Low-frequency vibration and seismic structural monitoring system
PCH 1026
PCH Engineering A/S
The PCH 1026 can monitor vibration in buildings according to ISO 4866.
The PCH 1026 is an all digital vibration monitor. It has 3 internal sensors (accelerometers) allowing for measurements in 3 directions (X, Y and Z), each with independent conditioning channels available. However, also 2 or 3 conditioning channels can be assigned to just one sensor, i.e. one direction, if signals of different frequencies have the strongest appearance in the same direction.
The PCH 1026 is equipped with proven filter techniques, based on experience with many applications, especially in windturbines. PCH 1026 offers a set of outputs, i.e. up to 4 independent industrial 4-20 mA outputs, up to 4 independent alarm relays plus 1 System Failure relay and a serial RS-232/RS-485 port for connection to a Controller or PC.
PCH 1026 is supplied with a PC program, which makes setup and configuration of the monitor a very easy task to do.
As an option for OEM customer solutions the PCH 1026 can be equipped with an interface for various Bus communication types, such as CANopen, InterBUS, ProfiBUS, DeviceNET, etc.
The PCH 1026 comprises a test function which can be used to test both the internal sensors (accelerometers) as well as the outputs of the monitor. It reports to any connected controller by means of the System Failure relay and the serial port.
