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 provides exact measured values and is also characterized by fast 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 under TABTechnical Data”. Special measuring ranges are available on request.

Areas of application	– ventilating and air-conditioning systems – heating technology – filter monitor – flow monitoring – building services engineering – firing technology – extraction systems
