The SDP31-500PA is a pressure transducer with the highest accuracy, suitable for a variety of industrialgases, oils, and liquids. It has a pressure range of -14.696 to 21.497 psi and is the most accurate sensor in its price range. The SDP31-500PA is an ideal choice for applications that require an accurate measurement of high pressure and absolute pressure, such as laboratory testing, scientific research, and aircraft engines.

The working principle of the SDP31-500PA is based on piezoresistive pressure measurement technology. This type of measurement uses an array of resistors, known as a strain gauge, which are embedded into the sensing membrane. As the applied pressure changes, the strain gauges change their resistance, thus providing an output signal proportional to the pressure. The output signal is typically 4–20mA and is sent to a readout device such as a display.

To ensure high accuracy and repeatability, the SDP31-500PA is temperature-compensated. The temperature compensation is done by a built-in temperature sensor which monitors the sensor temperature and adjusts the readings accordingly.This ensures that the sensor accurately measures applied pressure values under varying temperature conditions.

Another advantage of the SDP31-500PA pressure transducer is its robust construction. The housing is made of stainless steel, which offers superior corrosion protection. Additionally, the membrane is made of a special material which prevents damage to the sensor due to high pressure applications. This makes it ideal for use in harsh environments where high pressure and temperature changes are common.

The SDP31-500PA is ideal for applications that require high accuracy and repeatability. It is also an excellent choice for applications that require robust construction and reliable performance in extreme environments. It is an ideal choice for applications in laboratory testing, scientific research, and aircraft engines, as well as any other application that requires reliable measurement of high pressure and absolute pressure.
