Testing the entire measurement channel via system testing or loop checks is the most important function of a Portable Shaker Table. By testing the transducer along with its cabling and data acquisition programming, technicians can identify errors like improper scaling or triboelectric noise before they become bigger problems. Specified within the American Petroleum Institute Standard 670 (API 670), all Portable Shaker Tables from The Modal Shop are closed loop variable amplitude and frequency as well as programmable, reducing the time required to perform repetitive tests. Each Portable Shaker Table is long-life battery powered, rugged, accurate, NIST traceable and supplied with an accuracy calibration certificate accredited by the A2LA to ISO 17025.
We also carry Portable Vibration Calibrators for test and measurement.
Portable Shaker Tables are ideal for loop checking vibration monitoring systems and testing accelerometers, velocity transducers, and proximity probes over a wide frequency range, from 5 Hz to 10 kHz.
Low Frequency Portable Shaker Tables are designed to field test sensors and vibration alarms on critical slow speed machinery by simulating actual machine vibration, from 0.7 Hz to 2 kHz.
Accessories to help with mounting a variety of sensors and performing proximity probe calibrations are available:
