Temperature and Humidity Test Chambers

Weiss Gallenkamp have launched the brand new WT3 Temperature Test Chamber & the WK3 Climatic Test Chamber.

The operating philosophy of the new chamber is to enable users to access operating and control functions as well as to provide manual access to processes quickly and conveniently all over the world. The standard chamber is equipped with the large 12" TFT touch screen monitor for convenient and easy operation. Furthermore, the chambers are equipped with an illuminated CONTROLPAD* that permanently displays the current operating state and the operating parameters. Users thus have a clear view of all important processes and can complete their work just using their fingertips.

  Infotainment ... Virtually without any limits

• 12" TFT-colour touch screen display
• Lighted CONTROLPAD* for displaying the operating state and the actual values
• Industrial PC with Windows XP Embedded
• Integrated recording of measurement data
• Data transfer via Ethernet or USB stick
• Process visualization for circulating air and cooling circuit
• Auto-adaptive control system with continuous self-optimisation
• Networking with other test systems possible
• Remote control and remote monitoring possible via intranet or internet
• Integrated service information system

WT3/WK3: Principle and design The functional principle ...

An air stream that is temperature conditioned and/or air conditioned precisely to the entered set values continuously flows through the test space and ensures an optimum spatial distribution of air and temperature with best constancies in terms of temperature and humidity.

Generously dimensioned axial fans with an external drive motor draw the air out of the test chambers. This circulating air then flows through a fin-type heat exchanger in which it is cooled if required. An electrical heater installed behind the heat exchanger heats the circulating air. The stream of air then passes over a water bath; integrated heating elements ensure quick and precise heating of the water.

The humidity of the test space air is measured psychrometrically. Depending on the climate the humidity sensor thermometer is wetted automatically and cleaned in the process. This considerably increases the service life.
