Temperature Chart Recorders
* Temperature and/or humidity recording and controlling at low cost.* Simple installation and maintenance requirement.
* Uses proven bimetallic coil and hygroscopic membrane for reliable results.
* Electrical control/alarm option available.
* Choices of ambient or sampling mode of recorder.
* Temperature and humidity values are recorded in different coloured inks for clarity.
* Suitable for wall or flush pannel mounting for easy installation.
* Short case ideal for shallow compartments.
* Portable stand available.
* All mechanical versions available.
The temperature and humidity circular chart recorders uses the proven design combination of bimetallic coils and hygroscopic membrane for the direct measurement of temperature and humidity.
Changes in atmospheric temperature and humidity are detected by the two elements within the recorder. The bimetallic coil monitoring the temperature and the hygroscopic element the humidity.
air is drawn through the instrument and over the two sensing elements by an electrically driven fan. Expansion, or contraction, of the bimetallic coil, due to temperature change, causes pen movement by direct linkage. Similary a change in humidity causes extention, or contraction, of the hygroscopic membrane and direct linkage again causes movement of the second pen.
Fitted to the pen arms are fibre-tipped pens which are readily replaceable without mess. Each of the two pens traces in a different colour for ease of recognition.
Charts are supplied with the minimum valuse of temperature and humidity at the centre. Standard charts durations are one revolution every 24 hours of 7 days with special durations available on request. Multi-speed chart drive customer selectable is available. mechanical versions single speeds are also available.
