BaroSCOUT Barometric and Temperature Smart Sensor

Designed to measure and record barometric pressure along with temperature.


The INW BaroSCOUT Smart Sensor is designed to measure barometric pressure, along with temperature. It is an ideal companion to INW’s absolute pressure/level sensors and can be used to adjust their readings for atmospheric pressure.

This industry standard digital RS485 interface device records up to 50,000 records of pressure, temperature, and time data, operates with low power, and features easy-to-use software with powerful features. Constructed with 316 stainless steel, acetal, and Viton®, this sensor provides high accuracy readings in rugged and corrosive field conditions.

The BaroSCOUT utilises an extremely rugged and stable piezo-electric media-isolated pressure element combined with a 16-bit analog-to-digital converter. This provides extremely accurate and stable pressure input into the microprocessor on the circuit board that measures the pressure and stores the data in non-volatile memory.

A 1/2 AA 3.6v lithium battery powers the BaroSCOUT. The unit is programmed using INW’s easy-to-use Aqua4Plus Lite or Aqua4Plus control software. Once programmed the unit will measure and collect data at the time interval programmed. While most will use the BaroSCOUT with INW’s Aqua4Plus Lite or Aqua4Plus software, it is by no means limited to that software. You can use your own Modbus® RTU software or logging equipment to read measurements via RS485, tying into your existing systems and data bases.

Note: The BaroSCOUT is intended for use in atmosphere—not to be submerged.
