Description

BAROsense is a barometric transmitter equipped with a precision piezo-resistive pressure sensor with integrated temperature sensor. The pressure and temperature measurements are digitally processed to obtain a pressure output value compensated over the whole transmitter temperature operating range. The sensor is factory calibrated in multiple points and has excellent time stability and repeatability.
The instrument has a digital RS485 output with MODBUS-RTU or proprietary protocol. As option, it can be supplied with an analog additional output to be chosen from:
• 0/4…20 mA
• 0…5 V
• 0…10 V
The transmitter digital output enables the transmission of the measurements over long distances and connects the transmitter to sensors networks. The pressure can be expressed in different user-selectable units of measurement.
Optional LCD display. Optional input for combined temperature and relative humidity probe. Also available with optional static port and support bracket to minimize the effect of dynamic pressure due to the wind in open field measurements.
