Process control equipment for pure areas

Differential pressure transducers for pure areas of halstrup more walcher "sensitive measuring technique in innovative housing" within almost all ranges the industry take place due to rising quality requirements ever more process under pure space conditions. Around these to ensure supervising of space pressure, temperature and dampness is necessary. The new process control equipment PUC 24 of halstrup more walcher is particularly conceived for this employment. The PUC 24 is essentially a differential pressure transducer with inductive measuring technique, to which a very fine resolution of 0,1 Pa offers with a repetition accuracy of 0,1 %. A cyclic self calibration of the zero point provides for good measured value stability. The measuring range of ±100 Pa is freely scalable. Supplementing entrances stand for temperature and dampness sensors, adjustable from 0... 10 V and/or. 0/4... 20 mA, for the order. All measured values can be read off from an diagram LC announcement well.For separate notifications of emergency there are additional contact contacts. The equipment communicates over professional bus with the superordinate control. The housing for front-concise installation is particularly innovative. The control keys are implemented as high-grade steel transparency keyboards and form at the housing front an even surface. The installation a bay facilitates with establishing the pure area is set. For fixing the PUC 24 four screws are sufficient. This solution developed from the experiences of practice does not only simplify the installation. Above all taking the devices out for calibration purposes or the mutual employment when changes in the process is to be managed by simple disassembly easy and fast.
