The phrase "at a certain range" is correct and usable in written English.
It can be used when discussing limits, distances, or intervals in various contexts, such as measurements, statistics, or performance.
Example: "The device operates effectively at a certain range, ensuring optimal performance in various conditions."
Alternatives: "within a specific range" or "at a defined range".
We look for ways to keep our team together at a certain range of pay and we have to change some guys, a position here, a position there.
All soil specimens had a hydraulic conductivity of < 1 × 10−7 cm/s at a certain range of moulding water content.
The dielectric loss ɛ″ demonstrates a deviation from frequency temperature superposition at a certain range of frequency, with the deviation increasing with increasing density of the side chains.
Only when the NVCL content was confined at a certain range, it would appear obvious thermo-thickening phenomenon above the critical associative temperature (Tass).
They are explained further in our answer to What are RA and DEC? From a given location on Earth you can only see stars at a certain range of declinations.
"Carl is effective at a certain range," said Larouche.
Most stochastic processes can be approximated by σ y ∝τ k, at least over a certain range of τ.
Large existing solid biomass power plants, meanwhile, could also run more flexibly at least in a certain range of power, as soon as they are refinanced.
This approach was chosen because the significance of the interactions between the variables would have been lost if the experiments were carried out using the classic methods of varying the level of one parameter at a time over a certain range, while holding constant the rest of the tested variables.
The finite element (FE) method is suitable for low frequency analysis and the statistical energy analysis (SEA) for high frequency analysis, but the vibro-acoustic coupling analysis at middle frequency, especially with a certain range of uncertainty system, requires some new methods.
Thus it is reasonable that only a small part of the constituent signals will be simultaneously active at a given location and a certain range of frequency band.
