Example of bullet hierarchy:
OARL and inclinometer
• Optical Axis Reference Laser (OARL):
–To be used in AMC. The one checked by AMC
developers are purchased. 2 per telescope.
• Inclinometers:
–One bought / tested confirmed to be broken.
–We bought a ‘better-looking’ sensor
• Tuff Tilt Digital (D801-WL-D) by Jewell
Instruments
• +/- 50 deg range, 7 arcsec precision
• cheaper (~1.5kE)
• -25 - 70dC (operational)
• IP65 (but we put it inside another box)
–We are happy with it. We bought another one
with narrower range (+/- 3 deg, 0.3 arcsec)
• Box w/ adjustments is under design (by
MPI).
• Control under PLC (with profinet gateway)
