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.
For many test applications, measuring the temperature is a necessity. For example, when testing an aircraft engine, you may need to measure manifold temperature or the exhaust gas temperature. To help you take those measurements, VTI Instruments offers a number of options, including the EX1000A series of precision voltage measurement instruments and the RX1032 rugged thermocouple measurement system.
Thermocouples are arguably the most common type of temperature sensor, although you can also use resistance temperature detectors (RTDs), or thermistors. The EX1000A series supports all three types of sensors, while the RX1032 supports only thermocouples.
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.
