LILY Self-Leveling Borehole Tiltmeter

LILY Self-Leveling Borehole Tiltmeter

Highlights:

Using a high-precision electrolytic tilt sensor, units deliver resolutions to 5 nano radians; the dynamic range is ±330 µradians. Units also feature a ±10 deg. leveling range for easy installation downhole. Output is RS-232 or RS-422 (RS-485 full-duplex) and includes timestamp and compass bearing. Data can be saved to file externally or to LILY’s on-board flash memory (75,000 sample max) using fill/stop or cyclic memory modes.

Units are fully submersible to 3000 psi. Titanium is also available for +5000 psi applications. The culmination of over 30 years of tilt sensor experience and expertise, the LILY represents the pinnacle in precision sensor engineering.

Model MD900-T Digital Clinometer

Model MD900-T Digital Clinometer

Highlights:

The biaxial model MD900-T is an economical digital clinometer with powerful firmware features. User programmable settings include AUTO-zero (tare), baud and output rate, sample averaging, and more. Output is RS-232 or RS-422 (RS-485 full-duplex). The MD900-T easily integrates with a variety of GPS receivers and supports Trimble TCM, NMEA XDR, BAE, and Ashtech output protocols. Units ship standard with 6-ft. hook-up cable and a 100-240VAC power transformer. Use the MD900T for industrial pitch and roll measurement, marine piling, dredging and construction systems, platform leveling, geotechnical monitoring, and more.

Model MD908 ‘IRIS’ Tilt Switch

Model MD908 ‘IRIS’ Tilt Switch

Highlights:

The IRIS Tilt Switch and Controller is a powerful tilt controller device that combines a digital, dual-axis clinometer and advanced firmware features in one compact unit. This remarkable instrument enables you to measure and respond to rotational movements in any direction concerning the unchanging gravity vector. Units ship standard with a 24-inch hook-up cable. IRIS is an ideal choice for OEM applications, where it can be used to maintain platform levelness, avoid tip-over conditions, prevent out-of-range movement, and perform other control functions.
