Measuring Temperature with RTDs

Posted by Chris Gibson on Nov 18, 2019 12:00:00 PM

Although thermocouples are the most commonly used temperature sensor in test applications, a close second is the resistance-temperature detector, or RTD. RTDs operate on the principle that the resistivity of a metal is proportional to its temperature. The higher the temperature, the higher the resistivity.

Solving Jet Engine Test Problems Using Ruggedized Equipment

Posted by Jon Semancik on Nov 1, 2018 12:00:00 PM

A jet engine is the very definition of “mission-critical.” A critical failure could cause a serious accident that endangers hundreds of lives. To prevent this from happening, manufacturers perform extensive testing on jet engine components, systems, and manufacturing processes.

Jet engine tests involve subjecting the unit under test to extreme temperatures, jets of water, simulated hail, severe vibration, and other harsh conditions. Sometimes test engineers even slam chicken carcasses against engines to simulate bird strikes. These tests can be very costly and take years to develop. Engineers must measure many different parameters during these tests, including temperature, flow, pressure, rotation, strain, and vibration.

Time Stamping for Multi-Channel Data Acquisition Systems

Posted by AMETEK Customer Service on Mar 26, 2018 2:19:59 PM

For multi-channel data acquisition systems, getting the correct readings in the correct timed order is crucial. System designers have two options for acquiring data in a deterministic fashion. They can use a real-time operating system (RTOS), that has a known buffer delay/ processing order or acquire data with a time-stamp for every sample and use precise hardware triggers and an accurate clock.
