Tilt Measurement

Fredericks TrueTILT™ tilt sensor line offers both electrolytic tilt sensors and MEMS technology for an innovative and proven method of measuring anywhere from ±90° down to ±0.5° with high accuracy ranging from ±0.1° (±360 arcseconds) to ±0.0003° (or ±1 arcsecond). Generally, as the range of a tilt sensor decreases, the accuracy increases, which can be seen by looking at our tilt measurement options below. Note that our highest accuracy and glass sensor solutions are typically higher cost, and we’re here to help with cost-benefit analysis of specific solutions. Our tilt sensors are used in a wide variety of applications ranging from RV leveling and construction vehicle leveling to extremely high accuracy markets like geotechnical and structural health monitoring.

In addition to the tilt sensor component for board level designs, we also offer complete electrolytic tilt sensor circuits, electrolytic inclinometers, and MEMS inclinometers that are environmentally sealed and designed for industrial and outdoor use. We have an engineering department including electrical, PCB layout, software/firmware, and mechanical design expertise, so we’ll work with you to build a solution specific to your needs. A complete list of all of our tilt measurement solutions is below.

TrueTILT™ Wide Range

Electrolytic Tilt Sensors

These electrolytic tilt sensors are designed to give wide range measurement up to ±60° with high accuracy from ±0.1° to ±0.05° in one or two axes. They're also the lowest cost sensors we offer.

All electrolytic tilt sensors require an electrolytic tilt sensor circuit (also commonly referred to as signal conditioning or a signal conditioner) to provide a tilt angle output. This can be built into your system or you can purchase an electrolytic tilt sensor circuit we’ve designed. Our circuits are optimized for the best performance from our sensors.

Signal Conditioners - Electrolytic Sensor Circuits

Electrolytic Tilt Sensor Circuits

Electrolytic tilt sensors require a basic electrolytic tilt sensor circuit to generate a tilt angle output. These are often called signal conditioners, signal conditioning boards, or electronic tilt sensors. In most cases our sensors can be mounted directly onto the PCB. These electrolytic tilt sensor circuits have many optional outputs including analog 0 to 5 V DC, RS-232/RS-485, and SPI communications.

Our electronic tilt sensors include convenient mounting holes and connectors allowing you to simply integrate our circuits into your designs. If you’d prefer to integrate our electrolytic tilt sensor circuit into your board-level design, we have an engineering department that can help! We have electrical, PCB layout, software/firmware, and mechanical design expertise, so we’ll work with you to build an electronic tilt sensor specific to your needs.

MEMS Sensors - Inclinometers

MEMS Sensors and Inclinometers

Our MEMS tilt sensors and inclinometers are the only products we offer that utilize MEMS core tilt sensing technology. These analog and digital inclinometers are metal housed, environmentally-sealed analog and digital inclinometer sensors with an IP (ingress protection rating) of IP67. Inclinometers are used in many markets and industries including construction and agricultural vehicles where inclinometers provide safety information and other vehicle parameters to the operator.

These analog and digital inclinometer sensors offer a ±90° operating range with accuracy of ±0.1° with optional outputs of analog 0 to 5 V DC and RS-485 digital communications. Analog and digital inclinometers with MEMS tilt sensors are higher cost than our electrolytic inclinometer sensors because of the high accuracy internal MEMS sensor, t. For a lower cost option, view our electrolytic inclinometer sensors.

Tilt Switches

Tilt Switches

Our tilt switches (also referred to as a safety switch or tilt switch sensor module) are very similar to our inclinometers, but instead of a continuous output, tilt switches have a discrete on/off output from either a relay or an open collector. The angle where the tilt switch output changes can be set to specific ranges in one or two axes, up to ±45° tilt. These tilt switches come in plastic or metal housings, environmentally sealed up to IP67, with a cable and flying lads that can be customized with almost any connector you specify. The trip angle can be set by us at the factory or set and reset by you in the field.

The nature of the relay and open collector outputs make these units ideal for various tilt switch applications like construction vehicles and agricultural vehicles. More specific tilt switch applications include boom lifts, scissor lifts, and agricultural sprayers.
