SSF67A50A250 application field and working principle

The SSF67A50A250 is a float-type level sensing device of the Submersible Sanitary Flow Level Switch family. It detects the level of liquid in a variety of applications, such as tank and process level monitoring, high level detection, low level detection, empty tank detection and overfill protection. Its low-cost design provides an economical level detection option for areas where remote cable entry is not possible or where conduit connection is not feasible.The SSF67A50A250 float is formed from PTFE material and is supported by a state-of-the-art nylon core rod that has a maximum diameter of 0.5 inches (12.5mm). The float is clamped by a compression fitting which is secured to the main body. The SSF switch is connected to the float with a stainless steel tube, which is then sealed with a leak-proof silicone o-ring. The float is also encapsulated to ensure it remains protected from the harmful effects of prolonged contact with liquid.The SSF switch is a mercury-free device that utilizes a combination of a spring-loaded switch and a non-metallic diaphragm as the contact surfaces. This combination provides a highly reliable level sensing capability that is unaffected by corrosive and conductive liquids. The spring-loaded switch’s travel can be adjusted by turning the adjusting screw on the top of the main body. This movement causes the switch point to travel from the differential level of the operation point to the low or high level.The SSF switch is designed to be used under any liquid application temperature condition. It maintains its accuracy and repeatability from -40°F (-40°C) to 115°F (45°C) with the exception of hydrocarbon-, alcohol-, or chlorine-based fluids for which a special request is needed. The operating pressure of the SSF switch is normally atmospheric but can be customized up to a pressure of 6 bar.The SSF switch is equipped with an on/off indicator that is activated by the float’s movement. The indicator can also indicate if the switch is activated even if the float has not yet reached the end point. The SSF switch can also be fitted with an additional pneumatic indicator, which can alert the host process of the switch’s status.The SSF switch is designed with a wide variety of mounting procedures to suit a multitude of applications. It can be topped, the shell can be mounted, it can also be perpendicularly mounted, and even partially submerged installation is allowed. In conjunction with its wide range of accessories, the switch can be equipped with additional floats, probes, or dampeners; allowing it to adapt to a wide variety of installation needs and operation conditions. In conclusion, the SSF67A50A250 provides an economical and reliable choice for all types of liquid level sensing applications. The switch is designed with a wide combination of installation options, and its reliability and accuracy are second to none. With a variety of accessories and mounting procedures, it can be used in applications where other float level switches may not have been practical. The SSF67A50A250 is the perfect solution for a variety of liquid level sensing needs.
