The PTAM27L series inclinometers from ASM Sensors, based on microelectromechanical systems technology, provide linear output for single- and dual-axis tilt angle measurement. The measurement range is ±15° to ±180°, in increments of 15°. For dual-axis versions, the measurement range spans ±15° to ±60°, in increments of 15°. The series is an extension of the POSITILT family of MEMS-based inclinometers. Wear-free sensing technology offers high resolution and is shock-resistant. The housing is rated IP64 and is 10 mm high, providing ease of installation in tight locations.
