Delta Ohm BAROsense [BAROsense-M] Barometric Pressure Transmitters, RS485 Modbus-RTU

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 additional analog output, which can be selected in current or voltage via an internal jumper. The current output is user configurable 0/4…20 mA, 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. Versions with optional display are available for immediate and direct reading.

For outdoor installation, a static port with support bracket is available. This is meant to minimize the measurement error caused by the wind flow on the pressure input and to make measurements in open field extremly accurate and reliable.

Barometric transmitter with RS485 Modbus-RTU or ASCII proprietary protocol. Measuring range 300…1100 hPa. Power supply 7…30 Vdc. Operating temperature -40…+60 °C. The CPM12-8D… cable with 8-pole M12 connector has to be ordered separately.
