DDM Experts Knowledge “Asked – Known!”
What types of interfaces are there for pressure sensors, what are their advantages and disadvantages and areas of application?
Pressure sensors are critical components in a wide range of applications, from industrial processes to consumer products. A key component of their functionality is the type of interface they use. The following details the most common types of interfaces, how they function, and their advantages and disadvantages.
Types (e.g. 4-20 mA, 0-10 V, 0-5 V, 1-6 V, 0.5-4.5 V)
Application:
In the process industry, 4-20 mA interfaces are often used to monitor pressure in pipelines. The robust and straightforward nature of this interface makes it ideal for long cable runs and harsh industrial environments where precise and reliable pressure measurements are crucial.
Application:
These interfaces are predominantly used in miniature sensors because they require fewer electronic components. This reduces the size and increases the lifespan under high-temperature loads. They are often used in applications with high-temperature stress up to +150°C, such as in vehicle measurement technology, aviation, or the military.
Application:
A typical application for a ratiometric pressure sensor is a battery-powered data logger in field use. The data logger provides a supply voltage of about 5 V for the pressure sensor. Over time, the supply voltage drops. The actual value of the voltage (<5 V) is measured, and the output signal of the pressure sensor is corrected accordingly.
