Windows-based software for monitoring bolt loads

The RS-232 and Analog Converter connects a BoltSafe CMS load cell to any data acquisition system (DAQ), computer, or PLC, automatically scaling the output (5Vdc, 10Vdc, or 20mA) based on the maximum bolt load. Users can adjust the load range as needed. It includes free Windows-based software for monitoring bolt loads and setting alarms for deviations (in kN or percentage). The converter can operate independently to trigger alarms or warning lights and supports a complete serial communication protocol for custom integration, offering digital and analog outputs of 0-5Vdc, 0-10Vdc, 0-20mA, and 4-20mA.

How the RS-232 and Analog Converter Works

The RS-232 and Analog Converter connects a BoltSafe CMS load cell to any data acquisition system (DAQ), computer, or PLC. It automatically scales the analog output from the sensor, where the maximum bolt load corresponds to 100% of the output (5Vdc, 10Vdc, or 20mA). Users can request adjustments to the minimum and maximum load range for specific measurement needs. The converter is compatible with free Windows-based software that enables users to monitor bolt loads and set alarms for load deviations (in kN or percentage of full scale). Additionally, it can function independently to trigger alarms or warning lights. The complete serial communication protocol allows for integration with user-specific software, offering both digital readouts in RS-232 and analog outputs of 0-5Vdc, 0-10Vdc, 0-20mA, and 4-20mA.

How to Use the Analog Converter

One RS-232 and Analog Converter can be connected to a single BoltSafe CMS sensor. Once linked to a DAQ, PC, or PLC, the bolt load data can be read and processed. The built-in relay functionality allows the converter to act as an alarm or trigger other warnings. It can also be used to control external equipment, such as pumps or torque tools.

Variations of the Analog Converter

The RS-232 and Analog Converter is available in two configurations: a plastic DIN rail version suitable for use inside a control box and a dustproof, watertight aluminum enclosure with connectors for easy plug-and-play setup. The aluminum version is designed for rugged environments, while the DIN rail version is ideal for projects requiring multiple converters and sensors.
