Control sampling device PC-UPO

The PC-UPR monitoring device (hereinafter referred to as the device) is designed to work as a portable device providing control of signal parameters in the UPR loop by non-contact method directly on the railway track. The device is not a standardised measuring instrument and is intended for operation in tunnels at metro stations. The device is intended to replace the device PC UPR 140.00.000.00, which is in operation in the metro. Operating conditions: operating temperature of ambient air from -10 deg C to +50 deg C. C to +50 deg. C; relative humidity up to 95 per cent at 35 deg. C and lower temperatures without moisture condensation; in terms of resistance to mechanical effects occurring during operation, the product corresponds to group MM5 according to OST 32.146-2000. Main technical data: The device measures the average value of the magnetic field induction created by the alternating current flowing in the loop. The carrier frequency of the alternating current in the loop in the range from 95 kHz to...
