Function and application

The SDE3 has been designed for monitoring changes in pressure in the
compressed air system or terminals. Variants for relative pressure measurement
and differential pressure measurement are available:
Type Description
SDE3-...Z 1x differential pressure
p1 – p2
6
SDE3-...S 1x relative pressure
SDE3-...D 1x relative pressure pA
1x relative pressure pB
SDE3-...M 1x relative pressure pA
1x relative pressure pB
1x differential pressure
analysis pB
SDE3-...V1M 1x differential pressure
analysis pA – pB
1) In A/B: input value for sensor element A/B. In C: calculated
2) Measuring pressure p1 – reference pressure p2

Requirements for product use

Warning
Depending on the functions of the machine/system, the manipulation of signal
statuses can cause serious injury to people or material damage.
• Note that if the switching characteristics of the switching outputs is modified
in EDIT mode, the new status becomes effective immediately.
Enable the password protection option (security code) to prevent accidental
alteration by an unauthorised third party (è Chapter 5.3 section Set security
code).
Warning
The usage of the SDE3 in combination with impermissible media can lead to
personal injury or material damage.
• Use the SDE3 only with compressed air
• Observe the specified air quality class (è Chapter 11 Technical data).
