Model D750-100/200 Tiltmeter Series

The D750-100/200 tiltmeter series is the digital version of the Black Diamond Tiltmeter sensor line for geotechnical measurement. It includes a 0.001° and industry standard RS-485 or RS-422 digital output signals.





Black-Diamond-Black-Logo BLACK DIAMOND SERIES

The Jewell Black Diamond Series inclinometer is a low cost, high precision tilt sensor designed with higher accuracy than comparable MEMS devices. It is meant for geotechnical monitoring applications including bridge sag and sway, deflection measurement, platform leveling and structural analysis.
