BoltSafe Handheld Reader

The BoltSafe handheld reader is a portable device designed to read and store data from both CMS (Continuous Monitoring System) and PMS (Periodic Monitoring System) load cells. For CMS sensors, it connects directly via cable, displaying sensor values on its LCD screen. For PMS sensors, a probe is required; this probe powers the sensor and gathers data through a non-contact interface, connecting to the handheld reader by cable.

Functionality of the BoltSafe Handheld Reader

The BoltSafe handheld reader is a portable device used to read and store data from CMS (Continuous Monitoring System) and PMS (Periodic Monitoring System) load cells. The CMS load sensor connects directly to the reader via a cable, showing real-time load values on its LCD screen. For PMS sensors, a probe is required, which powers the sensor and gathers data through a non-contact interface connected to the reader.

How the Handheld Reader is Used

The handheld reader provides direct readings of residual bolt load both during installation and for later checks on mounted bolts. It displays load values in either kN (Kilonewton) or lbf (Pound-force) and stores up to 256 load cell readings. The device automatically powers down after one minute when no sensor is connected. Data can be transferred to a PC via USB for analysis with “BS Report Generator” software, enabling data storage and reporting for future reference.

Data from a load cell is typically read using a signal conditioner or a digital display unit. The load cell converts the force applied to it into an electrical signal. This signal is processed and amplified by the signal conditioner, and then displayed as a force value (e.g., in kilograms, pounds, or newtons) on the readout device.

To use a load cell sensor- Install the load cell at the point where force measurement is required. Connect the load cell to a signal conditioning system or indicator. Apply the force to the load cell. The load cell will output an electrical signal that is proportional to the applied force. The signal conditioning system will convert and display the force value.

Bolt load is typically calculated by converting the applied torque into load using the relationship between torque and tension.

The bolt load factor is a coefficient used to estimate the tension in a bolt based on the applied torque. It accounts for factors like friction, thread type, and lubrication. The factor is typically provided by manufacturers or determined experimentally. The bolt load factor helps in converting applied torque into bolt load to ensure proper tensioning of fasteners.
