Product details
Overview
A cost-effective black box expert online vibration monitoring system PCH1028 is a set of local and remote monitoring systems designed to provide advanced, automatic fault prevention,
Continuous monitoring of key mechanical equipment that operates continuously 24 hours a day, 365 days a year Typical applications include bearing faults and fault types, special gear faults, dents, unbalance, and misalignment,
Early prediction of fatigue and other issues Can monitor key mechanical equipment such as: ★ Various types of industrial gear systems ★ Various types of pump systems ★
Transmission mechanisms for various types of wind power turbines ★ Various types of rolling mills and mills ★ Various types of gas turbines ★ Various types of compressors
Application scope of vibration monitoring instrument
● Industrial gear system
● Pump system
● Transmission mechanism of wind power turbine
● Rolling mill and milling machine
● Gas turbine
● Compressor
Functions and advantages of vibration monitoring instrument
Each PCH1028 can operate independently, including vibration monitoring for 2 to 4 channels, and optional process parameter monitoring for 4 channels. Signal processing is based on embedded FFT technology, including real-time 800 line fully refined FFT, envelope analysis, and inverse spectrum. All diagnostic analysis functions are directly executed within the monitor.
● Unique alarm function with 192 different machine component fault information, which can be directly sent to the machine controller or control center using industrial communication standards.
Based on alarm information or vibration changes, manually control the monitoring instrument at any time to record and store trend information and spectra. Equipped with optional memory, each channel can store real-time waveforms for up to 8 seconds (19.2 kHz bandwidth). The optional accessories also include speed input and trigger input modules.
●
CHT1009 is a database and analysis management software based on network control, which is a standard configuration of the system.
It is used to set the monitor and download storage information. When connected to the monitor online, CH1009 software can send monitoring status and alarm reports through the Internet, including storage management service (SMS) information; This software can also
Display waveform spectrum status and alarm information by connecting to any local area network or standard web browser.
● All control functions (such as changing internal settings and observing spectrum) can be performed online via the Internet.
Characteristics of vibration monitoring instruments

Alarm relay PCH1028 provides 4 independent alarm relays with establishment/interruption functions. All 4 relays can specify the required frequency. Using CHT1009 software, individual alarm thresholds can be set for each relay to verify and lock or unlock functions. System malfunction relay PCH1028 provides a system fault relay with interrupt function for optimal automatic fault prevention configuration. Various internal faults are detected by the built-in electronic monitoring device. Whether in test mode or monitoring mode, the system fault relay will be triggered to respond to power failure, overload, processor pause, sensor damage, and other faults. DC output PCH1028 provides 2 to 4 independent 4-20mA/0-5V industrial standard outputs for connecting programmable logic controllers (PLCs) or computers.
