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.
Manufacturing and test environments can be very demanding, and most manufacturers need test equipment that is both accurate and reliable to meet increasing product throughput demands. To meet these demands, AMETEK Programmable Power has introduced the VTI EX1403 16-channel bridge and strain gauge instrument. The EX1403 sets the standard for stress and fatigue testing, delivering the highest performance measurements possible while keeping overall test hardware costs low and maximizing system uptime.
