How to Select a Pressure Transducer/Pressure Sensor
Prior to purchasing a pressure sensor, there are a few factors you should think about. These may range from the amount of pressure the sensor needs to measure to the environment in which the sensor will be used. Once you’ve determined your specific needs and the requirements for your pressure sensor, you can find the right sensors for your company’s needs, or determine that a customized solution would be a better option
We’ve divided these factors into five main categories for you to keep in mind as you search for the right pressure sensor for your application.
1. Performance Deliberations for Pressure Sensors
Once you start your hunt for the perfect pressure transducer, the most vital factor is whether it will perform at the level you require. You need to find a product that has the capabilities to handle your specific application. To do this, you will need to determine:
- The maximum pressure you intend to measure
- The pressure reference needed by your application (including differential, vacuum, true gage, sealed gage, absolute etc.)
- The engineering units you require (psi, bar, mbar, Pascal, atmospheres, inches of mercury, feet of water) or if the units need to be customer-specified
- Accuracy, both static and thermal
- Pressure conditions the sensor will encounter, including overpressure, burst pressure, dynamic loading, fatigue loading and vacuum range
2. Mechanical Considerations for Pressure Sensors
Consider the following mechanical aspects for your pressure transducer:
- Physical constraints (size, orientation, location)
- Type of media (hydrogen, abrasive, corrosive, biological, radioactive)
- Temperature of media
- Pressure port and process connection
- Configuration and other requirements, such as small diameter, flush diaphragm, secondary containment or explosion-proof, among others
3. Electrical Considerations for Pressure Sensors
Consider the following mechanical aspects for your pressure transducer:
- Electrical termination
- Electrical output from the sensor – is it analog, digital, or a combination?
- External zero and span potentiometers
- Din rail mount or in-line signal conditioning for mV/V units
4. Environmental Considerations for Pressure Sensors
The environment where the pressure sensor operates plays a key role in the selection of the sensor. In order to receive accurate readings, here are a few things you should keep in mind when choosing your sensor:
- Operating temperature range – if not compensated correctly, it can change the readings drastically
- Compensated temperature range
- Electromagnetic and radio frequency interference (emi/rfi) conditions
- Is an ingress protection (ip) or national electrical manufacturing association (nema) rating required?
- Will the sensor be in a hazardous environment?
- Is the sensor explosion-proof or intrinsically safe?
- Will it be used outdoors? how will it endure animals and other critters, dirt or dust, elements, or even extreme temperature?
- Is it submersible (for salt water or fresh water)? what are the depth parameters?
5. Special Requirements for Pressure Sensors
Some systems may have specific requirements for pressure transducers such as:
- Collaboration requirements
- Special approvals/certifications/testing or cleaning
- Special labeling requirements
- Frequency response
- Shock and vibration resistance
- Serviceability
