Optical sensors, tilt-float switches & conductivity switches ideal for use with semi-solid liquids, slurries or oil in high / low level alarm triggers, overflow or spill containment vessels and pumps. Feature a polypropylene / EPDM float that can withstand a max. temperature of 221 degrees F
Continuous-level ultrasonic sensors providing non-contact fluid level measurement of semi-solid, viscous & corrosive media in close / open channel flows. Feature a self-cleaning sensor face with the capacity to filter out false echoes & a temperature compensated signal for better accuracy
The company's product catalogue includes switches, floats, indicators and sensors. Madison float switches are used to measure liquid levels using sensors with an electrical contact output. They are also available in optical & conductivity sensor variants that can withstand extreme temperatures, pressures and vibrations. Liquid level switches by Madison feature a high-level alarm and are used in liquid control systems to prevent the spill & overflow of fluids. The brand's tape level indicators use a magnetic float to read liquid level. They are widely used in drums and storage tanks.
They are designed for monitoring dispensed agricultural fertilisers & high-value chemicals, tank level monitoring and lubrication applications. These sensors are capable of fitting into small tanks (4 - 5 inches). The compact physical dimensions of the float & stem and small deadband take little space in the tank, leading to more usable tank volume.
Madison stock float switches are accurate within 1/8 inches of the centre of the float travel, with a hysteresis of 1/16 inches. Every switch can switch repeatably within 1/32 inches.
In most applications, a relay is needed for isolating float switches from the device. The float switch is connected in series with a relay input coil that draws current less than 500mAs the switch is closed, the relay coil gets activated and shuts the output contacts. These contacts turn the high current ON or OFF as per the device requirement.
Consider factors like the type of substance being measured, the measurement range, environmental conditions, required accuracy and the specific industry requirements.
Yes, Madison switches can be configured to trigger alarms for both high and low liquid levels. This dual functionality is valuable for applications where maintaining levels within a specific range is critical.
