The PCH1026 GE is a digital structural vibration monitor manufactured by General Electric (GE). The equipment is mainly used to monitor the vibration level of rotating equipment (such as pumps, fans, compressors, generators, etc.) to assess the operating status and health of the equipment.

USES
• Permanent monitoring of low frequency structural
and seismic vibrations
APPLICATIONS
• Wind turbines – Tower vibrations – Drive Train oscillations (pitch turbines) – Edgewise blade vibrations (stall turbines)
• Steel towers
• Chimneys
• Bridges• Buildings – Seismic vibrations according to ISO4866
CONFIGURATION & SETUP
• Setup and configuration can be performed via
seriel RS-232 port using the supplied setup and
monitoring PC program CHT 1012. All settings
can be changed on site.
• Setup and Display can also be performed remote
through optional RS-485 connection from external
PC or controller, e.g. WTC or Process controller
• A log in the PC software keeps record of the
settings in the particular monitor, identified by
instrument serial no.

CONFIGURATION
PCH 1026 is a selfcontained monitor in a
sealed, rugged box. To function only a DC
power supply and desired output connections
are required. PCH 1026 is designed for low
frequency monitoring applications.
Built in vibration sensors in 3 directions: X, Y
and Z.
Including test functions for all sensors and
electronic circuits as well as internal watchdog
for continously self-monitoring functions.
The design of PCH 1026 is based on a digital
platform allowing multiple customer solutions,
and easy rapid change of configuration and
settings, also in the field.

Alarm Relays:
PCH 1026 offers 4 independent Alarm relays
with programmable Make or Break functions.
All 4 relays can be assigned to the desired
frequency or measuring direction. E.g. either
one relay pr. frequency of interest or up to 4
different frequencies on the same relay. Alarm
threshold level, delay time and latch or non
latch function can be setup independently for
each relay using the supplied PC software.
System Failure Relay:
PCH 1026 offers a System Failure relay with
Break function for optimal fail-safe
configuration. Failures inside the PCH 1026,
detected by the internal watchdog, either in
Test mode or in Monitoring mode, will cause
the System Failure relay to trigger. The System
Failure relay reacts to: Power Failure,
Overloads, Processor halted, Defective
sensors.
For all 5 relays:
