Vacuum Pressure Transmitters

Choose vacuum pressure transmitters for measurements over the low vacuum range of 25 to 760 Torr, using an absolute or negative gauge reference vacuum range.

Use these vacuum pressure transmitters to measure partial vacuums on manufacturing processes, food packagers, autoclave sterilizers, leak testers, suction pumps and atmospheric simulators.

Specifying vacuum pressure transmitter requirements

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

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?

Current output type

What current output scaling is required for the vacuum transmitter signal, e.g. 4-20mA, 0-20mA?

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 current output signal to your vacuum measurement instrumentation?

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

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 transmitter.

Process connection

Do you have a preferred vacuum connection for mounting the transmitter? 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.
