Wyler/Fowler Leveltronic NT and Levelmeter 2000
The new generation Leveltronic NT with remote display Levelmeter 2000 measures small angles with precision and reliability. Especially designed for use in industrial environments with high humidity. Primary applications are flatness measurement of surface plates and measurement of geometrical errors of machine beds and guideways.
Features:
- Rugged precision aluminum housing for protection against external influences
- Connection to Levelmeter 2000 #54-845-000 provides external power
- Bases with magnetic inserts optionally available
- State of the art digital technology combined with the use of modern electronic components allow signal output in digital or analog form
- Fulfills CE requirements (immunity against electromagnetic smog)
- Calibrated in seconds of arc. Models calibrated in mm/m available on request
Levelmeter 2000 allows a number of possible configurations and may be used as a hand-held terminal for digital Wyler levers such as Leveltronic NTs. The large digital display can be adjusted to all commonly used units in inclination measurements.
Levelmeter has two individual measuring channels. Adjust display for following set-up: Single display of channel A or B. Differential mode (A-B). Alternating display of the channels A, B every 5 seconds.
Levelmeter 2000 functions:
- Automatic setting of absolute zero when using reversal measurement.
- Preset function of angles & setting of relative zero. Setting of limits and signalling the respective status, exporting the measured values via RS232 port.
- Power supply: 4 AA 1.5V Alkline batteries (34 hrs). Option: 4 AA 1.2V NiMH rechargeable batteries (20 hrs)
- External power supply: +12...+ 48 V DC/
- Power consumption: Batteries 250 mW, external power supply: 500...3000mW
