Endress+Hauser FTL51-6M6T4 Point Level Switch

Endress+Hauser FTL51-6M6T4 Point Level Switch is a sensor that provides a discrete level-detection signal at a preset point in a tank, vessel, or process line. It detects when liquid reaches the configured level and is used to drive control actions such as alarms or interlocks in automation systems. This model belongs to Endress+Hauser's FTL51 family and specifies a particular product configuration within that lineup. The FTL51-6M6T4 variant identifies the exact configuration for compatibility within the manufacturer's instrumentation ecosystem. Typical applications include single-point level detection where a defined high- or low-level condition is required to initiate a control sequence. Because it delivers a binary indication rather than continuous measurement, it is well-suited for simple logic and interlock schemes in process operations. Endress+Hauser positions this switch for integration with standard process instrumentation, offering straightforward installation and a clear on/off signal to programmable logic controllers and other automation devices.
