Coping With Pressure

The SEN pressure sensors from KOBOLD Messring GmbH (Germany), are very compact and can be used in a variety of applications. The approved measuring principle uses a thick film ceramic measuring cell, has very good repeatability and is very reliable. The automatic temperature compensation provides great accuracy. Since the robust devices are so well protected against overloading and also cope very well with pressure peaks, they are highly suitable for use in hydraulic systems. Other typical applications are in compressor and pump engineering, and in cooling circuits.

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

Analogue 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 IP 65, the stainless steel and resistant ceramic sensors can cope with jet-water. The protection type IP 68 models can handle complete flooding.
