Pressure Sensors

The PPT0300DFF2VB (PPT) is a rugged, stainless steel pressure transducer designed for various industrial applications. It is used to measure and monitor changes in pressure in many liquid and gas systems, including hydraulic pressure, air pressure, water pressure, and even cryogenic gas systems. The 0.3 percent full-scale accuracy allows it to achieve high accuracy readings even under extreme conditions or when controlling a system with consistently fluctuating pressure. This makes it applicable for a wide variety of industrial applications.

The device can be mounted in either standing (upright) or pressure ports. It is ideal for a variety of environments, from harsh ones like those that are common in industrial settings to benign ones like those found in laboratories. It is available with a variety of outputs, including 5 Vdc, 4 mA to 20 mA, 0 to 10 Vdc, 4 to 20 mA or 0 to 5 Vdc. PPT also offers optional features including vibration and shock protection, reverse polarity protection, and a stainless steel sealed pressure port.

Transducers

The PPT0300DFF2VB is a pressure transducer that harnesses the principle of piezoresistance. This means that it is capable of detecting changes in pressure by measuring the mechanical strain or deformation of a mechanism that is sensitive to the pressure. In this case, the deformation is caused by the pressure, which is then transferred to an integrated strain gauge. This gauge then converts the mechanical strain into an electrical signal that reflects the pressure.

The strain gauge is then connected to a Wheatstone bridge, which includes four resistors. As the pressure causes a change in the resistance of the strain gauge, a difference in voltage is detected between two points of the bridge. This voltage is then converted into a usable signal that is proportional to the pressure that is being detected. The signal can then be fed into an electronic control instrument, such as a controller or measuring device.

The PPT0300DFF2VB pressure transducer is suitable for a variety of applications including those in the industrial field. It is easy to install, as it requires no special calibration. Its stainless steel housing ensures that it is resistant to corrosion, vibration, and extreme temperatures. This makes it an ideal choice for many applications, as it can provide reliable readings even under extreme conditions.
