PROFIBUS® temperature transmitter as head or field device with two universal sensor inputs suitable for use in hazardous areas. 2 input channels and PROFIBUS® PA protocol for the conversion of input signals into digital output signals. The device stands out due to signal reliability, long-term stability, high precision and advanced diagnostics (important in critical processes). For the highest level of safety, availability and risk reduction. Installation in flat-face terminal head as per DIN EN 50446. Optional installation in field housings even for use in Ex d areas – with mounting brackets for wall or pipe mounting.
Benefits
- Easy and standardized communication via PROFIBUS® PA Profile 3.02
- Meets the EMC requirements as per NAMUR NE 21 and the recommendations of NE 89 with regard to temperature transmitters with digital signal processing
- Straightforward design of measuring points in Ex-areas through FISCO/FNICO conformity in accordance with IEC 600079-27
- Safe operation in hazardous areas thanks to international approvals such as FM IS, NI, CSA IS, NI as well as ATEX Ex ia, Ex nA (Ex nL)
- High accuracy through sensor-transmitter matching
- Reliable operation with sensor monitoring and device hardware fault recognition
