Core Technical Parameters

Main Product Features

3.1 Mature and Stable Speed Measurement Performance

The 3500/50 (133442-01) adopts mature and verified pulse sampling and frequency conversion algorithms, with stable and reliable measurement performance after long-term industrial field verification. It supports full-range speed detection from complete equipment standstill to high-speed operation, with accurate data output and low sampling error. The classic circuit design effectively adapts to conventional industrial operating conditions, ensuring continuous and stable speed monitoring for rotating machinery without data jitter or drift.

3.2 Dual Independent Redundant Monitoring Channels

The module is equipped with two physically isolated and electrically independent monitoring channels, which can realize dual redundant speed signal acquisition for a single rotating device or simultaneous speed monitoring of two independent equipment sets. Each channel supports separate parameter configuration, signal processing and fault judgment, forming a dual verification protection mechanism. It effectively avoids monitoring failure caused by single-channel abnormality and improves the overall reliability of machinery speed protection loops.

3.3 Complete Machinery Safety Protection Mechanism

Integrating multiple core protection functions, the 133442-01 module supports adjustable overspeed alert, critical overspeed trip, zero-speed standstill interlock and acceleration/deceleration anomaly monitoring. It can accurately capture abnormal operating states such as equipment overspeed runaway, sudden speed drop and abnormal startup, and output standard hardwired trip signals to trigger system interlock shutdown. This prevents mechanical failures such as blade collision, bearing burnout and equipment overload damage, ensuring safe operation of core rotating equipment.

3.4 Comprehensive Full-Loop Fault Self-Diagnosis

This module supports full-link real-time self-diagnosis covering field sensors, wiring circuits and internal hardware. It can accurately identify common faults including sensor disconnection, signal attenuation, pulse distortion and internal circuit failure, and generate standard fault codes and operation logs. The diagnostic data can be uploaded to the upper monitoring system in real time, helping maintenance personnel quickly locate faults and eliminate hidden dangers, ensuring the integrity and availability of the speed protection system.

3.3 Strong Industrial Environmental Adaptability

Adopting industrial-grade components and standardized EMC anti-interference design, the 133442-01 revision has excellent adaptability to conventional industrial environments. It can resist on-site electromagnetic interference, slight vibration and power fluctuation, ensuring stable signal acquisition and accurate data output in factory workshops and field equipment rooms. It supports 24/7 long-term continuous operation and meets the continuous monitoring requirements of industrial production equipment.

3.6 Simple Configuration and Low Operation Cost

All monitoring parameters, alarm thresholds and protection logic of the module can be remotely configured, calibrated and adjusted through the official 3500 system software. It supports real-time data viewing, historical trend recording and fault log query, facilitating daily equipment condition analysis and troubleshooting. Adopting standard rack plug-and-play installation, the module is easy to install, replace and debug, effectively reducing system operation and maintenance costs.
