A-501A Turbine Bore Sweep Unit

DESCRIPTION
The A-501A Turbine Large Bore Sweep Unit, and the A-501A Turbine Small Bore Sweep Unit are fixtures with digital indicator sweep arms that measure bore diameters, and position the A-502A Turbine Target Bracket to user-specified setpoints in reference bores. These rugged, portable, and lightweight units are easy to set up and are accurate to .001". They have the same diameter as the T-218T Turbine Bore Target.

APPLICATIONS

FEATURES

• Fast, easy setup.
• Accurate to .001".
• Digital indicator sweep arm quickly measures bore diameters and positions A-502A Turbine Target Bracket to user-specified set points in reference bores.

DESCRIPTION

The A-502A Turbine Target Bracket is used to hold and position the T-218T Bore Target in the center of a reference bore. It uses standard angle iron and magnetic bases (2) for easy mounting to a split joint and is designed to work with the A-501A to quickly and easily position T-218T Turbine Bore Target in the center of the bore.

APPLICATIONS

• Turbine bore alignment

FEATURES

• Rugged, compact, lightweight.
  
• Uses standard angle iron and 2 magnetic bases for easy mounting to split joint.
• Designed to work with A-501A to quickly and easily position T-218T Turbine Bore Target in the center of the bore.
• Once A-502A Bracket is centered in the bore with the A-501A Turbine Sweep Unit, the T-218T Turbine Bore Target is easily inserted and the bore center reading is quickly determined.

EL-905 ELECTRONIC BUBBLE LEVEL

DESCRIPTION

EL-905 Electronic Digital Bubble Levels are the only electronic levels of their kind that use a standard bubble level and sophisticated electronics to create a very accurate, durable and stable level. It is accurate to 0.5 arc seconds with a range of +/- 1000 arc seconds (0.06”/ft or 5 mm/M). The best news of all is that the new digital bubble level technology has enabled us to price the units at about half the price of a standard electronic level!

The EL-905 has a fixed display and the EL-905 has a rotating display that swivels nearly 360 degrees for easy viewing on any side of the level. Each level also features a resolution switch, a unit switch that allows the reading to be displayed in inches/10", mm/M or arc seconds and a Calibrate Mode that allows field calibration.

The EL-905 use a CCD array to read the edge of a standard, very durable bubble level. This means they can be knocked over and dropped from small heights, and it will not hurt the accuracy of the level, nor will it require factory recalibration. Compared to other electronic levels that require an expensive recalibration (up to $600) every time they are knocked over, the EL-905 is the ideal level to handle any harsh industrial environment. In fact, with the field calibration capability, the EL-905 should only need 1 annual calibration for ISO9000 purposes.

The EL-905 features several mounting bases that can be easily switched in the field. There is the standard 10" (250.4 mm) measuring base and a v-block base is available for measuring level of rolls or spindles on HBMs or HMCs. The v-block base also features a strapping system to keep the level from falling off a roll or spindle. Customized bases are also available.

APPLICATIONS

• Measuring level of any horizontal surface
• Leveling machine beds
• Surface plate calibration
• Measuring level of rolls and spindles in HBMs and HMCs
• Measuring the level of paper mill, printing press and other process mill rolls.

FEATURES

• Level is accurate to 0.5 arc seconds (0.00003"/ft or .0025 mm/M)
  [Also available with 0.1 arc second accuracy]
• Large measuring range of +/-1000 arc seconds (0.06”/ft or 5 mm/M)
• Easy-to-see display that rotates 350 degrees (EL-905 only)
• Operational modes:
  ACTUAL - displays the actual level reading
  CALIBRATE - allows the user to calibrate the level using a simple reversal procedure
  In./10”, mm/M or Arcsec resolution modes
• Very stable with little drift
• Standard base: 6"
• Optional bases:
  - 10" and 12" flat base
  - 6” and 10” V-block base for roll level checks (comes with strap to keep it from falling off rolls)
• Durable, compact design
• Comes with durable foam lined case

L-102 BEAM TRANSLATOR

DESCRIPTION

The L-102 is a beam-steering device used to translate the vertical and horizontal position of Hamar's straight-line lasers without affecting the angle of the laser beam. It mounts on a magnetic base and features coarse and fine adjustments for translations as small as .001" and +/- .100" maximum beam displacement.

APPLICATIONS

For use in machine tool and bore alignment with the following lasers: L-723, L-722, L-720, L-720M, L-705/706.

FEATURES

• Translates the vertical and horizontal position of the laser beam without change the beam's angle.
• Coarse and fine adjustment for translations as small as .001".

Also provides multiple-height flexibility to position laser systems at optimal point for taking measurements. It is lightweight, the feet fit inside the stand and it fits into a carrying case that is about the size of standard luggage.

APPLICATIONS

Used with all Hamar Laser continuously rotating laser systems: L-719, L-720, L-720M, L-722, L-723.

SPECIFICATIONS

P-405 REMOTE SCAN OPTICAL SQUARE

DESCRIPTION

The P-405 Remote Scan Optical Square accepts a straight-line laser beam, bends it at a precise 90º angle and produces a continuously rotating laser plane. It uses the T-212 4-Axis Target to qualify or align the optical square to the laser beam. The laser plane created by the P-405 is square to its input beam to 1 arc second. The plane is flat to 1/2 arc second. It can be moved down the input laser beam to create parallel reference planes.

APPLICATIONS

• Machine tool measurement/alignment
• Spindle Z-X travel
• Lathe cross-rail squareness/straightness/flatness
• Column squareness
• Roll alignment

FEATURES

• The plane is generated by a rotating pentaprism that bends the beam at an exact 90º angle, accurate to better than .0002" within a ten-foot diameter circle and .001" within a 50-foot diameter circle.
• Establishes parallel planes by moving the P-405 to different locations along a straight laser beam.
• Uses multiple targets, eliminating the need to relocate the target for each measurement.
• Reduced operating time. The P-405 does not need adjusting for every reading (the "point-and-shoot" method required by manual systems).
