An Inclinometer Measures Changes in Angle

An inclinometer, or tilt sensor, is an instrument used for measuring slope, tilt, or inclination by using gravity. An inclinometer creates an artificial plane defined at zero degrees, and measures the change in angle with respect to this plane. These devices go by many names, including: tilt sensor, level sensor, bubble level, angle indicator, clinometer, protractor, slope meter, tilt meter, tilt/slope alarm, pitch/roll indicator, or level gauge. All refer to the same device!

2GIG Engineering manufactures inclinometers using MEMS technology. This technology can replace any existing mechanical inclinometer technology, including electrolytic or silicon liquid, bubbles, hall effect sensors, mercury, and pendulums. Not only does MEMS technology eliminate moving parts or potentially hazardous liquids, it also grants the end-user nearly infinite operation. The advanced technology of the 2GIG MEMS Inclinometer takes all of the difficulty out of automated leveling solutions.

Exterior Features

Bright Red Trip LED – This option is standard for units with trip angles. The highly visible illumination around the perimeter of the cover provides the best possible visibility.

Illuminated Zero Button – A stainless button with illuminated power-on blue LED comes on all models. To set relative zero, hold the button for 3 seconds. To revert to factory zero, hold the button for 6 seconds.

Sealed Enclosure – Captive stainless bolts hold outside of the gasket area to protect against any penetration to the interior, back this up with an epoxy covered circuit to protect against vibration and the harshest environments. Our natural polyol epoxy is derived directly from a plant source using no chemical modifications.

Optional Accessories

Wires and Connectors – 2GIG provides custom terminations for new products or direct replacements. We have a large inventory to provide what you need.

HMI Panel Display – Our sensors can be paired with a customized HMI (human machine interface) LCD screen which can display all readings that the 2GIG MEMs inclinometer can provide. This panel display can communicate with the tilt sensor through hard-wired or wireless communication. The display has the ability to output PWM, digital, and analog signals; as well as reading input analog, 4-20mA, and digital signals for added communication and integration into a user’s design.

What Sets Us Apart

The three biggest difficulties for tilt sensors to overcome are vibration, extreme temperatures, and limited user preferences. 2GIG Engineering has solved these problems and customers will be relieved to know that there is a tilt sensor out there that will do everything they need without restriction.

This Is How We Pitch and Roll

Using an internal accelerometer and gyroscope for each axis, the 2GIG sensor combines the readings by using a complex Kalman-based sensor fusion algorithm. This sophisticated algorithm provides highly accurate tilt degree readings for both pitch and roll.

When Things Get A Little Heated

Our MEMS sensors have built-in temperature compensation, keeping your operation as precise as possible in the harshest environments. Work with a device that can maintain accuracy over the widest temperature range in the industry.

For Every Action There is a Reaction

The 2GIG Tilt Sensor detects and analyzes vibration to provide accurate readings all the time. When conditions change, work with a sensor that can change too.

User Preferences

We have created a MEMS tilt sensor to give the customer maximized flexibility and ease of integration within their design. No longer will your system be restricted by a particular specification.

0-5V Analog Inclinometer

  • High Resolution: 0.01 Degrees
  • -40 to 85°C Operating Temperature
  • Innovative built-in boost regulator provides 0-5V throughout the full input supply of 4-40V

The analog tilt sensor will output a linear voltage within 0-5V corresponding to the specified trip angle. The default range is 0.5-4.5V, with 2.5V as neutral (level) position.

Example: Trip Angle = ±4°, Output = 0.5-4.5V

The graph displays the output behavior for an analog level sensor with a trip angle of 4° in either the X or Y axis. The analog output is symmetric, therefore it will range from -4° to +4° for the voltage range from 0.5V to 4.5V

4-20mA Inclinometer

  • Precision 4-20mA Output with 16-bit Resolution
  • High Resolution: 0.01 Degrees

  • Internal Processing Uses a Complex, Kalman-based Sensor Fusion Algorithm
  • Intuitive smart system for vibration and temperature
  • CE and ROHs compliance
  • Impact-resistant, UV-stabilized, and NEMA 4/4X rated housing

The 4-20mA tilt sensor will output a linear current from 4-20mA corresponding to the specified trip angle. The default range is 4-20mA, with 12mA as neutral (level) position.

Example: Trip Angle = ±4°, Output = 4-20mA

The graph displays the output behavior for a 4-20mA level sensor with a trip angle of 4° in either the X or Y axis. The 4-20mA output is symmetric, therefore it will range from -4° to +4° for the current range from 4mA to 20mA

Switching Relay Inclinometer

The switching relay tilt sensors contain active-high, sourcing DC outputs which are capable of driving currents up to 4 amps per output (2 outputs max). There are two types of output behaviors: normally open and normally closed. A normally open output will turn on once the tilt sensor reaches the specified trip angle, default state is off. A normally closed output will turn off once the tilt sensor reaches the specified trip angle, default state is on.

  • -40 to 85°C Operating Temperature

  • Intuitive smart system for vibration and temperature
  • CE and ROHs compliance
  • Impact-resistant, UV-stabilized, and NEMA 4/4X rated housing

Normally Open Output

The normally open output will output 0 volts or act as an open connection while it is below the chosen trip angle. Once the sensor is tilted to the trip angle or greater, the output will turn on after the specified trip delay.

Example: Trip Angle = 3°, Voltage Supply: 12V

The graph displays the relay behavior with a trip angle of 3° in either the X or Y axis. The output is normally open until the sensor is tilted to ±3° or beyond.

Normally Closed Output

The normally closed output will output volt supply when it is below the chosen trip angle. Once the sensor is tilted to the trip angle or greater, the output will shut off after the specified trip delay and resemble an open connection.

Example: Trip Angle = 3°, Voltage Supply: 12V

The graph displays the relay behavior with a trip angle of 3° in either the X or Y axis. The output is normally closed until the sensor is tilted to ±3° or beyond.

Output Behavior

The block diagram shows a visual representation of the wires on the tilt sensor, including the outputs for one isolated relay (each sensor supports up to a max of 2 relays).

The V+ and GND inputs are to be connected to a DC voltage source, which can be any voltage source within the range of 6-40VDC. When the tilt sensor is tilted past a specified angle limit, it will activate the relay’s coil and cause the relay to switch. While the sensor is in a level position (< trip angle), COM and NC are internally connected. When the sensor is tilted past the specified trip angle (and also after an optional trip delay), the coil will activate and switch the relay. While the relay is in the switched position, COM is connected to NO.
