Hello, i'm 4515do-ds5ai002dp sensor department, zhang。
4515do-ds5ai002dp differential sensors measure the differential pressure between two pressures, one connected to each side of the sensor. The differential sensor is used to measure many properties, such as pressure relief for oil filters or air filters, fluid levels (by comparing pressure above and below fluids) or flow (by measuring pressure change for limitrs). Technically, most pressure sensors are actually differential sensors. For example, a surface sensor is only a differential sensor open to the atmosphere on one side。
4515do-ds5ai002dp differential sensors provide the difference between two pressure sources through two ports, allowing the required pressure input to be provided to the equipment to measure readings. The differential sensor industry is expected to witness growth due to the high accuracy and resolution of respiratory flow measurements。
4515do-ds5ai002dp differential sensors are a typical self-balancing test instrument that uses negative feedback to overcome the effects of adverse factors such as component materials, process processes, etc. The differential sensor is applied to prevent the medium in the pipe from entering the sensor directly, and the cavity pipe connection between the pressure-sensitive film and the sensor is filled with fluids. The differential sensor is used to measure the liquid level, flow and pressure of liquids, gases or vapours and converts them to digital signal output。
4515do-ds5ai002dp differential sensors must consider the following parameters:
Type of pressure measure: the type of pressure is primarily a pressure pressure, stress, differential pressure, etc.; the pressure is based on atmospheric pressure, which is less than or greater than atmospheric pressure; the pressure is based on positive pressure zero, which is higher than positive pressure zero; the pressure difference is the difference between the two pressures。
2. Accuracy level: the sensor's measurement error is classified by the accuracy level, and selection is made in the actual use on the basis of the need to measure the error and in accordance with applicable economic principles。
3. System overload: the system overload should be smaller than the sensor overload maintenance limit, otherwise it may affect the life of the commodity or damage it。
Measurement range: generally selected on the basis of actual measured pressure of 80 per cent of the measured range。
Working temperature scale: the temperature of the measured medium shall be maintained within the temperature range in which the differential sensor is able to function, the error will become large if the temperature exceeds the range in which it is used and the instrument's useful life will be corresponding, and the temperature effects will be measured and offset during the production of the differential sensor to ensure that the measurement error that occurs when the commodity is affected by the temperature is within the precision requirements. At higher temperatures, it is possible to think about hot, high-temperature pressure sensors or to adopt complementary cooling methods such as condensers, radiators, etc。
6. Measuring the compatibility of media with touch raw materials: in certain application locations, because of the corrosive nature of measuring media, it is necessary to select information compatible with the mass media or special process processing to ensure that 4525do-ds3bs015ds differential pressure sensors are not damaged。
