Sensors, transmitters, separators SCK-11 inclinometer with two orthogonal axes high accuracy, temperature compensated high resistance to vibrations precision internal accelerometer The dual axis inclinometer module SCK-11 was designed to stationary measurements of inclinations of two orthogonal axes in relation to earth. Recommended range of measured angles maintains from -70 to +70 deg. While measuring in range -20 to +20 deg. range, the precision is better than 0.1 deg. in both axes. If measured angles exceeds range ±75 deg. (in relation to earth) the measurement error can be higher 3 deg. (at both ends of range). Due storing of new scaling values to internal registers it is possible to change measurement unit and resolution to any other linear. Build in offset registers allows user to measure relative angles and self zeroing after mounting. In addition to two registers containing information about SCK-11 installation plane angle relative to the earth (two angles with the offset function), threre are available additional two records containing information on the accelerations in the same axes, what makes measurement of transducer movement more precision. Indications of these records are expressed in 1/1000 of earth gravity, which corresponds to the reading equal to 1000 when inclination of sensor equals 90 deg. in relation to earth. Additional temperature measurement circuit allows to check temperature of internal accelerometer and compensate the measurements. Internal temperature can be read by user as third measurement channel. Substantial aluminium case with high IP rating, wide operation temp. range and temperature compensation circuit allows to use SCK-11 outside of buildings, with hard environment conditions (containers, platforms, outriggers, jibs etc.). The device should not be used while strong vibrations occurs and must not be used for security systems. SCK-11 is equipped with RS-485 communication interface with Modbus RTU protocol, allowing direct readings of measurements and full configuration of the device. - two measurement channels, - build-in temperature sensor, - resistance for mechanical damages, - aluminium housing.
