Meters of codes, current parameters ALSN RPK-7132, etc.

Current indicator of rail circuits IRC-25/50m
The device is designed to evaluate and indicate the signal current level of ALSN code signals at a selected frequency in the rail circuit (25 Hz; 50 Hz), the duration of the first short interval of the Tc, the duration of the Tc code cycle and the type of code (Z, W or QL) by inductive method, as well as the level of magnetization of the rail in the field.

ALSN IPK-1132 Code Parameter Meter
Designed for:

• visual display of the form of the code parcels of the ALSN current and the envelope of the code current on the screen of the liquid crystal indicator (LCD);
• determination of time and amplitude parameters of ALSN codes;
• records of the form of code parcels of the ALSN current in the device memory for later viewing.

• with built-in inductive current sensor;
• with the help of current tongs;
• using measuring probes from measuring inputs in the form of AC voltage pulses.

Meter-recorder of ALSN RPK-7132 codes parameters
RPK ALSN is designed for continuous recording of ALSN code signals from locomotive coils when moving a locomotive (trolley). RPC ALSN can be used to detect ALSN failures in floor SCB devices and locomotive devices, the causes of which may be distortion of code pulses (distortion of time parameters, amplitude distortion, filling of code intervals from extraneous sources, etc.). In addition, such measurements can be made for preventive purposes for objective quality control of coding of rail circuits.

Traction Current Asymmetry Meter IAS-1111 / IAS-1121
The devices are designed to measure, graphically display and store the following parameters in memory:

• traction currents simultaneously through two channels;
• traction current differences;
• coefficient of asymmetry of traction currents.
