THE LOW DOWN ON PRESSURE TRANSDUCERS

Pressure transducers are versatile measurement devices designed to work in various environments and with different chemicals. They convert pressure measurements into an electrical signal that can easily be read by multiple control systems. They provide important information about the pressure within a tank or pipe, the weight of an object or the depth of a fluid.

✔️ Types of Pressure Transducers

• Gauge Pressure measures pressure relative to atmospheric pressure
• Vacuum Pressure measures pressure relative to atmospheric pressure
• Compound Pressure combines vacuum and gauge measurements
• Sealed Pressure measures pressure relative to a sealed reference point. Used for high-pressure measurements
• Absolute Pressure measures pressure relative to a perfect vacuum. Used for low-pressure ranges

👍 Choosing the right Pressure Transducer

1. Application Requirements
   • What pressure range will the transducer measure?
2. Environmental Conditions
   • Will the transducer be exposed to the elements, sheltered or submersed in liquid?
3. Accuracy and Range
   • What is the required precision and pressure range?
4. Compatibility
   • Will the transducer measure a corrosive or chemical substance?
5. Reliability and Maintenance
   • Is the transducer accessible for long-term maintenance and annual calibration?

🗝️ Key Features and Specs

• Accuracy ~ often shown as a percentage of the full-scale output
• Range ~ Minimum and maximum pressures the transducer can measure
• Response Time ~ How quickly can the transducer respond to changes in pressure?
• Durability ~ Resistance to harsh environments like temperature, humidity and corrosive substances
• Output Signal ~ The type of electrical signal put out by the transducer
• Connection Type ~ The physical and electrical connections like threaded or flanged.
