Profile Projector Series Provides Stable Dimension, Angle Measurements in Harsh Environments

The Mitutoyo America Corp. has added the PJ-Plus Series Profile Projector to its lineup of metrology products. The Mitutoyo PJ-Plus is a new series of profile projectors that uses LED lighting and provides reliable measurements in manufacturing site environments, according to the company. Mitutoyo states that the PJ-Plus provides stable dimension and angle measurements in harsher environments than many conventional models can handle, such as manufacturing and processing lines.

Key features include:

• LED illumination: According to Mitutoyo, using LED instead of halogen lighting eliminates the need for a main-unit cooling fan, limiting entry of oil, mist, dust and so on into the measuring instrument. LEDs are also intended to reduce lamp burnout and power consumption.
• Stepless illumination adjustment: Stepless illumination control is designed to be more efficient and allow light levels to be set precisely to suit surface textures and color or a workpiece.
• Built-in digital XY counter: The PJ-Plus Series displays XY axes and angle readings in large characters on its front for easy readability meant to eliminate the need for an auxiliary DRO.

The absence of a cooling fan (due to LED illumination) reduces adhesion of oil and dust to the internal mirror and light source to maintain a higher optical performance, according to the company. The LED bulb lasts longer than halogens, meaning less maintenance and reduced down time, Mitutoyo says.
