Product Performance

Reliable monitoring accuracy: ±1% FS measurement accuracy combined with wide range adaptability can accurately capture small changes in shaft differential expansion, meeting the monitoring needs during startup and steady-state operation of steam turbines. Strong system compatibility: Supports access of multiple types of sensors such as eddy current and LVDT; can directly link with VM-5 series racks and third-party control systems without signal converters, with data transmission delay ≤100ms.

Outstanding operational reliability: Built-in redundant power supply design (rack-mount type) and full-time self-diagnosis function can real-time monitor module and sensor abnormalities, with fault response time ≤50ms and Mean Time Between Failures (MTBF) ≥5×10⁴ hours. High operational convenience: Front-panel LCD display and buttons enable full-process non-shutdown operation for parameter configuration and alarm query; supports storage and export of 100 sets of historical alarm data.

Excellent environmental adaptability: 0-65℃ operating temperature covers industrial on-site temperature range; vibration and shock resistance design complies with IEC standards, enabling stable operation in complex working conditions such as power plants and petrochemical industries.
