PCH 1026 Digital Wind Turbine Monitor

Product catalog summary

Overview: The PCH 1026 is a digital wind turbine monitor designed for low-frequency structural vibration monitoring. It is housed in a sealed, rugged box and requires only a DC power supply and output connections to function. The monitor is based on a digital platform, allowing for easy configuration changes via PC software.

Specifications:

Filters: Includes 8th order Butterworth and other special filters. Custom solutions can be uploaded, such as a Low Pass filter at 30Hz complying with ISO 4866.
FFT Analysis: Zoom FFT available for tower frequency tracking and basic drive train monitoring. Supports 1 channel with 400 lines or 2 channels with 200 lines.
Signal Detection: True RMS with averaging time of 0.01 - 100 s, Peak or Peak-Peak with attack time of 1 - 1000 ms, and decay time of 0.1 - 100 s.
Alarm & System Failure Relays: Configurable alarm relays up to 4, with selectable alert/danger, latch/non-latch, delay time, and make/brake function. Failsafe system failure relay for internal watchdog detected failures.
Analog Outputs: Up to 4 outputs, 4-20 mA relative to measuring range, 0-100%.

Power and Dimensions:

Power Supply: 20-30 V DC, max power consumption 7 W.
Dimensions: 254x130x66 mm, weight approximately 2 kg.

Input Sensors: Supports up to 4 input channels, with internal accelerometers in directions A, B, and/or C, and external accelerometers up to 4. Dynamic range of ± 6 g, peak.

Measuring Parameters: Measures acceleration, velocity, and optionally displacement. Overall frequency range of 0.1 - 200 Hz, with an optional range of 0.1 - 1000 Hz for 2 bands.

Signal Conditioning: Digital signal conditioning with configurable settings via PC software. Supports up to 12 simultaneous conditioning bands.

Interfaces:

RS-232 and RS-485: Complies with IEA-232 and IEA-485 standards, respectively. Supports Modbus RTU communication.

Compliance and Safety: CE marked for EMC and Low Voltage Directive compliance. Safety standards include EN61010-1 and IEC 61010-1. EMC emission and immunity standards are also met.

Environmental Specifications:

Temperature: Operating range of -20 °C to +50 °C, with optional cold environment range of -30 °C to +60 °C.
Humidity: 95% RH at 40 °C for both operating and storage conditions.
Mechanical: Vibration, shock, and bump resistance as per IEC standards.

Optional Features: Includes R&D Starter Kit, Safety Shock Detection, Tower Frequency Detection, and basic drive train monitoring. External sensors are also available.
