What is a water level sensor?
What is a water level sensor? The water level sensor is a device that measures the liquid level in a fixed container that is too high or too low. According to the method of measuring the liquid level, it can be divided into two types: contact type and non-contact type. The input type water level ...Read more -
A Brief History of the Reed Switch
A reed switch is an electrical relay operated by an applied magnetic field. While it may just look like a piece of glass with leads protruding from it, it is an intensely engineered device that works in amazing ways with customization methods employed for their use in many applications. Nearly al...Read more -
Reed Switches and Hall Effect Sensors
Reed Switches and Hall Effect Sensors Reed Switches and Hall Effect Sensors Magnetic sensors are used in everything from cars to cellphones. What magnet should I use with my magnetic sensor? Should I use a Hall effect sensor or a reed switch? How should the magnet be oriented to the sensor? What ...Read more -
Reed Switch
Reed Switch A reed switch is a passive device consisting of two Reed Blades sealed inside a glass tube with an Inert Gas, which operates when brought near a magnetic field. The reeds are hermetically sealed in cantilever form so that their free ends overlap and are separated by a small air gap. T...Read more -
Reed Sensors vs. Hall Effect Sensors
Reed Sensors vs. Hall Effect Sensors Hall Effect sensors also use the presence of magnetic force to power the opening and closing of a switch, but that’s where their similarities end. These sensors are semiconductor transducers that produce a voltage to activate solid-state switches rather than s...Read more -
About Reed Sensors
About Reed Sensors Reed sensors use a magnet or electromagnet to create a magnetic field that opens or closes a reed switch within the sensor. This deceptively simple device reliably controls circuits in a wide range of industrial and commercial goods. In this article, we’ll discuss how reed sens...Read more -
What is a Reed Switch and How Does it Work?
If you visit a modern factory and observe the amazing electronics at work in an assembly cell, you’ll see a variety of sensors on display. Most of these sensors have separate wires for positive voltage supply, ground and signal. Applying power allows a sensor to do its job, whether that’s observi...Read more -

How to replace a defrost heater in a side-by-side refrigerator
This DIY repair guide gives step-by-step instructions for replacing the defrost heater in a side-by-side refrigerator. During the defrost cycle, the defrost heater melts frost from the evaporator fins. If the defrost heater fails, frost builds up in the freezer, and the refrigerator works less ef...Read more -
Top 5 Reasons Why a Refrigerator Won’t Defrost
There once was a young man whose very first apartment had an old freezer-on-top refrigerator that required manual defrosting from time-to-time. Not being familiar with how to accomplish this and having numerous distractions to keep his mind off this matter, the young man decided to ignore the iss...Read more -
What causes defrost problem in a refrigerator?
the most common symptom of defrost problem in your refrigerator is a complete and uniformly frosted evaporator coil. Frost may also be seen on the panel covering the evaporator or cooling coil. During the refrigeration cycle of a refrigerator, moisture in the air freezes and sticks to the evapora...Read more -
How to Install a Refrigerator Defrost Heater
A frost-free refrigerator utilizes a heater to melt the frost that can accumulate on the coils inside the freezer walls during the cooling cycle. A preset timer typically turns on the heater after six to 12 hours regardless if frost has accumulated. When ice begins to form on your freezer walls, ...Read more
