Zhong he XJZC-03A/Q Intelligent Speed Monitor Speed Measurement & Protection
The XJZC-03A/Q speed/impactor monitor receives two emergency trip signals while measuring rotational speed. This advanced monitoring system is designed for continuous monitoring and measurement of rotational speed in rotating machinery, simultaneously recording two emergency trip speeds. The output analog current signal and alarm contact signal enable easy integration with DCS, PLC systems, and paperless recorders.
The monitor processes two channels of impactor switch signals from the field, where a closed switch indicates engaged impactor status and an open switch indicates disengaged status. It also accommodates two high-level signal inputs.
Applications
Suitable for measuring rotational speed across all types of rotating machinery, including steam turbines and industrial rotating equipment.
Key Features
Advanced ARM high-performance embedded processor for superior measurement linearity, frequency response, and anti-interference capabilities
Dual configuration methods: host computer software or instrument button operation
Real-time recording of peak values detected by the monitor
Real-time recording of rotational speed values during impactor deployment and retraction
Comprehensive parameter configuration including meter number, range, number of teeth, transmission coefficients, alarm values, and output ranges
Permanent parameter storage after power outage
Power-on and power-off suppression functions with self-locking alarm output
Key-phase pulse signal output capability
RS485 communication interface with MODBUS-RTU protocol support
Industry Applications
Widely used in power generation, wind turbines, steel manufacturing, petrochemical industries, and other sectors requiring precise rotational speed monitoring and protection.
