Pressure Sensors
The terms pressure sensors, pressure transducers and pressure transmitters are often used interchangeably due to their common function of pressure measurement. Both pressure transducers and pressure transmitters require a pressure sensor to operate, as the sensor is the primary element that detects pressure. Emerson's Paine and Rosemount products integrate advanced pressure sensors for high precision and reliability in demanding industrial environments.
Frequently Asked Questions
If you have additional questions related to pressure sensors and pressure transducers, please contact us.
A pressure sensor is a device that detects pressure and converts it into a signal that can be read and used. Oftentimes, a pressure sensor will convert the pressure reading into a voltage, resistance, or capacitance which then can be used by a pressure transmitter to output in a more common format. Pressure sensors or key components of pressure transmitters.
A pressure transducer is a device that takes a signal from a pressure sensor and converts it to a readable signal such as voltage. In general pressure transducers are very similar to pressure transmitters but often much simpler devices.
While the terms are often used interchangeably, a pressure sensor broadly refers to any device that detects pressure, while a pressure transducer specifically converts that pressure into a standardized electrical output signal. In technical applications, pressure transducers are typically used when signal integrity and accuracy are critical.
There are many types of pressure sensors and pressure transducers:
Gauge pressure sensors – measure pressure relative to atmospheric pressure
Absolute pressure sensors – measure pressure relative to a perfect vacuum
Differential pressure sensors – measure pressure difference between two points
Digital pressure transducers – provide digital output for integration with modern systems
High-temperature and high-pressure transducers – built for harsh environments
Each pressure sensor and pressure transducer type is designed for specific use in aerospace, oil and gas, automotive and industrial markets.
Pressure transducers are often used in more simple or less industrial types of environments. A pressure transducer is best suited for applications where signal strength, noise resistance and extra capabilities such as diagnostics are not needed.
