描述
投入式测量传感器是特别为液位测量而开发的。 由于浸润部分系统地采用不锈钢制造,因此该传感器可以毫无限制的是用于食品工业。如果进行腐蚀介质的测量,则有另一款带有 PTFE 电缆的型号。 该传感器有密封的不锈钢外壳,防护等级为 IP 68,可以在水下300米处使用。 内部通风连接的电缆可以补偿测量单元与大气之间的压力差,这样就可以实现流体静压测量了。 固定压力传感器不需要任何额外的张力缓解,因为电缆的结构能够承载最大张力达 1000N。通过螺栓可以固定额外重物来增加传感器的重量。 传感器独立于主电源工作,可以在6伏的供电电压下运行。 T该传感器可以配备避雷保护。它还装可以装备一个 PT 100 传感器来测量介质温度。 投入式压力传感器满足 EN 61326 的电磁兼容性(EMC)要求。
