the effective value of alternating component. Another function of the device is the detection of short lasting current pulses (below 110 ms) and comparing the energy of such pulses with the pulse permitted for the applied electrical detonating fuse. Such measurements allow an assessment of the hazard of an electrical fuse blast-off. The assessment is made for the selected fuse class: ZE 0.2A , ZE 0.45A , ZE 2A , ZE 4A.
The stray currents recorder is a universal device designed for use in underground and open-cast mines. It is a category M2 device and may thus be used in all underground mines with methane or coal dust explosion hazard. If explosive atmosphere is present, the device may not be used.
The device may be used by electric service crews taking periodic measurements and by blasting service personnel when an immediate measurement is required. In RPB-1 version with memory there are two other modes available: “special measurement” and “explosive materials storage recorder” where periodic measurements are made and recorded. The measurement results are stored in the internal memory. They may at any time be viewed and transmitted to a PC for further analysis.

The recorder is supplied with a computer program (and communication cable) which enables, among other things:
– sending measurement results do a PC,
– supplementing measurements with measurement points,
– creating and printing stray currents measurement reports.
The recorder is a portable device, battery powered and enclosed in a plastic casing. It is produced in a version with built-in memory and without memory.
