1、 Core function: Full cycle monitoring and three-dimensional protection

1. Dual dimensional vibration monitoring

vertical+Horizontal synchronous measurement: through matchingLHThe series of magneto electric vibration speed sensors can simultaneously capture axial and radial vibration data of rotating machinery, accurately locate the source of faults (such as bearing wear and rotor imbalance).

Intensity and displacement can be freely switched: supports vibration intensity（mm/s rms）Compared to vibration amplitude（μm pk-pk）Dual parameter display, meeting different industry standard requirements (such asISO 10816Vibration standards).

Application case: In the monitoring of blast furnace fans in a certain steel enterprise, vertical intensity was analyzed simultaneously（3.2mm/s）Horizontal displacement（45μm）Successfully diagnosed the rotor misalignment fault, avoiding unplanned downtime losses exceeding one million yuan.

2. Three level alarm protection mechanism

pre-alarm+Danger alarm+Shutdown protection: Users can independently set two-level thresholds (such as pre alarm)8mm/sDanger alarm12mm/s）When the vibration exceeds the limit, the instrument will trigger sound and light alarms in sequenceDCSSystem linkage, relay output shutdown signal.

Delay suppression function: Supports1-60The second alarm delay setting effectively filters out instantaneous interference (such as device startup shock) and reduces the misoperation rate90%.

Technical advantage: Alarm contact capacity reachesAC220V/3AIt can directly drive the contactor without the need for intermediate relays, simplifying the control circuit.

3. Intelligent signal processing

Sensor disconnection detection: Real time monitoring of sensor connection status, automatic cut-off of alarm output in case of disconnection, to avoid false protection.

Power on self-test function: automatically detects the hardware status of the instrument when turned on, and displays fault codes intuitively (such asE01Sensor malfunctionE02Power supply abnormality).

4-20mAStandard output: driven by current signal500ΩLoad, seamlessly integratedDCSThePLCThe system enables remote monitoring and data analysis.
