High-resolution, digital tiltmeter is sealed to IP65ETLG Inertial Aerosystems is introducing the Applied Geomechanics D711 tiltmeter, a high-resolution, digital, floor-mounted biaxial tiltmeter with NEMA 4X (IP65) protection for continuous exposure to moisture and inclement weather. It is therefore suitable for use in remote monitoring of small movements in dams, structures, large antennas and in earthquake/volcanic zones.

Three models are available with full-scale ranges of +/-0.5deg, +/-5deg and a wide-angle version of +/-80deg. The +/-0.5deg model has a resolution of 1 microradian, and a repeatability of <4 microradian (static).

Operating temperature range is -25 to 70degC (-10 to +100degC storage), with power requirements of 7-28V DC at 27mA; reverse polarity protection is included.

The tilt sensors are fully programmable from a PC using the supplied ZAGI graphical user interface. A powerful firmware command set enables users to control output data rates, data formats, sample averaging and other useful parameters. Customers can specify RS232 or RS485 outputs.

These versatile tilt sensors maintain an absolute reference to gravity and, unlike optical encoders, do not need to be re-initialised on start-up.

D711 tiltmeters bolt or clamp to any surface and are suitable for use in areas of heavy traffic or vibration. The 12.7mm holes in the three corners fit over the provided stainless steel adjustment studs. External measurements are 152 x 152 x 102mm and each tiltmeter weighs 1.4kg.

Each tiltmeter is provided with a 3m hook-up cable and power supply for quick operation with a computer.
