Dif­fe­ren­tial pres­sure trans­mit­ter – HE 5409

Dif­fe­ren­tial pres­sure must be recor­ded and moni­to­red when small pres­sure dif­fe­ren­ces can have large effects.
Dif­fe­ren­tial pres­sure trans­mit­ters thus take on important tasks in plant engi­nee­ring: they not only check the con­di­tion of fil­ter sys­tems, but also moni­tor the volume flows of ven­ti­la­tion and air-con­di­tio­ning sys­tems or mea­sure levels in liquid con­tai­ners.

 

The dif­fe­ren­tial pres­sure trans­mit­ter HE 5409 reli­ably deli­vers exact mea­su­red values and is also cha­rac­te­ri­zed by quick com­mis­sio­ning due to 2-wire tech­no­logy.

 

For inte­gra­tion into your risk assess­ment, the HE 5409 sup­ports you with qua­li­fied values for MTBF and MTTFd.

 

 

Quick assem­bly

The housing is ope­ned and clo­sed without screws thanks to hinge tech­no­logy. This saves time during assem­bly. To open the device, sim­ply place a flat-blade screw­dri­ver at the desi­gna­ted point on the housing cover to pry open the locking mecha­nism. The housing cover remains on the device due to the hinge tech­no­logy and does not have to be com­ple­tely dis­mant­led, as it can be ope­ned up to an angle of 105°.

 

The mea­su­ring ran­ges avail­able as stan­dard can be found in the fol­lowing table. Spe­cial mea­su­ring ran­ges are avail­able on request.
