Description

Bluetooth Low Energy (BLE) strain bridge transmitter module for wireless telemetry of strain-bridge transducers (load cells, torque sensors, strain gauges, pressure modules). Delivers high-resolution, low-power measurements to mobile devices (iOS/Android) via BLE advertising (broadcast) and paired connections, with onboard configuration/calibration via the BTS Toolkit app. Typical use cases: wireless sensor telemetry for test & measurement, OEM integration into weighing systems, portable data collection, and mobile dashboards.

Compatibility & Integration

Integration notes
Integration is via BLE advertising and paired BLE connections. BTS advert format and encoding are available to support custom app integration. The BTS Toolkit mobile app (iOS/Android) supports configuration and calibration. For sensor wiring: keep cable lengths <0.5 m; BTS-OEM-1 supports up to four 350 Ω bridges in parallel (with reduced battery life). Product downloads (datasheet, manuals) require login on vendor site.
