Sensor Terminology NI

· For example, a given pressure sensor may have a range of 400 to +400 mm Hg. Alternatively, the positive and negative ranges often are unequal. For example, a certain medical blood pressure transducer is specified to have a minimum (vacuum) limit of 50 mm Hg (Y min in Figure 1) and a maximum (pressure) limit of +450 mm Hg (Y max in Figure 1). This specification is common, incidentally, and is one reason doctors and nurses sometimes destroy blood pressure sensors …

Pressure sensors: The design engineer’s guide

Pressure sensors vary widely in their construction, due to the range of applications for the components. Just one example is their use in consumer equipment such as smartphones, often to aid navigation or other more specialized measurement apps. Typically, these are barometric pressure sensors, designed to detect changes in atmospheric pressure. Throughout industrial and commercial scenarios ...

· For example, suppose a pressure of exactly 150 mm Hg is applied to a sensor. Even if the applied pressure never changes, the output values from the sensor will vary considerably. Some subtle problems arise in the matter of precision when the true value and the sensor''s mean value are not within a certain distance of each other (, the 1s range of the normal distribution curve).

Piezo Sensor Applications Variohm

· Piezo Sensor Applications. Piezo sensors are used within many sensors and devices. They are used to convert a physical parameter; for example acceleration or pressure, into an electrical signal. Piezo sensors are used to measure the change in pressure, acceleration or strain by converting them into electrical charge.

What is a strain gauge? | Omega Engineering

A Strain gauge (sometimes refered to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result. Stress is defined as the object''s internal resisting forces, and strain is ...

What is a sensor? Quora

A sensor is basically a device which detects and converts your signal of interest into a measurable or observable quantity (mostly an electrical signal). Say for example, a pressure sensor detects pressure and converts it into an electrical output which can be further processed for actuation or to be displayed.

Pressure sensor Wikipedia

A pressure sensor is a device for pressure measurement of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.
