Murata has 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 four 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 ±10mg 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 3.3V supply and is suitable for battery-powered operation in remote locations, including IoT-based applications, due to a typical sleep mode current draw of just 3μA.

Housed in a 12-pin pre-moulded plastic housing (8.6x 7.6x3.3mm) that guarantees reliable operation over the product’s life time, the inclinometer is suitable for SMD mounting and is compatible with the RoHS and ELV directives.

Murata will be showing the device in Hall C4 - Stand 141 at electronica in Munich.
