Pressure transducers are used to convert one form of energy into another. They are mostly used in industry to check the pressure exerted by machinery and convert it into an electrical signal. These measurements are then recorded on to data loggers for further use. Pressure transducers are further classified into two categories as below.
Force collectors and non force collectors
Force collectors use bellows, diaphragms or pistons to exert pressure. On the other hand, strain gauge transducers, piezoelectric transducers and thermal and resonant transducers fall into the category of non force collectors as they do not use this equipment.
Performance
The performance of these transducers depend upon the range, over-range capability, burst pressure, full scale output, zero unbalance and resolution. Range refers to the accuracy of pressure measured by the pressure transducer. The over range capability is the maximum pressure exerted on the transducer without changing its performance. Burst pressure is the expected level of leakage from the transducer. Full scale output, also known as FSO, refers to the difference in the output signal. Zero unbalance is the output given by the transducer due to no pressure being exerted. Resolution refers to the minutest change in the pressure detected in the output of the transducer.
Different types of pressure transducers like gauge pressure sensors, absolute pressure, differential pressure are used to measure different types of pressure in various industries. Pressure transducers are an easy way to measure the pressure and record it in the form of data which would otherwise have been impossible.
