适用 CIP 和 SIP 0.20% 满量程精度 膜片无需充液 890 系列符合 3A 卫生设计标准，全密封的结构可承受外部的高冲洗压力。传感器封装于不锈钢外壳内，对冲击、振动等恶劣环境极不敏感。tri-clover 型卫生压力接口允许传感器直接以 CIP、SIP 方式安装。其他部件包括先进集成电路、1/2” NPT 电缆套管和带排气管的屏蔽电缆线。电位器实现零满调整。 应用： 食品加工 乳制品及饮料加工 医药 卫生管路
For Clean-In-Place (CIP) and Sterilize-In-Place (SIP) 0.20% Full Scale Accuracy No Liquid Fill Diaphragms
The 890 Series meets 3A sanitary design standards and is fully sealed to withstand external high pressure washdowns. These units are packaged in rugged welded stainless steel housings and are exceptionally insensitive to vibration, shock and environmental extremes. A small size and tri-clover sanitary pressure fitting allow direct mounting in most CIP and SIP installations. Other features include IC-based circuitry, a 1/2” NPT conduit fitting and shielded cable with vent tube. Sealed screws provide access to zero and span adjustments.
