ASC MEMS Capacitive Tilt Sensors Uniaxial / Biaxial 4 / 8 Wire System Anodised Aluminium Housing Stainless Steel Housing Protection Class IP67 / IP68 Made in Germany ASC TS-91V1-090 (Uniaxial) Features  Range: ±15°, ±90°  DC Response  High Resolution  Low Temperature Coefficient of Bias  Excellent Long-Term Bias Stability  Wide Temperature Range  High Shock Limit Tilt Sensors MEMS capacitive accelerometers measure both static and dynamic accelerations. Tilt is a static measurement where earth’s gravity is the acceleration being measured. The change in degrees of tilt corresponds to a change in acceleration due to a changing component of gravity that acts on the accelerometer. Low-g accelerometers with high sensitivity result in the highest degree of resolution of a tilt measurement. For a tilt from -90° to +90°, the ASC MEMS capacitive accelerometer experiences acceleration from -1g to +1g. The analog output from the tilt sensor (Vout) can be converted to the degree of tilt (Ø) using the following equation: Ø = arcsin ((Vout - Offset) / Sensitivity) Options  Customised Cable Length  Customised Connector  4-20mA Current Output Applications  Crane Safety Systems  Building Construction Machines  Solar Array Tracking Systems  Ship’s Navigation Posture Measurement  Flap Bridge Monitoring  Track Alignment & Maintenance  Wheel Alignment  Truck Chassis Levelling  Machine Tool Angle Positioning ASC’s tilt sensors yield a nominal full scale output of ±2V for an acceleration of ±1g, which corresponds to a tilt of ±90°. The nominal bias or offset (output at 0g or 0°) is < ±10mV (< ±0.29°) and the output swing is from -2V to +2V with a linear response in the range < ±15°. Description ASC’s tilt sensors TS-9XVY, feature an analog voltage output and are available in two versions, uniaxial and biaxial. Biaxial tilt sensors contain two independent MEMS sensors oriented at 90° to each other to allow perpendicular tilt measurement. ASC’s tilt sensors feature either a light-weight anodized aluminium housing, which provides case isolation against ground loops or a robust stainless steel housing, which has an IP68 rating. The sensor sensitivity and bias is extremely stable over a wide temperature range from -40°C to +120°C. The sensors can be powered using a 6-36 VDC supply, where the output is independent of the supply. ASC’s tilt sensors can withstand shocks as 5000g and feature an aluminium housing (78g) or stainless steel housing (192g) with an integral cable. The sensors can be configured with a 4-20 mA current output as an option, by a temperature range from -20 to +70°C.
