SQ-RI SERIES RUGGED PACKAGED INCLINOMETER, CAN2.0B/J1939 In Dual-Axis Mode the RIW sensor measures inclination between the earth and its X and Y axes with a range of ±70 o. The SQ-RI contains a high accuracy inclinometer, robust power conditioning and a CAN2.0B/J1939 interface controller all potted in an industrial enclosure. A Deutch DTF series connector is standard; M12, flying lead and other connector options are available. In Single-Axis Mode the RIW sensor measures full-scale rotation about the Z axis with a range of 360 o. The sensor must be oriented such that the Z axis is parallel to the ground. FUNCTION LOW RANGE “RIL” MODEL ± 70 º dual axis angle measurement 360 º single axis angle measurement WIDE RANGE “RIW” MODEL The sensor measures between earth and its X and Y axes with a range of 360 o in one axis and 180 o in the other. WIDE RANGE "RIW" MODEL Wide range 360 º x 180 º dual axis angle measurement CAN BUSSING OPTIONS The SQ-RI supports CAN2.0 bus rates up to 1.0 Mbps and can be connected to the bus either in-line or on a tap. The CAN bus is internally terminated in models with a single connector FEATURES ± 0.1 º and ± 0.01 º resolution options IP65, IP67 and IP68 options Low temperature drift Factory calibrated angle output High reliability solid-state MEMS Digital filtering for stable measurement APPLICATIONS Platform and vehicle leveling Satellite dish and antenna alignment Machine control and monitoring Angle measurement and recording Computer input, head tracking, and mouse pointing ALTERNATE HOUSINGS The inclinometer uses two factory calibrated accelerometers to measure and compute angles made between its axes and the gravity vector. The trigonometric conversions between acceleration and angle are made by an onboard processor. Digital filtering reduces the impact of spurious acceleration and vibration on the reported angle. A variety of enclosures are available. Please consult the factory for different enclosures, connectors and cabling options. 10 Water St. Lebanon, NH 03766 USA Page 1 of 14 www.signalquest.com info@signalquest.com

SQ-RI SERIES RUGGED PACKAGED INCLINOMETER, CAN2.0B/J1939 ADDRESSING Device IDs can be factory set or specified using the ADDR_0 and ADDR_1 lines on the primary connector. When addressing is specified by the ADDR_0 and ADDR_1 lines the default (open) state is logic ‘1’. Connect ADDR_0 and ADDR_1 to ground as appropriate to specify the device address. Device functionality is as follows: RIL Model: Device ID Mode Single-Axis Single-Axis Single-Axis Dual-Axis Mode Tilt Tilt Tilt Gimballed CAN PACKET DATA FORMAT: DUAL-AXIS (RIL), TILT/GIMBALLED MODE (RIW) PARAMETER DEFINITIONS P1: Parameter...

SQ-RI SERIES RUGGED PACKAGED INCLINOMETER, CAN2.0B/J1939 ORIENTATION TERMINOLOGY Gravity means a vector pointing from the device toward the center of the earth. X means a vector parallel to the “X” arrow printed on housing label Y means a vector parallel to the “Y” arrow printed on the housing label Z means a vector passing through “Z” arrow printed on the housing label Horizontal means the arrow is pointing at a right angle to gravity. Straight Down means the arrow is parallel to gravity. Straight Up means that the arrow is anti-parallel to gravity (i.e. pointing toward the sky). Plumb...

SQ-RI SERIES RUGGED PACKAGED INCLINOMETER, CAN2.0B/J1939 SQ-RIW MODEL TILT MODE In Tilt Mode the X Tilt and Y Tilt angles are measured between gravity and the white silkscreen arrows printed on the main circuit board. If you passed a Plumb Line through the inclinometer’s X, Y, Z origin, the X and Y Tilt angles could be measured by placing a protractor’s straight edge on the plum line and then reading the angles made with each arrow. Y Tilt = Pitch (first angle) X Tilt = Roll (second angle) Holding Y Horizontal When X is Horizontal and Z is Straight Up, X Tilt = 90 º. When X is Horizontal...
