Sensata Cynergy3 SSF67 Series Vertical Stainless Steel Float Switch, Float, 1m Cable, NO/NC, 250V ac Max, 120V dc Max

Need a multipurpose solution for your liquid tank applications? Choose this versatile float switch from Sensata Cynergy3. Its twin-switch, single-float design means you can use it to alert you to high and low liquid levels for ease of monitoring. Thanks to its stainless steel body, this robust component is resistant to corrosion and wear. M16 threads and washers provide secure, leakproof mounting, helping to ensure accurate level sensing. You'll find this float switch used in applications from food and beverage production to the petrochemical industry.

• Cable length of 1m for a flexible connection between your control module and the power supply
• Mounts at the top or bottom of the tank for use in setups with no side access
• Compatible with fluids that have a minimum specific gravity of 0.8 for versatility
• ETFE cable sheath withstands high temperatures for safety in harsh environments

This float switch has a wide process temperature range between -20°C and +135°C, so it's suitable for use in demanding applications.

• Two Independent Switching Points
• Maximum temperature 135 °C
• Minimum Fluid SG(Specific Gravities): 0.80
• Suitable for high and low level alarm and control signal
• Manufactured in Stainless Steel 316L material

One of the most reliable, well-demonstrated technologies for fluid level detecting is float switch. This sort of switch involves a magnet contained inside a float, and also an attractive reed switch contained inside a settled housing. The movement of float, due to changing fluid level, will cause the reed change to work (for instance close or open) at specific level. This trusted and tried technology depends on a generally straightforward plan that offers long haul quality without the requirement for the client to calibrate a switch.

There are different methods available how to choose a float switch for particular application, here are the main factors to consider:

The choice of styles depends on the physical arrangement of the tank, availability of mounting positions and whether there is an access inside of the tank.
Fundamental styles are horizontal / side mounting and vertical mounting. Horizontal / side mounting has a fixed housing, which you can find on the wall of a tank and it has got a hinged float attached to the fixed housing. Vertical usually have a fixed vertical stem and that is installed at the top or bottom of the tank.

It is very important to choose a float switch that is made from right materials, which are compatible with the liquids and temperatures of the chosen application. While using incorrect material it can resolve in damaging of the component as well as failure of a float switch.

• Nylon – used for oils, diesel, organic chemicals and MEK (methylethylketon) based printing inks
• Polypropylene (PP) – acids and alkali, detergents, oils, water, organic chemicals
• Polyphenylene sulphide (PPS) – used for more aggressive chemicals, and higher temperatures, up to 120ºC
• Stainless steel – medical and food industries, hydraulic fluids, chemicals, and environments with high temperatures up to 135ºC
• Buna/Nitrophyl – diesel, oil, petrol and water (stationary applications)
• D300 foam (PVC) – mostly for hydraulic oils and chemical solutions

You need to fully understand what is the nature of the load that requires to be switched and make sure that the float switch is adequate for holding your load. The electrical ratings, which we provide in specifications are resistive loads.

In areas where harsh liquids may spill onto external wiring, it is important to underline particular materials for the cables in connection to the float switches. You can either use standard, UL-approved cable types for the range of float switches, as well as high temperature, low smoke zero halogen (LSZL) and other specialised materials.

The SSF67A25B300 has been designed to give user a long reach float switch with a number of switching options, to cater for a wide variety of system requirements such as aggressive liquids, hygienic applications, petrochemical, storage and process control applications.

The cable entry point must NOT under any circumstances be submerged.
