HTabsOverview Part number: 3.1157.10.xxx Scalable: measuring range, analogue output Configurable: mean value calculation, heating control, energy saving mode, baud rate. The baro transmitter measures the “absolute air pressure” of the atmosphere at the site. It is designed for application in the field of environmental protection, where high accuracy, quick responding behaviour, long-term stability and reliability are required. The instrument is suited for in- and outdoor application. A tempered piezo-ceramic sensor for absolute pressure is used, which is characterized by thermal and mechanical stability. The electric connection is done via an 8-pole terminal strip and a special screwed cable gland with smoothing function for air pressure. The following outputs are available:1 x serial interface1 x frequency output1 x analogue output (U/I) Baro Transmitter - 3.1157.10.xxx_.pdf SpecificationMeasurement Parameter: Barometric PressureSpecification: Part number: 3.1157.10.xxx Air pressure Measuring range 260 ... 1260 hPa Accuracy with heating± 0,25 hPa @ -40 ... +65 °C @ 800 ... 1100 hPa± 0,50 hPa @ -40 ... +65 °C @ 600 ... 800 hPawithout heating± 1 hPa @ -40 ... +65 °C @ 600 ... 1100 hPa Long-term stability ± 0.3 hPa / Year Data output digital Output type RS485 andImpulse output Operating voltage Electronic 5 ... 24 V DC ( for digital outputs only) otherwise12 ... 24 V DC Current consumption 10 mA max. @ 12 V Heating 12 ... 24 V DC, max. 115 mA @ 12 V General Ambient temp. -40 ... +65 °C Electr. connection terminal strip Dimension 110 x 82 x 57 mm Weight 0.15 kg Further InfoDocuments: Baro Transmitter - 3.1157.10.xxx_.pdf
