BTS Bluetooth® Telemetry System

Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module

  • High Measurement Resolution: BTS-AM-1 can produce a noise free resolution of 1 in 92000 counts (16.5 bit) when used with a 3mV/V sensor and 1 in 184,000 counts (17.5 bit) when used with a 6mV/V sensor.
  • Simple Integration into iOS and Android Apps: Advert format and encoding as well as details on connected services are available to facilitate integration of the device within custom apps for OEM applications.
  • Range: Ranges achievable between 30 to 90 m line of sight depending on age and quality of viewing device.
  • Advanced Protection: Configuration PIN, View PIN and Calibration PIN allow you to take control of your end users experience and prevent any unwanted changes in configuration that can compromise measurement quality.

A Bluetooth Low Energy (BLE) strain bridge transmitter module that provides access to high quality measurements on a mobile platform such as a phone or tablet in IP67 enclosure for two AA batteries

Bare board format, which allows the module to be built into OEM applications.

The WTS/BTS-BC1 is a battery charger and power supply suitable for the 3V transmitter modules. The WTS/BTSBattery Charger is designed to supply a constant 3.3 V from a Li-ion Battery while also charging the battery from an input voltage. The unit comes pre-configured to provide a charging current of 466 mA suitable for VARTA LIP653450. This module also supports additional batteries providing a charge current of 133 mA via the removal of the leaded resistor (non surface mount).

The BTS-AM-1 is a Bluetooth Low Energy (BLE) strain bridge transmitter module that provides access to high quality measurements on a mobile platform such as a phone or tablet.
The delivery mechanism is BLE which utilizes the flexibility and availability of Bluetooth receivers while maintaining the low power requirements of embedded systems. BTS is built upon two complimentary principles of BLE: 1) broadcast advertising data which enables users to deliver the same data to multiple receivers simultaneously and 2) low power paired connections which can be used in a point to point system.

A free iOS and Android app is available for download, which enables users to create dashboards with varying degrees of detail based on application requirements. It enables BTS systems to be visualized on phones and tablets by using digital displays, gages, tanks and charts. Displayed data can be defined as mathematical expressions consisting of readings from multiple transmitters, functions and constants. The app also facilitates BTS module configuration and calibration.
