Product features
- Two speed channels+one eccentric channel, simultaneously monitoring speed, acceleration, rotation direction, zero speed, and shaft eccentric bending, compatible with magneto electric speed sensors and eddy current probes.
- The speed supports four alarm thresholds (HH/H/L/LL) and can be configured with overspeed, low-speed, and zero speed protection; Eccentricity has two levels of warning and danger alarm, with a software adjustable alarm delay of 0-99 seconds to avoid false start stop alarms.
- Output phase reference marker signal, which can be supplied to VM-7 series analysis module for vibration phase analysis.
- Standard 4-20mA analog output, real-time values of speed and eccentricity uploaded to DCS; Relay dry contact output, directly connected to ETS interlocking protection circuit.
- Support hot swapping, the rack can replace modules without power on, without affecting the operation of other monitoring modules in the rack; Panel LED indicator light, displaying channel normal, alarm, and probe fault status.
- MCL View software configuration, modify range, alarm value, delay parameters, and read fault records; Optional/TB1 front plug terminal,/NB1 non explosion proof,/TRP tropical high temperature version, suitable for different project working conditions.

Usage Scenarios
- TSI system for steam turbines in thermal and gas-fired power plants, including unit speed monitoring, overspeed protection, zero speed interlocking, and rotor eccentric bending monitoring.
- Petrochemical refining turbine centrifugal compressor unit, turbine drive equipment speed protection, rotor thermal bending monitoring.
- Large rotating equipment in coal chemical and oil and gas factories, ETS protection system speed signal acquisition.
- Stock Shinkawa VM-761B rack system, VM-703B module is damaged and replaced with spare parts, reusing the original probes, wiring, and configuration parameters.
- Monitor the eccentricity of the rotor during the start-up and shutdown conditions of the unit, prevent the bending of the main shaft, and provide measurement conditions for the start-up interlock.
