Submersible Pressure Transducer for Liquid Level Measurement

Liquid material handling is one of many challenging things in the industrial process. The liquid materials are stored inside a tank and vessel, and since the container is water tight, it will be impossible to see the level of materials inside the container. That’s why level sensors are highly needed to provide the measurement. There are different types of level sensors used to measure the level of liquid materials inside a tank or vessel, with contact or non-contact sensors. What kind of level sensor you should use depends on the characteristics of the materials stored inside the tank.

Among many different types of level sensors, there is a submersible pressure transducer. Like other pressure transducers, this sensor works by converting applied pressure into an electric signal. The sensor has elastic material that will be deformed by applied pressure and electrical component to detect the deformity and sending electric signal translated to measurement reading. The difference is that a submersible pressure transducer is submerged inside a water tight container, and as its application is to measure level, it reads in feet or inch of liquid instead of psi pressure.

This type of level sensor is widely used in various industrial processes. Its popularity is in its versatility, allowing the sensor to be used to measure the level of any type of liquid as long as the temperature is within its working range. This type of level sensor is also cost efficient. Not only is the sensor inexpensive, but it also has low power consumption making it ideal for battery powered level sensors. No wonder submersible pressure transducers are widely used in waste liquids processing, and also for remote tank monitoring.

Even for low cost sensors, accurate reading is still a vital factor. Without accurate reading, any sensor is practically useless. This also works for submersible pressure transducers. It is important to only use high quality products with high reliability and durability. This is only possible when the sensors come from the leading supplier with top reputation.

More than just accurate readings, pressure transducers need to have complete features to make it a reliable control instrument for industrial processes. One of the crucial features is built in lightning protection. Delicate sensors are vulnerable to lightning strikes. Built in lightning protection ensures it is well protected. There is also a multiple cage option that is another great feature. The sensor instrument cage is much more durable and has a longer lifespan than the sensor. The option to replace the sensor while keeping the cage can save a lot of money. The field zero adjust is another important feature. As the sensor is submersible, it is difficult to zero adjust the sensor. Field zero adjust allows zero adjusting using simple magnets touched to the sensor cage. Last but not least, is chemical compatibility. The submersible pressure transducer must be compatible to different types of chemicals.
