The first idea you get about hydraulic pressure transducer is that it is a subset of the pressure transducer. The main work of it is to measure and take a sample record of the pressure in the system. It changes or usually coverts any kind of energy in any forms into an electronic signal.
All pressure transducers require a source, and it can be an electrical source. But it consumes very less amount of voltage may be 10V, while the output is in thousands and it is sensitive, that is even a slight change may cause the resistance to change and would also change in the output of the hydraulic pressure transducer.
Working Principle Of Hydraulic Pressure Transducer:
The working principle of the hydraulic pressure transducer is a difficult one. It may seem like a very difficult concept to grasp but it is very easy. It measures the pressure of the fluid. The fluid indicates or exerts pressure on the surface when it comes in contact. Not only controlling the pressure but hydraulic pressure transducers are used in other applications as well. They are used to control and monitor many things like flow, speed, pump system and level or attitude. It has a force collector in the form of a flexible diaphragm. It usually deforms when pressure is applied and the transduction element that is present turns it into an electrical signal. The process optimizes according to the requirement of the process and how it is being measured. You can use a programmable logic controller or an automation controller to monitor the digital signals and you can take necessary actions. In this case, you can use hydraulic pressure transducer which will work as the transmitter. But when you measure the output of a hydraulic pressure transducer you should accept the signals generated by the transducer, and then you must measure the distance covered by those signals to take a perfect measurement.
Finding the Right Transducer for the Right Application:
- Protection from the Hazardous Environment: There are different types of transducers available in the market and you must choose the correct one. You must install a hydraulic pressure transducer with a suitable power supply. You could do this by installing them in explosion-proof housing or using safe designs that are guaranteed. Apart from that, you must maintain all guidelines provided by the manufacturer to ensure the best results.
- Pressure: When selecting a hydraulic pressure transducer, keeping the pressure range in mind is very important and crucial. It is one factor that plays a very important role in the well functioning of the transducer. Two things you should definitely keep in mind are the instrument’s accuracy and its capability of taking overpressure. The accuracy should be low so that there is not even a minimum error. You should be able to isolate and make sure that you are able to pressure test and start up the instrument without any failure and in isolation if needed.
- Corrosion Protection: It is important that you consider corrosive liquid or corrosive materials coming in contact. This could be prevented if you carefully install your hydraulic pressure transducer by selecting corrosion-resistant materials and coatings. If necessary, you could also use chemical seals to provide it with more guard. The housing should be taken care of as well. It should meet both the electrical area classification as well as all the corrosion protection requirements.
When you are working in a high-pressure environment, you could divide or isolate the pressure instrument and take it to an air-conditioned area. Isolation could be done with the help of loop seals, chemicals seals, and others.
