Voltage To PSI Formula:
| From: | To: |
The Voltage To PSI formula is a linear conversion equation used to convert electrical voltage readings to pressure measurements in pounds per square inch (PSI). This conversion is commonly used in pressure transducer and sensor applications.
The calculator uses the linear conversion formula:
Where:
Explanation: The formula represents a linear relationship where the slope determines how much the pressure changes per volt, and the offset accounts for the pressure reading at zero volts.
Details: Accurate voltage to PSI conversion is essential in industrial automation, process control, automotive systems, and HVAC applications where pressure monitoring is critical for system performance and safety.
Tips: Enter the slope value (psi/volt), measured voltage (volts), and offset value (psi). Ensure all values use consistent units for accurate results.
Q1: What is the typical slope value for pressure transducers?
A: Slope values vary by transducer model but typically range from 10-100 psi/volt for common industrial sensors.
Q2: How do I determine the offset value?
A: The offset is usually provided in the sensor datasheet or can be measured by recording the output voltage at zero pressure.
Q3: Can this formula be used for non-linear sensors?
A: No, this formula is specifically for linear transducers. Non-linear sensors require different conversion equations or lookup tables.
Q4: What if my sensor has a different output range?
A: The formula works for any linear sensor. Just ensure the slope and offset values match your specific sensor's characteristics.
Q5: How accurate is this conversion?
A: Accuracy depends on the precision of your slope and offset values, as well as the quality of your voltage measurement equipment.
