0-10V 

ixo65

Which measure range has the pressure sensor?

Which signal has the analog output? 0-10V? 0/4-20mA?

Hello Luna,

Proceed as follows to check for leaks:

You use two min/max blocks (mode 3) for this. The first is triggered at the start of the test and saves the pending value. At the same time, a switch-off delay is started for the duration of the test. When the output of this delay falls, you trig the second min/max block. You then subtract both values from each other with a comparator and thus get the pressure loss.

 You are an angel. Thank you! This helps me a lot!

 mbar is vacuum pressure. 0,001 bar = 1 mbar

Luna.

1200–1 · 10⁻⁴ mbar

???

What is this? 1200 mbar? 

 Max to min of the range the sensor can measure

ixo65

It is clear to me that 0.001 bar = 1 mbar.

But what is:
1200-1 · 10⁻⁴ mbar?

Have you a link to the sensor?
