Vacuum Pressure Transducers

These voltage output transducers will provide a linear signal of a few volts that is directly proportional to a specified vacuum range.

Use these vacuum pressure transducers to measure over a portion of the vacuum range such as 0 to 500 mbar absolute or over the whole vacuum range such as 0 to -15 psi gauge.

Depending on your application preference many of these transducers can be specified to measure vacuum either as a positive absolute pressure or a negative gauge pressure. 

Vacuum range pressure transducers with 5 or 10 volt full range output signals for measuring partial vacuums of a few mbar or full vacuums up to minus 1 bar (-15 psi).

Specifying vacuum pressure transducer requirements

Some questions to ask when defining the product requirements for a vacuum pressure transducer.

Vacuum range

What range of vacuum do you need to measure, is it over the whole range from atmospheric pressure to a high vacuum, or a partial vacuum such as reducing the pressure to 90% atmospheric pressure?

Reference type

Are you measuring vacuum relative to full vacuum reading, which would need an absolute reference, or are you measuring vacuum relative to atmospheric pressure, which would require a gauge reference?

Voltage output type

What voltage output scaling is required for the vacuum transducer signal, e.g. 0-5V, 0-10V, 1-5V, or 0.5-4.5V?

Accuracy

How accurate does the vacuum reading need to be in % of full range or vacuum units such as mbar, Torr, inHg, mmHg or psi?

Electrical connection

Do you have a preferred way of connecting the voltage output signal to your vacuum measurement instrumentation?

Do you need a connector or a cable supplied with the transducer?

Media type

What is the vacuum medium being measured? A vacuum measurement application often involves the removal of air, but it can involve any type of gas, and this may affect the suitability of materials used in the construction of the transducer, so it is an important consideration to ensure the long term reliability of the vacuum pressure transducer.

Process connection

Do you have a preferred vacuum connection for mounting the transducer? The level of vacuum being applied can influence the type of connection required, particularly high vacuums where vacuum compatible materials and vacuum seal integrity becomes more restrictive.
