适用空气及非导电气体 0.25 至 100 英寸 (6.35 至 2540 mm) W.C. (差压)/±0.1 至 ±50 英寸 W.C. (双向) 高过压能力 865 系列微差压传感器量程最低支持 0.25" (6.35 mm) W.C.，同时具有±1% 满量程精度。针对楼宇能源管理系统，865 系列可以为楼宇增压及空气流量控制提供合适精度的压力、流量测量。865 系列采用全不锈钢微型惰性气体 TIG 焊接，可以承受最高 10 psi (0.69 bar) 过压(任意方向) 而不会损坏。传感器元件均进行温度补偿，提高了温度性能及长期稳定性。 应用： HVAC 能耗管理系统 变风量 VAV 及风扇控制 环境污染控制 静态管路及洁净室压力 炉膛压力及风量控制
For Air or Non-Conductive Gas 0.25 to 100 Inches in W.C.(differential)/ ±0.1 to ±50 Inches in W.C. (bidirectional) High Proof Pressure
The 865 Series are very low-pressure transducers for ranges as low 0.25˝ W.C. and feature ±1% full scale static accuracy. Primarily used in Building Energy Management, these transducers are capable of measuring pressures and flows with the accuracy necessary for proper building pressurization and air flow control. 865 Series transducers utilize an all-stainless steel micro-tig welded sensor that allows up to 10 psi overpressure (in either direction) with no damage to the unit. All sensor components have thermally matched coefficients, which promote improved temperature performance and excellent long-term stability.
