A pressure switch can help ensure safe, reliable measurements for an application, but only if you fully understand the physics of its mechanics and the various nuances such as the setpoint, reset point and deadband. But what does deadband mean and how does it apply to a pressure switch? This article will explain the meaning of deadband and how it works so you can help ensure continued accuracy for your application.

Your pressure sensors are an important part of your application, ensuring accurate and reliable measurements and the safety of your process and its operators. To keep your processes working properly, recalibration of your sensors may be necessary over time. Sensors can degrade over time as components are exposed to wear, temperature and cycling. This can lead to a loss of stability and drift in the output signal of the sensor away from its published specification. Using sensors that cannot be recalibrated would require the replacement of the sensor once it drifted outside of its specifications and its output signal was no longer reliable. This could cause your critical application to shut down temporarily until the sensor can be replaced. A sensor that can be recalibrated will not only prolong the sensor’s life but will have your process back up and running in no time at all. This article will discuss zero and span adjustability and the benefits it can provide to your process.

Pressure switches are important components in your application and accurate and reliable pressure measurements are key to ensuring a safe and efficient process. An incorrectly specified pressure switch could lead to actuation errors, damaged equipment, worker injury or other dangerous issues.

Everyone’s application is different, requiring a wide range of instrumentation for measuring and monitoring. Luckily, there’s a product available for almost everyone now, especially in the pressure switches market. But how do you know what pressure switch is right for your process?
