Float Switches from WIKA

Reliable Point Level Switching for Industrial Applications

Float Switches from WIKAWIKA float switches provide dependable point-level detection for liquids across a wide range of industrial processes. Designed for durability, accuracy, and long service life, these mechanical level switches operate independently of power supply for sensing, making them ideal for safety-critical and harsh environments. Valin offers WIKA float switch solutions engineered for chemical processing, oil & gas, water treatment, power generation, food & beverage, and general industrial applications.

Features

Overview & Features

WIKA float switches are mechanical level switches that detect liquid level based on buoyancy. As the liquid rises or falls, the float moves along a guide tube or pivot arm, actuating one or more internal reed contacts. This simple operating principle delivers exceptional reliability with minimal maintenance.

Key Features

  • Mechanical operation with no continuous power required for sensing
  • Stable switching independent of density, conductivity, foam, or turbulence
  • Suitable for clean and contaminated liquids
  • Long service life with proven reed switch technology

Common Functions

  • High-level and low-level alarms
  • Pump and valve control
  • Overfill protection
  • Dry-run prevention

Float Switches Q & A

    + What liquids can WIKA float switches be used with?
WIKA float switches are suitable for a wide range of liquids, including water, oils, chemicals, fuels, and process fluids. Material selection ensures compatibility with corrosive or high-temperature media.
    + Can one float switch monitor multiple level points?
Yes. WIKA multi-point float switches can incorporate several switching contacts on a single stem, allowing multiple alarms or control functions within one instrument.
    + Are WIKA float switches safe for hazardous areas?
Yes. WIKA offers float switches with intrinsically safe and explosion-proof designs that comply with relevant hazardous-area standards, making them suitable for oil & gas and chemical environments.
    + How accurate and reliable are float switches compared to electronic sensors?
Float switches provide highly reliable point-level detection with excellent repeatability. Because they operate mechanically, they are unaffected by conductivity, foam, vapor, or electrical interference.
    + How do I choose the right float switch for my application?
Key factors include tank size, mounting location, liquid properties, temperature, pressure, and required certifications. Valin application engineers can assist in selecting and configuring the correct WIKA float switch.
