Precision Glass Scale Linear Encoders
Precision Glass Scale Linear Encoders
Acu-Rite Companies Inc. specializes in precision glass scales used for position feedback in machine tools. These scales consist of an optical-quality glass scale and a photoelectronic reading head that detects a chrome line pattern, generating an electronic signal for precise measurements.
The scales are produced using a photolithographic process in a controlled clean room environment, ensuring high accuracy and repeatability. The facility features vibration-isolated equipment and precision temperature control.
Acu-Rite's glass scales offer superior accuracy with 1,270 chrome lines per inch, providing a measuring interval ten times finer than alternative technologies. This results in exceptional accuracy for travel lengths from 1” to 120” with resolutions from 10µm to 0.5µm.
The scales are designed to withstand harsh conditions, including extreme temperatures and contamination. They are enclosed in aluminum housing with sealed end caps and feature a chemical-resistant lipseal for added protection.
Each scale undergoes rigorous testing for performance and accuracy, with calibration performed in a temperature-controlled environment. A graph of accuracy performance is included with each scale.
Acu-Rite offers various models, including the SENC 50, SENC 150, ENC 250, and ENC 125, each designed for specific applications and available in different travel lengths and resolutions.
Acu-Rite maintains a global distribution network for sales and service support, ensuring prompt delivery and technical assistance.
Acu-Rite's precision glass scales are known for their reliability, accuracy, and durability, making them a preferred choice for machine tool manufacturers worldwide. The company is committed to continuous improvement and offers a 3-year warranty on its products.
