Linear Motion Tandem Transducer
Columbia Research Laboratories
The Columbia Model LMT-50 is a unitized rugged package consisting of tandem linear variable differential transformers (LVDT's) with probe assembly. The LMT-50 is designed so that the likelihood of a single failure affecting both output signals is extremely improbable. The model LMT-50 offers flight proven performance, even in the most severe environments.

General Inclinometers
Columbia Research Laboratories
Columbia's SI-701 Series of Inclinometers are electronic tilt sensors based on Force Balance Accelerometer technology. They produce high level low impedance output proportional to the sine of the tilt angle. Model SI-701B is a low cost general purpose sensor that can be up-graded with the addition of the Columbia "HP" torquer system (SI-701BI) for greater accuracy and ruggedness. A bi-axial version of both units (SI-702B) is also available. The Model SI-701BI is designed with an output circuit made for 4-20mA data transmission systems for industrial applications. The model SI-701FND is a fluid dampened premium performance inclinometer designed to produce accurate tilt data in extreme shock and vibration environments. The latest addition in the line is Model SI-701WPBI, a waterproof (to 150 feet) inclinometer which operates from a +15 volt supply with 4-20mA output. A single power supply powers both the sensor and the 4-20mA line driver.
