壓力變送器3051是為流程工業應用所設計,可以測量液體、蒸汽和氣體的壓力。采用全球**高精度硅技術,保證傳感器的高穩定性和高可靠性。
壓力變送器3051是一款電池供電、具有無線通訊功能的高精度智能變送器。應用領域是針對野外或配套供電環境不便的場合,如輸油,輸汽,供暖等輸送能源管道等地方進行壓力監測,實現信號無線遠傳。配合無線通訊接收模塊使用,上位機可直接使用組態實時監測采集數據。
特點:
1、采用世界先進的隔離技術,具有超強的抗干擾性能
2、采用全球**高精度硅技術,獨特的雙過載保護膜片設計,單向過壓*高可達60MPa
3、高精度,精度優于0.1%
4、高穩定性和高可靠性
5、完善的自診斷及遠程通訊功能
6、可選擇HART協議或rs485通訊協議
7、電池供電使用時間長
