Description

The pressure transmitter DMP 321 is the systematic further development of our in many applications approved DMP 331. It shows an improved signal behaviour and sets new standards in the industrial class. Its metallic diaphragm made of stainless steel (1.4435 / 316L) offers a good corrosion resistance in many industrial processes. The modular device concept allows to combine different pressure ranges with a variety of electrical and mechanical connections. Thus, a diversity of variations is created, meeting almost all requirements in industrial applications. Features accuracy: 0.25 % (opt. 0.1 %) FSO excellent thermal behavior excellent long term stability compact design Optional Features IS-version Ex ia = intrinsically safe for gases and dusts pressure sensor welded customer specific versions
