The PTAM27L series MEMS-based inclinometer from ASM Sensors (Elmhurst, NY) is designed for single- and dual-axis tilt angle measurements. For single-axis versions, measurement ranges span from ±15° to ±180°, in increments of 15°. For dual-axis versions, the measurement ranges span from ±15° to ±60°, in increments of 15°. The inclinometer is an extension of the POSITILT® MEMS-based inclinometers. The wear-free sensing technology provides shock resistance. The housing is rated IP64 and has a height of 10 mm. The device offers 0.1° resolution and ±1° linearity.
