Humans have made tremendous advancements in industrial machinery and equipment. The focus now is on making these machines and devices smart for improved productivity, accuracy, and ROI. The Internet of Things (IoT) is making this a reality, with sensors playing a crucial role. The industries that deploy industrial IoT solutions expect the data from the sensors to be accurate and well-founded from the automation standpoint.
Here are four reliable IoT sensors for development that are available in the market and are being deployed extensively for industrial automation projects.
Emerson Rosemount 5708 series 3D solid scanner
In the industries that deal with bulk solid and powder products, real-time measurement of mass/volume of the product in the inventory is a challenge. The 5708 series sensor uses acoustic waves to measure the level of the product in the inventory and sends the data to the software to update the inventory accordingly. Equipped with 3D visualization, the sensor is capable of measuring solids even with irregular shape.
Yokogawa DTSX3000 fibre optic sensor
The DTSX3000 is essentially a temperature sensing system. It is a long-range sensor with a very small power footprint. As they can run on solar power, these sensors can be deployed in remote areas without worrying about the power. Another specialty of the sensor is that the optical fibre attached to the sensors lets it measure temperature up to 50 km. This sensor is mostly deployed in oil and gas wells to measure the temperature and detect leaks.
Safran Colibrys TS1000T high-temperature inclinometer
The TS1000T is a micro-electro-mechanical accelerometer sensor that measures inclination or tilt. The specialty of this heavy-duty sensor is that it can measure inclinations at very high-temperature up to 175 degree Celsius. The sensor also boasts high stability under tremendous repetitive shocks. Its low power footprint can be imagined by the fact that it can work for 1000 hours at a stretch. Some of the most common applications of these sensors are in the drilling industry where measuring the tilt is crucial.
Yokogawa pH/oxidation reduction potential (ORP) FU24F sensor
In chemical industries where the acidity of the liquid solution needs to be measured at all times, pH/ORP sensors are widely used. These sensors measure voltage by creating a voltaic cell inside the solution and the pH or ORP is then calculated. FU24F stands out amongst these sensors as it prevents the desalting of the sensors by creating pressure compensation. The sensors thus, is unaffected by the external pressure in the liquid and its durability is enhanced.
Consistent innovation in techniques of measurement is needed to fully tap the potential of IoT. More efficient and durable sensors will be able to provide better data, both in terms of quality and quantity. Looking at the current trend, one can safely say that things are going in the right direction at the right speed.
