Product Introduction

technical parameter
Input: Can connect turbine sensor PR6422/...~ PR6426/...。
Output: The output is an AC voltage signal proportional to shaft vibration superimposed on a DC voltage, with open circuit, short circuit, and reverse protection functions. The linear range of output voltage is -4V to -20V (when the supply voltage is -24V), and the maximum range of output voltage is -1V to -22V. The output voltage is measured symmetrically at both ends with -12V, and the internal resistance is 100k.

accuracy
Linear error: ≤ 1.5% when connecting sensor PR6422; ≤ 1.0% when connecting sensor PR6423; ≤ 1.5% when connecting sensor PR6424; ≤ 6.0% when connecting sensor PR6425; ≤ 1.5% when connecting sensor PR6426.
Temperature drift: Zero point 200mV/100K, sensitivity<2%/100K.
Time drift: maximum 0.3%.
Power supply voltage error: ＜ 0.2%/V.

Functional Features
Multi signal conversion capability: capable of receiving specific signals generated by eddy current sensors and converting them into standard output signals, such as analog voltage, enabling flexible signal conversion.
High precision measurement: Using advanced measurement technology and high-precision sensor components, it can provide accurate and reliable signal conversion results, ensuring a linear and accurate proportional relationship between the output signal and the input signal.
Wide dynamic range: can adapt to different signal amplitudes and measurement requirements, can handle the conversion from small signals to large signals, and maintain high measurement accuracy and stability.
Fast response and stability: With fast response speed and stable performance, it can accurately convert input signals in real time and output conversion results in a timely manner, maintaining stable working performance under various environmental conditions.

application area 
Displacement measurement: can be used to measure axial and radial shaft displacement, shaft eccentricity, etc., for example, in rotating mechanical equipment such as steam turbines and compressors, to monitor changes in shaft position.
Vibration monitoring: It can measure the vibration of machine shafts and shell components, monitor the vibration status of rotating machinery in real time, and prevent mechanical failures.
Wear detection: It can be used to detect the wear of thrust bearings and indirectly reflect the working status of bearings through oil film measurement.
Other measurements: can also be applied to crack detection, non-contact measurement of speed and rotation direction, differential expansion, bearing seat expansion, valve position measurement, etc.
