Battery power supply and sensor simulator for IEPE accelerometers
Expanding the company's range of accelerometers and instrumentation, DJB Instruments has introduced two IEPE accessories. The VB/01 is a low cost battery powered single channel IEPE accelerometer supply which provides 4mA constant current supply at 18V DC. With LED indicators for power, short circuit and open circuit, it is suited for field testing where no mains power is available.
The 8401 IEPE sensor simulator is the first in a range of simulator products due for launch in 2014. The 8401 installs in place of an IEPE accelerometer (or other sensor) and accepts signals from a voltage function generator. This allows the user to verify signal conditioning settings and cable integrity, the 8401 uses the power from the IEPE signal conditioning to complete the checks.
Gary Chadwick, Technical Manager, DJB Instruments, commented: "Though these products are far from unique we have tried to improve their cost effectiveness and the amount of sensor feedback available to the user. At the same time we have used them as the basis for new products that will create genuine progression through integrating multiple requirements into one product."
The VB/01 battery powered single channel IEPE accelerometer supply and 8401 IEPE sensor simulator are available now.
