Control and instrumentation
- Control
- Watlow controller with Hanse ChamberCore software, supplied with the system: programmable vibration ramps, GRMS level and test duration; can be synchronized with a chamber's temperature controller
- GRMS control
- From one accelerometer or the average of several, written straight to the Watlow controller for closed-loop control
- ChamberFFT (option)
- Vibration analysis on up to 16 IEPE accelerometer channels at 25,600 samples per second
Safety
- Interlock connection
- Shuts down vibration
- Emergency power off
- EPO shuts off system operation
Options
- More accelerometer channels — in groups of four, up to sixteen, with ChamberFFT.
- More accelerometers — Dytran 3030B5 with cable, and three-axis mounting blocks.
- Thermocouple inputs — 14 more product thermocouples, for 16 monitored and logged in ChamberCore.
- Fixtures — designed for your product, Metric or English layout.
- Enclosure top — manual or automatic opening, with ports or view windows.
- Chamber integration — the same table built into a VTC chamber, or supplied as a VK kit for a chamber you own.
Warranty and support
- 3-year warranty on vibrators and vibration tables.
- 1-year equipment warranty from shipment: parts and labor for the first 90 days, then parts at no cost other than travel.
- Supported for the long term — including controller retrofits for older systems.
- Built in Allegan, Michigan — designed, fabricated and supported in the US since 1993.
