When you need a durable way to monitor the levels of harsh substances in a tank, use this float switch from Sensata Cynergy3. Thanks to its polyvinylidene fluoride construction, it's resistant to chemicals, heat and abrasion, making it suitable for use in heavy-duty applications. It's compatible with fluids that have a minimum specific gravity of 0.85, so you can use it with water as well as common oils and acids. This float switch is commonly used in vending, printing and chemical dosing applications.

• Wide operating temperature range of -10°C to +105°C for use in demanding environments
• Switching current of 600mA for energy efficiency
• Mounts on the top or bottom of a tank for use in situations where there's no side access
• Cable length of 1m for a flexible electrical connection

This float switch has a normally open configuration. However, it's simple to change the configuration to normally closed by removing the float from the stem and rotating it 180°, making it a versatile choice.
