The application of the large range of WeKagraph oscillographic recorder is in technical an scientific domain. The thermal recording system is still the most popular method of recording analog signals in a range between 0 and 100 Hz.
Advantages:
- Rugged construction with the assurance of a long life.
- The recording traces are immediately visible, even at slow chart speeds. This is not the case on thermal array recorders.
- Highly accurate recording systems with a large frequency range 0 - 100 Hz.
- Recoding width 80 mm for upt ot 4 channels, 50 mm for up to 6 channels
- Large range of available systems
- Chart speed: 1 mm/min - 100 mm/sec
- Input range: 10 mV/cm - 10 V/cm
Recording method
Rectilinear, thermal with moving iron galvanometer. Stylus heat
control in function of chart speed and signal waveform
Options:
- Additional event marker
- Paper take-up assembly
- Chart speed range 1 : 1000
