BAROsense-Pressure Transmitter

Make: Delta Ohm                                      Model: BAROsense
✅ 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.
✅ Measurand : Barometric Pressure and Housing Temperature .
✅ Sensor Type : Piezoelectric  pressure sensor.
✅ Signal Output : RS485 with Modbus-RTU or ASCII proprietary protocol , optional analog output and digital output.
✅ Supplied With : Internal screw terminal header / PG7 cable gland for power supply and output. Optional M12 connector for the T/RH external probe.

BAROsense-Pressure Transmitter:

BAROsense is a full line of barometric pressure transmitters that measure from 300 to 1100 hPa. It has a precise piezoelectric pressure sensor and an integrated temperature sensor. This ensures the accuracy and precision of your measurements in outside conditions such as meteorological or altitude applications, as well as inside environments such as cleanrooms, automotive emissions testing, or pressure compensation measurement in internal combustion engines.

Barosense has an RS485 output as normal, but it may also be offered with an extra analog current or voltage output (0/4…20 mA or 0…5, 0..10 V output). Additionally, the BAROsense gives a combination of the three parameters—pressure, temperature, and relative humidity—if the optional input for the combined temperature and humidity probe is employed.

The measurements may be transmitted across great distances because of the digital output. Furthermore, because the sensor is factory calibrated at numerous sites and has great temporal stability and repeatability, the pressure transmitter may be linked to already-existing sensor networks. BAROsense can also be equipped with an LCD display for direct data reading. Additionally, the barometer transmitter is offered with a static port and support bracket as options (BAROsense…K).
