Murata SCL3300 series high accuracy 3-axis inclinometer

Murata announced a new SCL3300 series with 3-axis inclination sensor with a tilt angle output and digital SPI interface

Murata today announced a new 3-axis inclination sensor with a tilt angle output and digital SPI interface. The high performance SCL3300 series of devices will be used in a variety of demanding applications including levelling, tilt sensing, machine control and structural health monitoring.

Based on Murata’s proven 3D-MEMS sensing technology, the SCL3300-D01 is a 3-axis (XYZ) inclinometer with 4 user selectable measurement modes which can be used to optimise the sensor’s performance for different applications and their requirements. The highly integrated device includes a mixed signal ASIC for signal processing along with a flexible digital interface that removes the need for an external ADC, reducing size, power use and design complexity. The SCL3300-D01 features sophisticated tilt angle conversion inside the sensor which enables simple and robust application software and reduces required engineering work. Robust sensor design and advanced self-diagnostics features ensure that the output from the device can be relied on at all times.

The SCL3300-D01 inclinometer provides a ±90° tilt angle output which simplifies measuring software and device usage. The device operates from -40 °C to +125 °C with a typical offset temperature drift less than ±10 mg across the entire operating temperature range. The ultra-low noise density is as low as 0.001°/√Hz for high measurement resolution.

The SCL3300-D01 operates from a single 3.3 V supply and is ideal for battery-powered operation in remote locations, including IoT-based applications, due to a typical sleep mode current draw of just 3 μA. 

Housed in a 12-pin pre-moulded plastic housing (8.6 mm x 7.6 mm x 3.3 mm LxWxH) that guarantees reliable operation over the product’s lifetime, the inclinometer is suitable for SMD mounting and is compatible with the RoHS and ELV directives.
