Y level or Wye-level consists y-shaped frames which supports the telescope. Telescope cane be removed from the y-shaped supports by releasing clamp screws provided. These y-shaped frames are arranged to vertical spindle which helps to cause the rotation of telescope. Compared to dumpy level, adjustments can be rapidly tested in y- level.

The Y level or wye level is the oldest and bulkiest of the older style optical instruments. A low-powered telescope is placed in a pair of clamp mounts, and the instrument then leveled using a spirit level, which is mounted parallel to the main telescope.

The Y level, also known as the wye level, is the oldest and most bulky of the earlier optical instruments. A low-powered telescope is installed in a pair of clamp mounts, then levelled using a spirit level set parallel to the main telescope.

Wye level: The essential difference between the dumpy level and the Wye level is that in the former case the telescope is fixed to the spindle while in the Wye level, the telescope is carried in two vertical Wye supports.

Jul 29, 2024 · Levelling is a fundamental aspect of surveying, critical for ensuring that construction projects adhere to design specifications and are built on a stable, accurate foundation. The objective of any levelling instrument is to direct the line of sight in a horizontal direction.

Jun 29, 2021 · Also called wye-level, it has a Y-shape frame that supports the telescope and a vertical spindle that helps to rotate the telescope, unlike the dumpy level. This telescope can quickly test rapid adjustments.

M/S York combined good features of both dumpy and wye levels in one by providing a stop flange screw for reversibility of the telescope and named the level as Cooke’s reversible level.

Oct 7, 2018 · The Wye Level (Y-Level): The telescope is held in two ‘Y’ supports. It can be remove from supports and reversed from one end of the telescope to the other end.

Nov 26, 2024 · Y Level (Wye-Level) The Y level features y-shaped frames that support a removable telescope. The instrument’s structure allows quick adjustments and testing. Advantages: Faster adjustment checks compared to the dumpy level. Disadvantages: Open parts are prone to wear due to friction, requiring regular maintenance.

Apr 15, 2024 · Levelling head consists of two parallel plates with three foot screws. The upper plate is known as tribratch plate and the lower one as the trivet. The lower plate can be screwed on to the tripod stand. By adjusting the screws the instrument can be levelled to get perfect horizontal line of sight.
