General Purpose

Columbia Research Laboratories
This group of accelerometers is made up of the 3000 and 5000 Series. The 3000 Series are standard size units, including many with all welded construction, that are hermetically sealed for use in dirty and humid environments. The 5000 Series are smaller and lighter in weight than standard units. Characteristics are almost identical except that with miniature units higher natural frequencies and shock levels can be obtained due to their inherently reduced mass. Sensitivities, however are somewhat lower. High Temperature models are available that operate to +500°F. For best performance use with the Columbia Model 4601 Charge Amplifier or Model 5810 Inline Charge Converter.

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.
