Drift means that the instrument slowly becomes less accurate. It means that there might be quality problems with the products or there might also incur serious safety issues.\n\nDeviation within the manufacturer\u2019s specifications, where the calibration certificate confirmation is required deviation out of specifications, where adjustments are needed to ensure that we can easily use the sensor again depending on the standards we want to use, we can differentiate between 3 similar cases: Verification, Adjustment, Calibration\n<h3>Pressure Measurement Devices<\/h3>\nThere is a multitude of pressure devices available for measuring different types of pressure or specialized for different applications. Some of them measure other variables as well.\n<ul>\n \t<li>pressure transmitters<\/li>\n \t<li>differential pressure transmitters<\/li>\n \t<li>pressure transducers<\/li>\n \t<li>pressure sensors<\/li>\n \t<li>pressure gauges<\/li>\n<\/ul>\nFollowing this, we can arrive at two scenarios:\n<h3>What is pressure measurement?<\/h3>\nIn short, pressure is a force exerted in an area. But how do we measure it will depend on what kind of pressure we want to measure. There are three kinds of pressure measurement and different devices to measure each: \u00a0<strong>absolute, gauge and differential pressure<\/strong>\n\n<h3>Pressure gauge calibration<\/h3>\nCalibration is the procedure of comparing a reference with a known error margin against a device (for example a pressure gauge) under test. If the device doesn\u2019t match the reference, then we adjust it to match, or at least come close, the desired measuring accuracy.\n\nThe reference measurement instrument must be more accurate than the pressure gauge to be calibrated, and it must also be traceable. To calibrate a pressure gauge, we will need to check the values throughout the entire measuring range, zero-point, intermediate values, and the full-scale value.\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-71ba1b9 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"71ba1b9\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-262cd2b\" data-id=\"262cd2b\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-53ce465 elementor-widget elementor-widget-image\" data-id=\"53ce465\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor - v3.20.0 - 26-03-2024 *\/\n.elementor-widget-image{text-align:center}.elementor-widget-image a{display:inline-block}.elementor-widget-image a img[src$=\".svg\"]{width:48px}.elementor-widget-image img{vertical-align:middle;display:inline-block}<\/style>\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"360\" height=\"269\" src=\"https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-02.jpg\" class=\"attachment-large size-large wp-image-2455\" alt=\"\" srcset=\"https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-02.jpg 360w, https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-02-300x224.jpg 300w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-9e53a9c\" data-id=\"9e53a9c\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-243175a elementor-widget elementor-widget-image\" data-id=\"243175a\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"360\" height=\"269\" src=\"https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-03.jpg\" class=\"attachment-large size-large wp-image-2456\" alt=\"\" srcset=\"https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-03.jpg 360w, https:\/\/www.odkint.com\/wp-content\/uploads\/2019\/04\/odk-news-03-300x224.jpg 300w\" sizes=\"(max-width: 360px) 100vw, 360px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-ef52958 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ef52958\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0adfd91\" data-id=\"0adfd91\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-cc5a66b text elementor-widget elementor-widget-text-editor\" data-id=\"cc5a66b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<blockquote><div class=\"blockquote-inner\"><div class=\"quote-text\">ODK International Services Limited products and services meet standards obtainable in major Oil companies to ensure that our clients receive the highest quality services provided in Nigeria and of the host community.<\/div><\/div><\/blockquote>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Incididunt ullabore et dolore magna aliqua.
