Bearing fault detectors
The PCH 1420 offers both broadband high frequency monitoring, Envelope, Kurtosis and Crest factor for bearing fault detection.
All the detectors run simultaneously and are based on inputs from up to 4 measuring points in real time. Each bearing fault detector can measure the various fault indicators throughout the lifetime of the bearing.

4 input channels, 2 process channel and 1 tacho input channel
The four input channels are factory configured and calibrated prior to delivery. Gain factors are automatically configured with no user action required.
The vibration monitor has one embedded process channel and one tacho input channel. The process and Tacho channels are updated simultaneously with the four vibration input channels.

5 embedded outputs for optimal safety
The vibration monitor has five embedded outputs. Measuring values and alarms can be directed to the four digital outputs.
The fifth output, a redundant mechanical failure relay, will open in the event of missing sensors, sensors being out of range, short-circuits or general monitor errors.

Redundant relay for trip alarms
The monitor design features a redundant isolated system failure relay, which you can use for trip alarms from all measuring bands configured with individual trip alarms.
Self-test procedures
You can also activate a self-test procedure through a digital input or through user software for testing the monitor and the outputs. This ensures a highly reliable data output and reduces the test cycle duration.
Advanced alarm functionality
When an alarm limit is exceeded, integrated alarms alert the user through a connected rotor light, a beeper, a control system, or by directly shutting down the machine.
LED lights on the front of the monitor clearly show the status of the four measuring channels, while a status LED light indicates general errors or failure conditions.
In the event of vibration alarms, the affected channel will turn yellow to indicate the alert level or red to indicate the danger level.
In the event of a sensor error or an overload, the individual LED for the affected channel will flash red, and the status LED will turn permanently red as well. Alarms or input errors from the process inputs will turn the status LED red.
The alarm functions can also be configured as needed.

Complementary software interface for analysis and individual setup
You can use the monitor’s standard setup out of the box or easily adapt the setup to your specific requirements using the PCH Vibration Studio software, which comes complementary with the monitor.
We offer several versions and configurations to provide you with a suitable solution for your specific application.
The complementary PCH Vibration Studio software provides online trending, simultaneous recordings of four time waveform signals (raw data), and an FFT tool for diagnostics and analysis.
The software is user-friendly, and you can connect a USB cable or a permanent RS-485 wire for remote access.
You access the PCH 1420 easily through the embedded USB 2.0 connector on the front of the monitor. The monitor settings are imported to your computer, and you can alter them from here.
The PCH 1420 also offers an RS485 2-wire connection for long distances and can be daisy-chained into a network of monitors.
The RS485 connection is used for the PCH Vibration Studio software and for the optional PCH EtherBridge LAN/TCP module (remote access).
A switch on the front of the PCH 1420 activates an internal 120 Ohms resistor in order to terminate the RS485 network.
