How to reduce the measurement error of household appliance pressure gauge

Zhoushan Jiaerling Meter Co., Ltd. is committed to providing high-precision household appliance pressure gauges, using sensor technology to ensure that its core components have excellent measurement capabilities. As a key component of the measurement system, the accuracy of the sensor directly determines the reliability of the measurement results. The company has undergone rigorous screening and testing in the selection of sensors to ensure that they can still maintain a high level of measurement accuracy in a complex environment with a wide temperature range and high pressure changes. In addition, Zhoushan Jiaerling implements a regular calibration procedure, using high-precision calibration equipment to accurately calibrate the pressure gauge to ensure the consistency of its readings with the actual pressure value, thereby effectively reducing the error caused by sensor drift or aging.
In terms of manufacturing technology, Zhoushan Jiaerling focuses on optimizing the design and strives to reduce the errors that may be introduced in the manufacturing process in every link. From the selection of materials to the control of processing accuracy, each step has been carefully designed. For example, materials with low expansion coefficients are selected to reduce the impact of temperature changes on measurement accuracy; through precision machining technology, the assembly accuracy between various components is ensured, thereby reducing the measurement deviation caused by assembly errors. In addition, the company has introduced advanced automated production lines, using robots and intelligent equipment to improve processing accuracy and production efficiency, and further reduce the impact of human factors on product quality.
Environmental factors also have an important impact on the measurement accuracy of pressure gauges, including temperature, humidity and vibration. Zhoushan Jiaerling fully considered these environmental factors during the product design stage, and effectively reduced the interference of environmental changes on the measurement results by adopting temperature compensation technology and sealing structure design. At the same time, the user guide clearly points out the working environment conditions, and recommends that users use the product within a specific temperature and humidity range and avoid operating in an environment with severe vibration to ensure the accuracy and reliability of the measurement results.

What are the precautions for installation and commissioning of household appliance pressure gauges

When installing and commissioning pressure gauges, adequate preparation is essential. First of all, the selection of instruments should be based on the specific needs of household appliances. Zhoushan Jiaerling Meter Co., Ltd. provides pressure gauges of various specifications and accuracies to meet the measurement requirements of different industries and application scenarios. During the selection process, users need to carefully consider key factors such as the maximum working pressure, measurement range, accuracy level, and use environment of the equipment to ensure that the selected instrument can operate stably under specific conditions.
Users need to conduct a comprehensive assessment of the installation environment to ensure that the temperature, humidity and vibration conditions of the environment meet the use requirements of the pressure gauge. The pressure gauges of Zhoushan Jiaerling Meter Co., Ltd. are usually suitable for an ambient temperature range of -25℃ to 55℃. Exceeding this range may lead to increased measurement errors or damage to the instrument. Therefore, it is crucial to ensure the suitability of environmental conditions.
In terms of tool preparation, users need to prepare the tools required for installation, including wrenches, screwdrivers, sealing washers, etc. Reasonable selection and use of tools can effectively avoid damage to the instrument and ensure the smooth progress of the installation process.
In the actual installation process, there are several key precautions that need to be strictly followed. First, the pressure gauge should be installed perpendicular to the horizontal plane to ensure the accuracy of the measurement results and avoid measurement errors caused by tilted or horizontal installation. In addition, the location selection of the pressure tapping port has a significant impact on the accuracy of the measurement results. Avoid installing the pressure tapping port in the bend, bifurcation and vortex formation area of ​​the pipeline. When there are protruding objects (such as temperature measuring elements) in the pipeline, the pressure tapping port should be set on its upstream side. At the same time, a certain distance should be maintained between the pressure tapping port and the regulating valve to reduce the impact of pressure fluctuations on the measurement.
The laying of the connecting conduit also needs to be arranged reasonably to ensure that the horizontal section has an appropriate slope to facilitate the removal of condensed liquid or gas. For gaseous media, the conduit should be tilted downward toward the pressure tapping port; for liquid media, the conduit should be tilted toward the pressure measuring instrument. The sealing check is also an important part of the installation process. Users need to carefully check the integrity of components such as instrument joints and sealing gaskets to ensure the sealing after installation. The pressure gauges provided by Zhoushan Jiaerling Meter Co., Ltd. are usually equipped with high-quality sealing gaskets to ensure a good seal of the measurement system.
After the installation is completed, commissioning and calibration are necessary steps to ensure the normal operation of the pressure gauge. The preliminary inspection should include an inspection of the appearance of the pressure gauge to ensure that the pointer moves freely and can be zeroed. When using a calibrator to calibrate the pressure gauge, the calibrator should be placed on a workbench that is easy to operate and kept horizontal. The working environment temperature of the calibrator should meet the requirements to avoid corrosive gases in the surrounding air.
The calibration process should be carried out in accordance with the specifications, gradually increasing and decreasing the pressure, and recording the readings of the pressure gauge at different pressure points. Zhoushan Jiaerling Meter Co., Ltd. recommends taking five measurement points at 0%, 25%, 50%, 75%, and 100% of the pressure range during calibration to ensure the accuracy of the calibration results. After the calibration is completed, the basic error, return error, variation, and error caused by tapping the case of the pressure gauge should be analyzed to determine the qualification of the pressure gauge. If it is found to be unqualified, it should be adjusted or replaced in time.
