Pressure sensors

Can a 3-wire transmitter also work in a 2-wire configuration?

No.

Can each pressure transmitter measure any medium?

No, the materials stated in the data sheet are to be checked by the customer for resistance.

Can the connector be altered?

The electrical connection cannot be altered.

Can you switch between 4 ... 20 mA and 0 ... 10 V?

No, the output signal is defined in the order and cannot be changed.

What causes zero point drift?

Through the ageing of the electrical components, through temperature and load cycling.

What level of pressure can tear a diaphragm?

The respective burst pressure. This is listed in the data sheet for each product.


What solutions are there against pressure spikes?

For this, we recommend a process connection with a 0.6 mm, or better a 0.3 mm, spark-eroded channel.

Will a pressure transmitter also work without a power supply?

No.

Will the pressure transmitter still work properly when the supply voltage is slightly below the minimum specified level?

Up to a certain pressure, the pressure transmitter will still provide a correct output signal. If the pressure increases beyond this point, however, the output signal will remain at the same value, since the power supply is not sufficient to drive the output fully.
