Product Description

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 speed.

For example if the hydraulic pressure in an actuator arm is increasing and decreasing at a frequency of 5 Hz, the pressure measurement device will need to measure in the order of x100 Hz to provide enough readings to characterise how the position is changing during one full cycle of movement.

The speed 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 quick microprocessor combined with a slow reacting pressure sensor, will provide lots of data points from the pressure sensor. If the pressure changes faster than the response of the pressure sensor then many of the data points will lag behind the actual pressures at the time they were recorded or transmitted.

Pressure sensors are measurement devices for detecting variations in pressure of liquids or gases. Typically a pressure sensor is made of two subcomponents, an electromechanical assembly on the frontend, and a signal conditioning module on the backend.

The frontend of the pressure sensor is connected directly via a thread or clamped seal to a pipe or vessel containing the liquid or gas to be measured. The pressure generated by the liquid or gas will apply a force to a sensitive exposed surface area within the electromechanical assembly which produces a physical change to the material, such as a deformation. This physical change is translated into an electrical change by smaller elements incorporated into the sensitive part of the assembly, typically on the reverse side of the surface in contact with the liquid or gas.

Since there are many different types of electromechanical technology used to measure pressure, producing very different electrical characteristics, it is necessary to add on a signal conditioning module to rationalise the electrical signal and convert it to one which is a commonly used standard within a particular industry or application.
