Pressure Sensors with IO-Link

Installation
  DANGER
Risk of death
Risk of death from flying parts, escaping medium and 
electrical shock.
 ► Always install pressure sensors with pressure and 
power turned off!
 ► Operate the device only within specifications (as per 
data sheet)!
NOTICE
Damage to the sensor
High temperatures and rapid pressure spikes beyond the 
specified limits can result in damage to the sensor.
 ► Do not exceed limits (see Technical Data)!
NOTICE
Damage to the membrane
The membrane on the front flush sensor is very sensitive 
to mechanical stresses.
 ► Do not touch the membrane!
 ► Wait until shortly before installation to remove 
the packaging and cover cap, to ensure that the 
membrane is not damaged. Retain the cover cap.
Installation notes
–  If there is a risk of damage from lightning strike or 
overvoltage, insert an overvoltage protection between 
the feed device resp. control cabinet and the device.
–  For hydraulic systems position the device so that the 
pressure connection faces up (venting).
–  When using in steam lines provide a cooling line.
–  Installation must not cause any mechanical stress at 
the pressure connection.
–  Front flush sensors: Attach clamp fittings using a 
suitable connecting element (e.g. half-ring or snap ring 
connection) per manufacturer specifications.
When installing outdoors or in damp surroundings observe 
the following:
–  Make the electrical connection as soon as the device is 
installed. Otherwise prevent moisture entry using an 
appropriate cover cap or similar.
–  Install the device so that it is protected from direct 
sunlight.
–  Devices with gauge reference in the housing must be 
installed so that the gauge reference required for the 
measurement is protected against dirt and moisture.
–  In damp surroundings and when the device is wet, do 
not turn the display to the desired position or operate 
the buttons.
Installation
Check before installation:
–  Is an appropriate seal available?
–  Does the sealing surface have a flawless surface?
For pressure sensors with external threads do not use any 
additional sealing material such as tow, hemp or Teflon 
tape!
 ► Tighten the device by hand in the holding threads. Use 
an appropriate open-end wrench to tighten and 
observe the following tightening torques:
