Electronic Pressure Switch Precont® PS4

Eggenfelden, 16.06.2016

The devices of the Precont® PS4-series are electronic pressure switches for monitoring, control as well as continuous measurement of pressures in gases, vapors, liquids and dusts.

ACS-CONTROL-SYSTEM GmbH developed a new design for the controls of these pressure sensors (Previous series: Precont® PS). In addition, the devices have been shortened, so that the sensors are now even more versatile.

We have provided more clarity and ease of use the devices present themselves with the easy operation and good readability due to the 3-key operation display with tactile feedback.

Due to the device construction with

  • Pressure ranges depending on the measuring cell up to 1000 bar (e.g. Precont® PS4SM)
  • Process temperatures from –40°C…+135°C (e.g. Precont® PS4SC),  or from –20°C…+150°C (e.g. Precont® PS4LM)
  • Process materials high purity Al2O3-Keramik / CrNi-Stahl

as well as the availability of a variety of hygienic resp. standard process connections like

  • Thread ISO 228-1 with front-flush O-ring gasket, EHEDG-conformal (e.g. Precont® PS4LM)
  • Dairy coupling DIN 11851
  • Varivent®
  • Tri-Clamp® / Clamp
  • DRD
  • Flange DIN EN 1092-1
  • Aseptic tube coupling DIN 11864-1-A, APV-Inline, BioControl®, SMS, flanges acc. to DIN and ISO on request

and the availability of industrial standard process connections like

  • Thread connection ISO 228-1, EN 837 manometer
  • Thread connection ISO 228-1, inner bore 11,4mm
  • Thread connection ISO 228-1
  • Thread connections metric resp. ANSI NPT – on request

the device is especially suitable for the use for hygienic and aseptic applications in

  • Food and beverage industry
  • Pharmaceutical industry
  • Biotechnology
  • Sterile process engineering

as well as general applications in

  • Machinery and plant engineering
  • Air-conditioning and refrigeration plant engineering
  • Hydraulic and pneumatic systems
  • Process industry
  • Environmental technology

The pressure switches are suitable for demanding measuring requirements.

Due to their high accuracy and the high flexibility of configuration, the device can be suited a wide variety of applications.

The pressure switches of the Precont® PS4 – series with front-flush diaphragm have been specifically designed for the measurement of viscous, paste-like, adhesive, crystallizing, particle-laden and contaminated media, which would clog the pressure channel of conventional process connections.

The front-flush diaphragms of the Precont® PS4 are completely welded with the process connection and supplied with positive seals. A reliable, dead-space free sealing between the process connection and the process adapter resp. measuring medium is thus assured (Precont® PS4SC, Precont® PS4LM und Precont® PS4SM).

Through its optimized and EHEDG-conformal design, the front-flush process connection of the Precont® PS4LM enables the cleanability of the wetted diaphragm to be integrated into the process. The device is particularly suitable for the special conditions of CIP/SIP cleaning processes, such as chemical stability towards cleaning liquids and high temperatures. Low-maintenance and trouble-free pressure measurement is thus also guaranteed in critical applications with frequently changing media.

The robust design and the high-quality workmanship turns the device into a very high quality product, which even the most adverse environmental conditions cannot affect, whether the lowest temperatures when used outdoors, extreme shock and vibration or aggressive media.

A captive laser marking of the type label ensures the identifiability throughout the entire lifetime of the device.

Obviously is the optional marking of a measurement point designation resp. TAG, a customer label or of a neutral type label, of course also per laser marking.

A LABS-free resp. silicone-free version, a factory calibration with calibration certificate and a customer specific configuration resp. preset is also optionally available like a material test certificate EN10204 3.1 or factory certifications for drink water resp. food suitability.

Customer specific special versions can be realized on request, e.g.

  • software adaption (menu navigation, special functions, etc.),
  • changed terminal assignment resp. connector orientation,
  • design adaption of the user surface,
  • special designs for the process connection,
  • other fill fluides
