Abstract	In the course of upgrading Instrumentation of extracted beams at IHEP the new beam profile monitoring system has been developed and comissioned. It incorporates many improvements towards lower amount of monitor substance to be placed in the beam path, lower cable expenses, higher radiation and noisy resistance, wider dynamic range. New circuitry allows one to measure profiles separately for each extraction in one machine cycle. The system has a capability for multiple measures of beam profile during the slow extraction for exploring dynamic effects. The paper describes hardware and software of system.
