Float and level sensors are instruments used to measure the level, volume and/or density of liquids or solids within process and storage vessels. The SSF67A25B175PM12 is one of these instruments and has a specific application field and working principle. This passage will discuss the application field and working principle of the SSF67A25B175PM12.

The SSF67A25B175PM12 is capable of measuring liquid levels in tanks and vessels up to 25 meters in height. It is particularly suitable for safe and reliable measurement in highly aggressive media. Such media includes hydrofluoric acid and caustic soda with temperatures up to 85°C. The SSF67A25B175PM12 distinguishes itself in terms of its immune to mechanical impurities. This makes it an excellent choice for rugged industrial and process applications.

The SSF67A25B175PM12 works according to the float construction principle. It is equipped with two electrodes (metal and insulated) inside a stainless steel tube-shaped float and anchored by two counterweight-capable anchors connected to a rotating arm. The rotating arm turns freely and when the level of the liquid changes, the float follows to either side in the tube. This is then monitored and reflected via the attached electrodes.

Other components of the SSF67A25B175PM12 floating level sensor are the detector, the pulse frequency converter, the mechanical gap-bridging and the effector. The detector collects the signal generated by the electrodes and the pulse frequency converter measures this signal by changing the frequency. This helps to prevent signal drift and makes the contrast between the upper and lower limit values even more pronounced. Next, the mechanical gap-bridging will use the measured signal to transfer more powerful signals from the pulse frequency converter to the effector.

The effector is a probe, which is linked to a float. This float gives out a powerful output signal to the controller once the liquid level rises to a certain point. This allows the controller to either switch on or off. The controller may also be triggered by a vacuum trip switch which will be set at the water-in level.

Therefore, the SSF67A25B175PM12 is an industrial float level sensor suitable for measuring liquids up to 25 meters in height. It operates based on the float construction principle and provides a powerful output signal to the controller with the help of the effector. Additional components such as the detector, the pulse frequency converter and the mechanical gap-bridging provide a reliable performance each time.
