Also known as a pressure transducer, it is essentially a sensor made of a pressure-sensitive shell (steel, silicon, or other material) that measures the pressure inside a machine and converts this pressure to an electronic signal that can then be read on a display.<\/p>\n<p>Pressure transmitters are used in a wide range of industrial sectors: the readings they provide alert plant operators before an incident occurs. However, over time, the performance of pressure transmitters decreases. If operators do not calibrate pressure transmitter instruments regularly, they can give inaccurate readings.<\/p>\n<h2 id=\"h-what-is-the-importance-of-transmitter-calibrations\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_the_Importance_of_Transmitter_Calibrations\"><\/span><span id=\"What_Is_the_Importance_of_Transmitter_Calibrations\" class=\"ez-toc-section\"><\/span>What Is the Importance of Transmitter Calibrations?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Calibration is the process of comparing a known value with the measurement result of the pressure transmitter; as such, it ensures that the readings of the measuring device are accurate.<\/p>\n<p>The outcomes of inaccurate measurements of a pressure transmitter will vary, but in general, drift in readings can have a detrimental effect on productivity and process efficiency.<\/p>\n<p>Additionally, it\u2019s important to calibrate pressure transmitter devices to:<\/p>\n<p><strong>Maintain Safety:<\/strong><\/p>\n<p>Depending on the application, drift between the accurate and current readings can be dangerous and potentially life-threatening. Calibration helps maintain accuracy and thus provides greater safety, especially in process environments. Because calibrated products and components perform as expected, they are also safe to use.<\/p>\n<p><strong>Identify Errors:<\/strong><\/p>\n<p>Although high-quality transmitters are designed for long-term performance, reading errors can occur at any time. Transmitter performance may decrease due to operational stress or other factors in the operating environment. Periodical calibration helps identify these errors.<\/p>\n<p><strong>Avoid Damage:<\/strong><\/p>\n<p>Machine downtime is undesirable in industry as it leads to inactivity, wasted resources, and revenue loss. By regularly calibrating transmitters, plant operators can reduce or avoid machine downtime and maximize productivity.<\/p>\n<p><strong>Conform to Regulations:<\/strong><\/p>\n<p>Organizations must follow specific regulatory standards to be able to operate. Regulations often exist to ensure reliable, consistent quality to customers. Calibration is one step toward meeting such standards.<\/p>\n<h2 id=\"h-why-do-technicians-calibrate-at-the-bench\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Do_Technicians_Calibrate_at_the_Bench\"><\/span><span id=\"Why_Do_Technicians_Calibrate_at_the_Bench\" class=\"ez-toc-section\"><\/span>Why Do Technicians Calibrate at the Bench?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The main reason behind calibrating at the bench is that it allows for working effectively and accurately.
