Sensors & instrumentation that have a high frequency response measurement signal output or input.
These instruments are capable of rapidly updating displayed readings or recording data to capture measurements which require a fast dynamic response from the sensing technology and signal conditioning electronics.
Pressure instruments for recording data with very short time intervals via a PC. Analyse characteristics of changing pressures to millisecond resolution.
Display graphical plots on transfer data in tabulated form. 4-20mA, 5 volt or 10 volt output pressure sensors which have high frequency response amplifiers for monitoring rapidly changing pressures.
Digital readouts with quick update displays which refresh several times per second.
Capture the maximum reached pressure more accurately using a pressure gauge that refreshes its peak reading memory at a high frequency.

In test and research applications where one of the key measurement parameters is rapidly changing it is necessary to use instrumentation that can collect readings at a very high frequency.
For example if the position of an actuator arm is moving in and out at a frequency of 500 Hz, the position measurement device will need to measure in the order of x1000 Hz to provide enough readings to characterise how the position is changing during one full cycle of movement.
The frequency of response is typically limited by the sensing technology or the signal conditioning electronics, regardless of how fast either one is, the slowest one will always dictate the overall measurement response.
For example a very fast microprocessor combined with a slow reacting temperature probe, will provide lots of data points from the temperature probe. If the temperature changes faster than the response of the temperature probe then many of the data points will lag behind the actual temperatures at the time they were recorded or transmitted.
