Multiple sensor compatibility: Compatible with a variety of turbine sensors, such as the PR6422 to PR6426 series
Protection function: With open and short circuit protection, and reverse protection
Stability: Temperature drift and time drift small, to ensure long-term stability
Step 6: Function
Vibration monitoring: mainly used to monitor the shaft vibration of rotating machinery, such as steam turbines, generators, etc
Fault diagnosis: Help diagnose mechanical faults and prevent potential problems by monitoring vibration signals
Improve operating efficiency: Timely detection and resolution of vibration problems, reduce downtime, and improve the operating efficiency and reliability of equipment
1. Parameters
Input: Turbine Sensor PR6422/… ~ PR6426/…
Output: The AC voltage signal superimposed on the DC voltage is proportional to the shaft vibration
Output voltage linear range: -4… -20V (supply voltage is -24V); Wide range: -1… -22V; Specific output: -12V (symmetrical measurement range at both ends)
Internal resistance: 100kΩ
Response time: 15
Accuracy: The linear error depends on the connected sensor model, for example, the connected sensor PR6422 ≤1.5%, PR6423 ≤1.0% ≤2%, PR6424 ≤1.5% ≤2%, PR6425 ≤6.0%
Temperature drift: zero 200mV/100K; Sensitivity <2%/100K
Time drift: greater than 0.3%
Error of supply voltage: <0.2%/V
