About Instrumented Sensor Technology
Instrumented Sensor Technology, Inc. (IST) is an engineering company in Okemos, Michigan, that has designed and built portable, battery-powered data recorders for shock, vibration and motion measurement since 1987. Founder and president Greg Hoshal leads the company, which develops both the recording hardware and the Windows analysis software that turns field data into engineering results.
What IST makes
IST recorders are meant to be mounted on a shipment, vehicle, structure or test article and left unattended for days to months. Most models carry built-in accelerometers, so no separate data acquisition system is needed, and several also accept external IEPE sensors for precise placement.
The lineup scales with the question being asked. ShockTimer indicators and VibTimer-Plus loggers audit how carriers handle freight at low cost per unit. SnapShock-PLUS recorders capture peak g, duration and velocity change for drop-height and impact studies. Full-waveform recorders such as the EDR-5, with up to 64 GB of memory and IP67 protection, store complete triaxial time histories for PSD analysis and test specification work. Specialty units measure six-degree-of-freedom motion, helmet impacts and atmospheric pressure during parachute descent.
IST also rents most of its recorders, and it offers recalibration, logistics quality audits and an in-house shock, vibration and environmental test lab for prototype and pre-compliance work.
Why engineers specify IST
- Field-proven heritage. Published IST case studies cover NASA Goddard spacecraft transport and lengthwise rail shock measurement, and EDR-3 recorders served as crash recorders in Indy cars in the late 1990s.
- Self-contained deployment. Built-in sensors, long battery life and nonvolatile memory let a recorder run without a laptop or external DAQ.
- Data that feeds the lab. DynaMax Suite produces PSDs and statistics that support shaker test profiles and environmental test level decisions.
- Environmental claims. IST states that the EDR-3C, EDR-4 and EDR-6DOF meet most MIL-STD-810F test methods, and it rates the EDR-5 enclosure to IP67.
- Buy or rent. Short programs can rent calibrated, pre-configured units instead of purchasing.
Local support from Vaughn Associates
Vaughn Associates represents IST in Alabama, Georgia, South Carolina, Tennessee, Mississippi, Louisiana, Florida and North Carolina. The fit is strong around Huntsville, where missile, space and aviation hardware moves between test sites, and across the Southeast automotive corridor and Gulf Coast shipbuilding community.
Our sales engineers help you decide what to measure and how: peak versus waveform recording, sensor ranges, triggers, mounting and deployment length. We coordinate purchase and rental quotes with IST, connect you with factory engineers for complex programs and follow up once the data is in. Recorders are typically purchased or rented directly from IST.
