Process control equipment in the new Design

The process control equipment PUC 28 of halstrup more walcher supplements the series of the process control devices. With smooth plastic surface it is particularly conceived for the employment in pure areas.� In pure areas the increased air pressure is one of the substantial sizes it to supervise is valid. Beyond that dampness and temperature play a relevant role. In order to be able to indicate all climate conditions in equipment, halstrup more walcher its process control equipment equipped PUC 28 for the pressure measurement with additional entrances for the connection of external temperature and dampness sensors. These are adjustable of 0 � 10V and/or 0/4 � 20 mA. Thus all measured values in a common Grafic LC announcement can be read off clearly. Communication with a superordinate control can take place via professional bus. For the differential pressure measurement the devices are equipped with inductive measuring technique, which offers a very fine resolution of 0,1 Pa with a repetition accuracy of 0,1%. A cyclic self calibration of the zero point provides for good measured value stability. An inserted valve ensures high overload security. The measuring range of � 250 Pa and/or � 100 Pa is freely scalable and additional contact contacts makes possible the binding more externally alarm giver with the PUC28 stands now also an inexpensive variant with smooth surface for the order. The plastic surface insensitive to the usual cleaning agents predestines the PUC 28 for the installation in pure areas. It makes the front-concise installation possible, whereby even the transparency keyboard forms an even surface at the housing front. In an optional execution can be done without taking the devices out for calibration from the pure space wall. For this two pressure connections at the equipment front are available.
