LVDT sensors are used for applications where a high level of sensitivity and accuracy is required. For applications requiring a more coarse measurement the Basic Displacement sensor offered by SMT is recommended.
Depending on the desired resolution and travel to be monitored, the following sensors are available:
Series 350 LVDT Trans-Tek, Inc. Displacement Sensor
DC Gaging LVDT - Spring loaded spindle with precision linear variable differential transformer. Designed for excellent linearity and high sensitivity. Typically used for stucco or masonry crack monitoring.
Series 353 LVDT Trans-Tek, Inc. Displacement Sensor
This LVDT can be used for example crack monitoring of a building by measuring the relative ovement of two building parts separated by a crack. Uses custom brackets to accomplish this.

Polarity must be observed for proper function. Reversal will not damage the unit.
For best accuracy, recalibrate with designated WiDAQ.
