Remote Telemetry / Wireless
Low Power Pressure Transducers For Remote Telemetry/Battery Applications – IIOT
Sensors such as pressure transducers play an important role in measuring and collecting data. The data collected enables users to monitor their equipment and make more informed decisions regarding their application. The pressure gauge was the primary source of data gathering in the past. Users would need to drive to the application site, manually read the gauge, and report back the reading. This process would not only cost time but also money, both in inefficient equipment operations and unnecessary maintenance. The advancement of pressure sensors and transducers has greatly improved the efficiency of collecting and interpreting data in remote applications. When paired with wireless telemetry systems, low power pressure transducers can continuously collect pressure readings and send the readings to the cloud which can be accessed by users in any location.
There are a few popular uses of pressure transducers in wireless telemetry systems. Industrial businesses are typically looking to: monitor inventory, measure for maintenance, and monitor for safety and control.
Inventory management is critical in remote applications as it enables users to actively monitor levels without having to regularly send an operator to the field for updates. There are different types of liquid and gas storage tanks where monitoring can be beneficial. Pressure transducers can help prevent equipment from going idle by monitoring the level of fuel in a tank such that the delivery company knows when the tank is getting low and a refuel is required. Other tanks such as chemical injection storage tanks can use pressure transducers either internally or externally for level monitoring or dosing the liquid into the system. Sealed storage tanks typically use differential pressure transducers to measure the difference in pressure from the bottom of the tank to the top, resulting in a continuous level measurement.
When systems can cost anywhere from thousands to millions of dollars, maintenance of the most expensive components is crucial. Many compressor stations both upstream and downstream use pressure transducers to ensure the engines are running at peak performance. If changes in measurement are detected, the system can be shut down for safety reasons and then checked. If a trend of pressure shows increasing or decreasing, it can also be a sign that changes to engine or filters are required. Having instant access to this information makes scheduling maintenance much easier and more cost effective.
Using high quality pressure transducers to continuously measure application pressure ensures the safety and control of remote equipment. Users are able to set up programs and codes for equipment to react to different pressure events that the pressure transducer experiences. If, for example, a pressure transducer experiences an increase in system pressure above a pre-defined safety limit, an event can be triggered to either shut the entire system down or open a safety valve to release pressure. An alarm can also be triggered to alert an operator anywhere in the world that a safety event has occurred and a maintenance team should be sent out to evaluate.
