SEN pressure sensors

The SEN pressure sensors are compact and can be used in a variety of applications. The measuring principle uses a thick film ceramic measuring cell, has very good repeatability and is very reliable. Automatic temperature compensation is provided to give great accuracy. These robust devices are well protected against overload and cope well with pressure peaks and are therefore suitable for use in hydraulic systems. Other typical applications are in compressor and pump engineering and in cooling circuits.

These devices are connected to the process with G ¼, G ½, ¼ NPT or 1/2 NPT threads. Other connections are optionally available. There is a choice of 16 measuring ranges, reaching from -1-0 to 0-600 bar relative pressure.

Analog outputs of 4-20 mA, 0-5 V and 0-10 V are available for signal transmission. Fast on-the-spot information about the current pressure is provided by the practical AUF-type plug-on display. With protection type IP65, the stainless steel and resistant ceramic sensors can cope with jet-water. The protection type IP68 models can handle complete flooding.
