Hydraulic Pressure Sensors

Hydraulic pressure sensors, often known as transducers, convert pressure measurements into an analog electrical output signal. These types of pressure sensors are ideal for use in a range of industrial applications that utilise hydraulics.

How do hydraulic pressure sensors work?

Just like other transducers, hydraulic pressure sensors utilise an electrical input in order to work successfully. The input voltage of the transducer is commonly under 10 volts, however, it may vary depending on the type of sensor. In comparison, outputs are often in the hundreds of thousandths of volts. A difference in pressure causes the electrical circuit's transducer resistance to be altered. This in turn causes a change to the output voltage. A hydraulic pressure sensor's output signal can be used in systems that need digital signals to work with the simple addition of an analog to digital converter (ADC).

Types of hydraulic pressure sensors

Stain gauge - Commonly the impedance or electrical resistance of a strain gauge will be changed when a strain gauge element is compressed or stretched.

Thick/thin transducer - In a thick/thin type of film transducer, the sensor equipment features a titanium nitride film to expose the circuit with piezoelectric (an electric voltage) sensitivity to pressure.

vary but is typically under 10 volts, while the output is usually in the hundreds of thousandths of volts. A change in the system's pressure causes a change in the transducer's resistance on the electrical circuit used and then results in a change to the output voltage. A hydraulic pressure sensor's output signal can be used in systems that need digital signals to work with the simple addition of an analog to digital converter (ADC).

Types of hydraulic pressure sensors

Stain gauge - Stain gauge transducers use the mechanical deformation under pressure of strain-sensitive variable resistors, which may be integrated into measurement circuits.

Thick/thin transducer - In a thick/thin film transducer, a titanium nitride film is applied to the sensor equipment to expose the circuit with piezoelectric (an electric voltage) sensitivity to pressure.
