The DLBB includes a highly repeatable analog AC LVDT (Linear Variable Differential Transformer) probe guided with a precision linear ball bearing, mated to an in-line digital I/O signal conditioning module.  The circuitry and firmware feature digital calibration and linearity correction of the digital output position signal with extremely high accuracy. The DLBB probes operate in conjunction with our available USB interface module. Our robust dimensional gaging probes are engineered to provide highly precise and repeatable measurements in various industrial, quality assurance and metrology applications. The system is based on an RS-485 half duplex, multi-drop network providing plug-and-play functionality. The DLBB probes convert their position signal into digital data which is then transmitted by the RS-485 network using asynchronous transmission (poll/response). The devices support both standard and buffered modes.
