BNC connector type compact charge converter
High-sensitivity output of 10mV/pC
The newly developed charge converter "CH-6140" receives a constant current (2mA) from an FFT analyzer or DAT, achieving a high-sensitivity output 10 times greater (10mV/pC) than the conventional "CH-6130 (released in July 1999)". In addition to the convenience of space saving in field measurements, it enables the use of small sensors with low output and measurement of minute vibrations. To make it easy to carry and route, it inherits the conventional design philosophy of combining the functions of a connector conversion adapter and a charge amplifier. By making the housing the same as the "CH-6130" (total length 40mm, weight approximately 20g), efforts have been made to integrate the equipment and save space. Furthermore, because it converts the miniature connector to a BNC connector, it can be directly connected to FFT analyzers and DATs (with constant current drive support) that are widespread in the field, and its power becomes more apparent as the number of channels to be measured increases.
The CH-6140 charge converter, when combined with Ono Sokki 's charge output type Accelerometer (NP-2000 series), enables the construction of a sensing system with high shock resistance (up to 10,000 m/s² or more) and a wide temperature range (-20 to +160°C). Furthermore, by directly connecting it to portable FFT analyzers such as the CF-3000 series and vibration comparators such as the VC-2100, advanced measurements can be easily performed in a variety of environments.
