About the Ultimate-Precision Digital LBB

The Ultimate-Precision Digital LBB gaging system consists of digital gaging probes daisy chained in a network using T-Connectors (available separately) with DE-9P and -9S connectors. Each Digital LBB gaging probe includes a highly repeatable analog AC LVDT (Linear Variable Differential Transformer) gaging 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 very high accuracy.

The Ultimate-Precision Digital LBB gaging probes are drop-in replacements for Solartron’s devices for the Orbit®2 system and therefore do not require replacement of the Solartron T-Connector in existing applications. They operate in conjunction with the Solartron PCI card or USB module, as well as with our available USB interface (male connector to be connected to one of these interfaces). 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 compatibility with the Orbit® bus measurement system. The Digital LBB gaging 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. Our LBB USB 2.0 full speed compliant interface device (available separately) can be connected to this network (using a T-Connector) to communicate with and allow data transfer to a computer. When our USB interface is plugged into a computer running a Windows® operating system.

The available LBB external power supply is capable of supplying (2 Amps) 31 Digital LBB gaging probes. It features an integral T-Connector which is permanently attached to it. This special T-Connector will interrupt the bus power (power-in pins removed from the male connector) and switch it over to the external power supply, for all Digital LBB gaging probes connected downstream (female connector side). However, if any Digital LBB gaging probes are connected upstream (male connector side) the external power supply, then they will be bus powered.

Other features Digital LBB

• Mounts into existing Orbit®2 applications without the need for T-Connector replacement
• USB device name for easy Windows® recognition
