Pressure measurement is common in a wider variety of labs as it can determine properties like flow, level, airflow, weather systems movement, and height and magnitude of water.  For engineers and scientists, monitoring pressure allows them the knowledge to improve or troubleshoot.  This is why pressure measurement is so vital and accuracy is necessary.

Pressure Transducers

A pressure transducer is a transducer that converts pressure into an analog electrical signal. They then transmit the electrical signals to the controller where they are processed and recorded. We also know it as a pressure transmitter.  Pressure transducers can read and send pressure data quickly.

They use pressure transducers in many control and monitoring applications such as flow, airspeed, level, pump systems, or altitude.  There are various types of pressure transducers depending on the specific use.  There are three pressure references for measuring absolute, gauge, and differential pressure.

Types of Pressure Transducers

There are three main types of pressure transducers.  Each reference a specific pressure measurement.

Absolute pressure transducers measure the pressure comparative to a perfect vacuum, using absolute zero as a reference point.

Gauge pressure transducers measure the pressure relative to atmospheric pressure, an example is a tire pressure sensor.

Differential pressure transducers measure the difference between two pressures on either side of the sensor.

Data Loggers

Data loggers are devices that automatically monitor and record environmental parameters over time.  A data logger has a sensor to receive the information and a computer chip to store it.  Once the data is stored, you can transfer it to a computer for analysis.

There are two main types of data loggers.  The first is the data logger with a pressure transducer built-in.  This data logger is best for applications where pressure should be measured but is not critical to the overall well-being of the system.

The other type is a data logger that stores process signals from pressure transducers.  This data logger is entirely separate from the pressure transducer.  These data loggers can store 1,000 to 500,000 signals.

Advantages of a Data Logger

A data logger provides the ability to take measurements in any location, even during transit, without human intervention.  The logger can space the measurements to obtain transient events or far apart to maximize recording duration.  These advantages are important when measuring pressure specifically weather systems like tsunamis and storms.

A data logger is a more effective, reliable, and accurate piece of equipment than other options and also saves labs time and expenses of having a person doing the recording manually.  The data logger also reduces the time needed for analyzing measurements.
