【英文介绍】
DIGITAL WINDTURBINE STRUCTURAL VIBRATION MONITOR
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.
FEATURES
· 3 internal vibration sensors (accelerometers)
· Triaxial measurements in A, B and C directions
· OmniDirectional Tower Monitoring
- Proven optimal monitoring of towers
· Facilitates monitoring of up to 4 different frequencies
indpendently, either one from each sensor or up to 4
different frequencies from one sensor
· Proven filter techniques, based on experience with
windturbine applications
· Measures RMS, Max. Peak or Peak-Peak values
· 1 - 4 independent industrial standard 4-20mA outputs
· 4 independent Alarm relays with programmable
make/break function and 1 System Failure relay
· Programmable Alarm thresholds and Delay times
independently for each Alarm Relay
· Internal constant watchdog of both sensors and
electronic circuits. Failures are indicated on the failsafe System Failure relay
· Test function for all sensors and electronic circuits.
· Designed for rough environments, both regarding
temperature, electric noise interference and humidity.
· Possibility of implementation of customer defined
monitoring algorithms, alowing customers to differ
from their competitors
