DMP 333P: new pressure transmitter for high-pressure measurements in viscous media and for technical gases

For all high-pressure applications that require a dead space-free or flush-fronted process connection, BD|SENSORS presents the new DMP 333P pressure transmitter, which is mainly intended for measurements in pasty or viscous media, but is also designed for technical gases such as hydrogen.

Processes with general conditions such as high application pressure or strongly fluctuating temperatures are always a particular challenge in industrial production. 
In order to guarantee precise measurement data acquisition at pressures of 100 bar and above in this environment, BD|SENSORS has developed the DMP333P pressure transmitter. Because of its front-flush process connection, it is primarily intended for applications in which highly viscous media such as oils, adhesives, starch mixtures and so on are processed or treated or in application areas in which only a minimal amount of dead space may be present.

The DMP 333P can also record the pressures of a wide range of technical gases. Particularly with hydrogen measurements, it is advisable to configure the product with a gold-plated process connection in order to avoid brittleness of the material due to hydrogen and achieve high long-term stability. With high process temperatures, the pressure transmitter can be equipped with a cooling section in order to cope with temperatures of up to 200°.

Characteristics of the DMP 333P at a glance

  • The nominal pressure range has been extended from 400 to 600 bar in comparison to the equivalent DMK 331P. The burst pressure and overload of the DMP 333P are significantly higher.
  • The accuracy is 0.35% (standard) or 0.25% FSO (optional). The temperature error within the range of -20 to +80°C is ± 0.75% FSO.
  • The DMP 333P has a standardized G ½” pressure connection, with a stainless steel membrane welded flush to the front.
  • For applications requiring a high degree of technical cleanliness, additional cleaning with regard to hydrocarbons takes place.

The DMP 333P is impressive in the aforementioned applications because of its outstanding media compatibility, performance and mechanical stability as well as its excellent long-term stability.
