PURPOSE:To relieve the load of an operator, by connecting the 2nd compressor circuit to the poststage of the 1st compressor circuit in a controller used for an electric or an electrohydraulic vibration tester to automate the adjusting operation. CONSTITUTION:The 2nd compressor circuit 32 is connected to the poststage of the 1st compressor circuit 12 and they are operated by two integration comparing and calculating circuits 11, 13. When the vibrating input is increased, the operating point is shifted only by a half at the compressor circuits 12, 32. Thus, the far broader dynamic range is attained and complete automation is realized. |
