Choosing the best pressure transducer and data logger are critical in ensuring that the end application runs smoothly.  The data must be accurate for any application or industry, as it is such a key element.  Pressure transducers and data loggers produce information that is critical for efficiency.

Specifics of Data Loggers

Data loggers are used to measure and store the pressure signals that a system puts out.  Data loggers accept one or more sensor inputs, and they sample and save the data at a predetermined frequency.

They accept both analog (temperature, PH, and humidity) and digital inputs (wind speed).

The applications vary from recording wind speed, tracking temperatures of refrigerated storage containers to monitoring flow rates.

Data loggers enable much higher data density than manual recording while also offering higher quality data.  They also save time and expenses by not having a person do the data recordings.

Pressure Transducers

They also refer to pressure transducers, as pressure transmitters and can measure a variety of pressure types.  It converts pressure into an analog electrical signal.

There are many types of transducers depending on the application and need requirements of the lab.

Data Logger with a Pressure Transducer

One type of data logger has a pressure transducer as part of the instrument.  The applications that this is useful for is where pressure needs measuring, but not crucial to the overall well-being of the system.

Data Logger that Stores Process Signals

Another data logger style is the one that receives process signals from the application’s pressure transducer.  The two are completely separate from one another.  A standard data logger can hold from 1,000 to 500,000 signals.

Considerations When Selecting a Pressure Transducer Data Logger

When choosing the best instrument for your needs, there are several considerations that must be made.  The most important criteria are the number of inputs, size, environment, capacity, and digital or analog.  Here is a look at the options and reasons that make these important factors.

• Number of Inputs – The data logger needs to be able to handle the number of input signals from the system’s pressure transducers.
• Size – In many applications, the space for the data logger may be limited, so the size of the actual equipment can be important.
• Environment – The environment that the data logger is working in has a correlation to the material that they make it out of. A common material is a plastic however, it does not work in all situations.  Temperature range is another key factor when looking into the material of construction.
• Storage Capacity – Data loggers only have so much memory capacity. Some applications necessitate measurements every few minutes, while others are every second.  Keep in mind the larger the storage capacity, the more expensive the instrument.
• Digital or Analog – Depending on where the measurements are being taken will depend on if you are using digital or analog. Many data loggers can connect to the cloud so engineers can get instant measurements.
• Pressure Type – There are three pressure type measurements, absolute, gauge pressure, and differential pressure. Based on the type of pressure measurements your application requires, it will determine the specific transducers that are options.
