Do you have a Pressure Transducer installed on a machine that operates on a 0-5 V range, but you're unsure of its pressure range? If you're looking to determine the pressure range of the transducer, one method is to apply a known pressure, such as 100 psi, measure the corresponding voltage output, then repeat the process at a different pressure, like 200 psi. By analyzing the data points, you may be able to establish a linear equation for the transducer. However, there may be other procedures required for accurate calibration. It's important to note that without knowing the pressure range, it can be challenging to accurately interpret the transducer's readings.
Typically, these devices follow a linear format. To confirm, refer to their datasheet or manual. Your image does not display a 0-5 V output; rather, it shows a range of 4-20 mA over a seemingly 0-100 psig range. Ensure accuracy by consulting the product documentation.
JeremyM explained that these devices typically operate in a linear manner, so it's advisable to refer to the data sheet or manual for verification. The image provided does not indicate a 0-5 V output; instead, it seems to operate within a range of 4-20 mA over 0-100 psig. Keep in mind that the photograph is merely an illustration and does not represent the actual product in use, which has a 5 V power source without any identifying stickers, serial numbers, or data.

adrirock1141 pointed out that the photograph is merely an illustration, and the source voltage is 5 V with no labels, serial numbers, or data. To test the linearity of the sensor's output, it is recommended to increase testing points throughout the input range, including the endpoints. Adding around 10 more points should provide a clearer indication of linearity.
Linear transmitters, such as the one being discussed, typically have a specific range. By conducting just one test, you can determine the transmitter's full range. If we assume that the transmitter does not measure bipolar pressure (ranging from vacuum to gauge pressure, with -15 to +X PSI where 0 PSI does not equate to 0Vdc output), then applying 50PSI will represent different percentages of its potential range: - 100% of 0-50 PSI - 50% of 0-100 PSI - 25% of 0-200 PSI - 16.7% of 0-300 PSI - 10% of 0-500 PSI This information is crucial for accurately interpreting the transmitter's readings and understanding its capabilities.
If you're looking to calibrate an analog device or a pressure transducer, try searching for "calibrating an analog device" or "calibrate pressure transducer" on a search engine. You can also find more information by searching for "multiply by unity" within this forum. Keep in mind that 0PSI can correspond to either 0V or 1V.
That's an excellent point you brought up. It's also worth mentioning that the manufacturer's data sheet is often a good starting point to check for the Pressure Transducer's range. Sometimes, it can help avoid the manual testing process. But if the data sheet isn't available, then your approach seems like a reasonable alternative. Some transducers also have pressure range marked on them so it's good to check for any marking or label on the machine. But regardless, ensuring proper calibration is still critical for any Pressure measurement to be accurate.

Answer: Answer: One method is to apply known pressures, measure the corresponding voltage outputs, and analyze the data points to establish a linear equation for the transducer. Additional calibration procedures may be needed for accuracy.
Answer: Answer: Without knowing the pressure range, it can be difficult to accurately interpret the transducer's readings, potentially leading to inaccuracies in pressure measurements.
Answer: Answer: Testing the transducer at multiple pressure points, such as 100 psi and 200 psi, can help in establishing a more accurate pressure range by analyzing the relationship between pressure and voltage output.
