附加组件
SSD -安全冲击检测(CHF 1133)
监视器可以提供集成的安全冲击检测(SSD)功能，通过德国劳氏认证，这比机械开关更可靠。
TFD -塔频检测(CHF 1116)
塔频检测(TFD)功能可以检测水泥塔的裂缝或塔基座的松动。监控器将不断监测塔的共振频率，任何变化都会触发警报，提醒涡轮机控制器。
基本传动系统监测(CHF 1115)
PCH 1026监视器提供fft分析，用于驱动系统的状态监测，包括涡轮机，主轴承，变速箱和发电机。
外部振动传感器
除了PCH 1026涡轮监视器的内置3轴加速度计外，您还可以连接多达四个单方向或双向外部传感器。这意味着监视器将满足您今天对传感器的需求，如果您将来需要更高级的监控，可以扩展。
外部单方向传感器，A (chb1102)
CHB 1100系列与PCH 1026风力涡轮机和结构振动监测器一起使用，用于高级机舱监测。

例如监测齿轮箱输出和发电机之间的低频扭转振动。

此外，CHB加速度计适用于齿轮箱高达1000hz的基本齿轮啮合监测。
传感器类型:电容式加速度计
频率范围:0.1 – 200hz (-1dB)
方向:单向、轴向
信号检测:峰值
灵敏度:300mv /g = 30.6 mV/m/s²
测量参数:加速度(m/s²)
外部双方向传感器，A和B (chb1101)
外部双向加速度计用于先进的机舱监测与分布式拾取点。

带有集成D-Sub和M12连接器的单独电缆使振动监测器的安装和连接非常容易。
传感器类型:电容式加速度计
频率范围:0.1 – 100hz (-1dB)
方向:垂直方向X, Y
信号检测:峰值
灵敏度:300mv /g = 30.6 mV/m/s²
测量参数:加速度(m/s²)

Add-ons

SSD – Safety Shock Detection (CHF 1133)

The monitor can be delivered with integrated Safety Shock Detection (SSD) functionality, certified by Germanischer Lloyd, which is more reliable than a mechanical switch.

TFD – Tower Frequency Detection (CHF 1116)

The Tower Frequency Detection (TFD) functionality detects cracks in cement towers or looseness in tower bases. The monitor will constantly monitor the resonance frequency of the tower, and any changes will trigger an alarm to alert the turbine controller.

Basic drive train monitoring (CHF 1115)

The PCH 1026 monitor offers FFT-analysis for condition monitoring of the drive train, including the turbine, main bearing, gearbox, and generator.

External vibration sensors

You can connect up to four external sensors in single or dual directions in addition to the PCH 1026 turbine monitor’s built-in 3-axis accelerometer. This means that the monitor will fit your need for sensors today and can be expanded if you need more advanced monitoring in the future.
External single direction sensor, A (CHB 1102)

The CHB 1100-series is used with the PCH 1026 wind turbine and structural vibration monitor for advanced nacelle monitoring.

Examples are monitoring of low frequency torsional vibrations between the gear box output and the generator.

Furthermore, the CHB accelerometer is suitable for basic gear mesh monitoring of the gear box up to 1000 Hz.

  • Sensor type: Capacitive accelerometer
  • Frequency range: 0.1–200 Hz (-1dB)
  • Directions: One direction, axial
  • Signal detection: Peak
  • Sensitivity: 300 mV/g = 30.6 mV/m/s²
  • Measuring parameter: Acceleration (m/s²)

External dual direction sensor, A & B (CHB 1101)

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

A separate cable with integrated D-Sub and M12 connector makes installation and connection to the vibration monitor very easy.

  • Sensor type: Capacitive accelerometer
  • Frequency range: 0.1–100 Hz (-1dB)
  • Directions: Perpendicular directions X, Y
  • Signal detection: Peak
  • Sensitivity: 300 mV/g = 30.6 mV/m/s²
  • Measuring parameter: Acceleration (m/s²)
