Columbia Research Labs products

The Columbia Model SA-100MR offers the superior performance of force balance technology with the flexibility of multiple operating ranges for DC and low frequency measurements. The accelerometer is self-contained and provides a high level, low impedance output. No signal conditioning is required in most applications. The full range for Model SA-100MR is specified when the accelerometer is ordered. The range may then be adjusted from 0.05 to 1 times the full range by means of an external resistor. The selected range always corresponds to an output of ±7.5 volts. The noise floor remains constant and does not increase as the scale factor is increased, thereby achieving the optimum signal-to-noise ratio for any range selected.

The Columbia Model 100-P High Intensity Acoustic Sensor (Microphone) is designed for measuring exceptionally wide pressure ranges in applications requiring fast rise times and broad frequency response. This sensor is extremely sensitive allowing very low pressure measurements to 0.005 psi as well as high pressure transient measurements to 5,000 psi at temperatures up to +150 Degrees C. The Model 100-P sensor is small, lightweight and very ruggedly constructed with a stainless steel case, O-ring seal and flush diaphragm. Its small size, broad frequency response and low cost designates this unit an excellent choice for a wide range of applications. Consult the factory for customized versions of this sensor.

Fiber Optic Pressure Seals are designed to provide a safe, convenient, reliable method of exiting fiber optic data lines through a structure while preserving the integrity of either a pressure or vacuum environment.
