Dif­fer­en­tial pres­sure trans­mit­ter – HE 5409 from HESCH

Dif­fer­en­tial pres­sure must be recorded and mon­i­tored when small pres­sure dif­fer­ences can have large effects.
Dif­fer­en­tial pres­sure trans­mit­ters thus per­form 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 trans­ducer – HE 5409 reli­ably deliv­ers exact mea­sured val­ues and is also char­ac­ter­ized by fast com­mis­sion­ing thanks 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 under “Tech­ni­cal Data”. Spe­cial mea­sur­ing ranges are avail­able on request.
