IS220SRTDH2A热电阻（RTD）输入模块 厦门海通

功能特点

• 高精度测量：能对热电阻传感器信号进行高精度测量，可精确感知温度的微小变化。这对于那些对温度控制要求严格的工业过程十分关键，比如化工生产中，精确的温度测量有助于确保化学反应按预期进行，保证产品质量。
• 多通道输入：通常具备多个输入通道，可以同时连接多个热电阻传感器，实现对多个位置温度的同步监测。例如在大型电力变压器中，可同时监测不同绕组、铁芯等部位的温度，及时发现潜在的过热故障。
• 信号调理与线性化：对热电阻传感器输出的非线性信号进行调理和线性化处理，使输出的温度值与实际温度呈线性关系，方便控制系统进行准确的温度控制和显示。
• 电气隔离：各输入通道之间以及输入与系统之间都有良好的电气隔离，能有效防止信号干扰和电气故障的传播，提高系统的稳定性和可靠性。比如在复杂的工业电磁环境中，可避免外界干扰对温度测量结果的影响。
• 故障诊断：具备自我诊断功能，可实时监测模块自身和传感器的工作状态。一旦检测到故障，如传感器断路、短路等，会及时发出报警信号，并将故障信息反馈给控制系统，便于维护人员及时处理。

技术参数

• 输入通道数：一般有 8 个或更多的输入通道，可根据实际应用需求灵活配置。
• 输入类型：支持多种类型的热电阻传感器，如 Pt100、Pt1000 等，能适应不同的温度测量范围和精度要求。
• 测量精度：测量精度较高，通常可达 ±0.1℃或更高，能满足大多数工业应用的精确温度测量需求。
• 采样速率：采样速率较快，可快速采集温度数据，一般每秒能完成多次采样，确保及时捕捉温度变化。
• 工作温度范围：可在较宽的温度范围内正常工作，例如 -40℃ 至 +85℃，适应不同的工业现场环境。

应用领域

• 电力行业：在发电厂、变电站等场所，用于监测发电机、变压器、开关柜等设备的温度，保障电力设备的安全稳定运行。
• 石油化工：在石油开采、炼油、化工生产等过程中，对反应釜、蒸馏塔、换热器等设备的温度进行实时监测和控制，确保生产过程的安全和产品质量。
• 冶金工业：在钢铁、有色金属冶炼等行业，监测熔炉、加热炉、连铸机等设备的温度，优化生产工艺，提高产品质量和生产效率。
• 食品饮料：在食品加工、饮料生产等过程中，对烘焙、发酵、杀菌等环节的温度进行精确控制，保证食品的品质和安全。
