The CHB 1101 transmitter is an external bi-directional low frequency accelerometer for use with the PCH 1026 mk2 wind turbine and structural vibration monitor.

The external bi-directional accelerometer is used for advanced nacelle monitoring with distributed pick-up points.

Separate cables with integrated D-Sub and M12 connectors make installation and connection of the vibration monitor very simple.

Easy to install

The CHB 1101 has an internal www.cniacs.com memory chip which stores factory information: serial number, model number, sensitivity and self-test parameters.

When the CHB 1101 is connected, the monitor reads the information in the memory chip and automatically adapts to the settings of the particular sensor.

This means that the accelerometer can be freely replaced without having to manually change the parameters.

The monitor reads the chip every 30 seconds to verify that the accelerometer is still connected and recognised.

The monitor will stabilise for 20 seconds after power is applied.

The stabilisation time after disconnecting/connecting the CHB 1101 is 3 seconds. During settling, the PCH 1026 Mk2 will perform a self-test of the internal and external accelerometers.

Self-Test

The monitor will issue a system error message if the self-test fails or the accelerometer is disconnected.

Accelerometers must be specified in the PCH 1026 Vibration Monitor setup to use this feature.

The CHB 1101 accelerometer is an optional feature of the PCH 1026 Mk2 Wind Turbine and Structural Vibration Monitor.
