Columbia Research Labs products

The Columbia S Series LVDTs are designed to sense linear displacement over the ranges of +/-0.04” to +/-0.30” and translate this motion into a precisely proportional voltage for measurement and control. These transducers consist of a coil assembly potted and mechanically swaged into a 7/8” diameter housing with a separate moveable core. The ¼” diameter core allows a radial clearance of 1/32” between the moveable core and bore of the coil assembly. The corrosion-resistant stainless steel housing provides effective shielding to contain the magnetic flux within the transformer, as well protection against external magnetic fields.

The Columbia Model SI-705B is an electric tilt sensor based upon force balance accelerometer technology. The Model S1-705B will produce a high level low impedance output proportional to the sine of the tilt angle. Unique electronic damping and desensitization circuitry allows tilt measurements in strong vibration and shock environments. The Model SI-705B is self-contained requiring no additional signal conditioning in most applications. The Model S1-705B is well suited for many OEM and industrial applications and are intended for applications such as platform stabilization, surface mapping and measuring tilt angles in remote locations. Consult the factory for customized versions of these sensors.
