1 INTRODUCTION
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 re-
peatability.
The instrument has a digital RS485 output with MODBUS-RTU or proprietary proto-
col. As option, it can be supplied with an additional analog output, which can be
selected by the user in current or voltage via an internal jumper. The current
output is user configurable 0...20 mA or 4...20 mA (default), while the voltage output
must be defined when ordering (0...1 V, 0...5 V or 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.
