Capacitance probe switches are rod-shaped sensors that provide point level measurement of liquids, slurries, and pastes. Once installed, the sensors and vessel serve as the two electrodes that form a capacitor, and the media inside the vessel represents the dielectric. The radio frequency signals produced by the capacitance point level switch calculate changes in current and transmit them as an output signal.
Most capacitance point level switches are made of stainless steel and can withstand high temperatures and corrosive environments, making them ideal for use in chemical applications.
Mechanical float switches are mechanically actuated float sensors used for point level measurement of corrosive and non-corrosive liquids and slurries. When fluid levels rise to a specified level, the mechanical float switch may automatically trigger a pump or valve that remains on until the fluid returns to the desired level.
The sensors are often installed at two different levels to prevent overflow in the event the first pump fails. Mechanical float switches are commonly used for point level measurement of water and wastewater. Our inventory includes corrosion-resistant mechanical floats from Gems and Dwyer.
