Standex Electronics fluid sensors provide more than just an on/off signal. Our fluid sensor solutions use a wide range of switching technologies - from magnetic reed switch technology to conductive and hall effect technology. A single PCB with many reed switches can provide multi-level measurements. But that's not all. We're experts in delivering smarter solutions to the most demanding fluid level sensing applications. These include basic fluid sensors driven by external electronics to turnkey sensor systems with discreet voltage outputs. Our fluid sensor designs include single, multi, or continuous level output. They can include custom packaging and header designs as well as integrated hermetic connectors.
Standex Electronics advanced fluid level sensors are custom design solutions utilizing Hall Effect or Capacitive sensing technologies for continuous liquid level monitoring. They offer long term solid state reliability over a wide temperature range as well as custom programable outputs with many packaging and mounting options...
Our liquid level sensors with integrated magnetic floats and cable terminals are used to detect low fluid levels or multiple fluid points. Choose from vertical or horizontal mount options and a range of switching options. They are simple, dependable, versatile, and low cost. Easily customizable and simple to install, magnetic level sensors are low power devices that don’t require electronics, making them very appealing for most applications. Reed liquid level sensors are fast...
Horizontal Mount Liquid Level Sensor products can be mounted on the side of the liquid reservoir or vessel using their hardware either internally or externally...
Standex Electronics Flood Prevention Switches (FPS) HVAC/R series are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Utilizing proven expert magnetic reed switch technology that feature Low voltage switching and reliable “no-stick” float design so...
Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents...
In multiple or continuous level sensor products, 100's of sensing points are possible. Information can be signaled with simple magnetic reed switches by mounting many reed switches to a PCB to give multiple liquid level point measurements. In this application resistors can be placed in circuit to provide discreet voltage outputs that will indicate one of many possible level points along the travel path of a magnetic float for continuous liquid monitoring...
A single level fluid sensor has a single magnetic float that moves with the changing level of a fluid and measures either a critical low level of fluid or other single fluid level...
SPDT changeover reed switch products are a single (Form C) reed switch which is essentially a single pole double throw SPDT reed switch. It is hermetically sealed with 3 leads: a common lead, a normally open lead, and a normally closed reed switch lead. When operated the common contact will swing from the normally closed contact to the normally open contact. This is caused by the magnetic field produced by a coil or the magnetic field from a magnet. When the magnetic field is ...
A Form B Fluid Sensor contains a single pole single throw, normally closed (SPST-N.C.) reed switch. It's contacts are the normally closed (Form B) position before any magnetic field is applied. Fluid sensors and floats can be configured to function as a normally closed or Form B reed switch. A Form B fluid sensor containing a normally open reed switch that uses it's floating magnet to keep it in the closed position, as with our horizontal mount LS03 series Liquid Level Sensor. Check out...
A SPST-N.O. (1 Form A) reed switch has it's contacts in the open state before any magnetic field is applied, drawing no power...
A vertical mount liquid level sensor has one or more floats and can be mounted vertically to the top or bottom of liquid tank or reservoir...
