The electronic pressure switch EDS 3400 with a flush membrane was designed specifically for applications in which the media could lead to blockage, adhesion or freezing of a standard pressure connection.
Further areas of application include processing with changing media in which residues could cause mixing or contamination of the media.
Like the standard model, EDS 3400 with a flush membrane for relative pressure measurement in a high pressure range via a stainless steel measurement cell with a thin film DMS. The pressure connection is completed at the front with a fully-sealed stainless steel membrane and filled internally with a pressure transfer fluid, which transfers the process pressure to the measurement cell hydrostatically.
The unit can have one or two switching outputs, and there is the option of an additional switchable analogue output signal (4 .. 20 mA or 0 .. 10 V).
Flush front pressure connection
1 or 2 PNP transistor switching output, for loads of up to 1.2 A each
Switching points and switch-back hysteresis can be adjusted independently
Many useful additional functions
Optional Desina®-compliant pin assignment with diagnostic function
