Put Level Switches to Work for Your Jobs


If your current profession involves the need for specialized parts, where do you go to find them?

While many consumers would turn to stores in their neighborhoods or vendors that they know of, others opt for the Internet. As online sales of countless items continue to increase, going to the worldwide web for both information and ultimately purchasing products is becoming the norm.

That said using the Internet for research and buying parts you will require for a job in the home, a construction and/or worksite etc. makes sense.

One of those needs may be a level switch.

For those not entirely sure what these are, level switches essentially come and work in three different configurations.

First, a NLS pneumatic level switch works to gather a section of trapped air. When the liquid level goes upward, the air is contained in a pipe connected at the end of a sensor. With the level increasing to a degree, the air is compressed inside the pipe. This then alerts a mechanical switch inside the housing.

Meantime, a PWS paddle wheel switch will spin on its own up to the point where the solid material is amassed to the full point of stoppage. Once the wheel has completed its rotations, the level switch is then activated. These types of switches are oftentimes rather inexpensive, along with the fact that they

Lastly, a VBL vibrating level switch works much like the paddle wheel, however it does not spin a wheel. It ultimately ends up vibrating a rod. These types of switches also do not require calibration, plus they are generally simple to install and set up.

Be Prepared to Ask an Expert

In shopping for the right level switches for your needs, come up with a list of questions to clarify any information you’re not sure of.

Many companies selling level switches and related products will provide myriad of information on their websites to help the user better understand the items.

For example:

  • Is power always required to put in a level switch? Yes. Your float switch requires a signal current so that it can properly operate.
  • How best can you mount a switch? Both the PWS and VBL are able to mount both at horizontal and vertical angles. Meantime, the NLS should be mounted on the top of a tank.
  • Will level switches operate in locations with hazards? They will. It is best to make it out to be a simple apparatus, making sure it has the right intrinsic safety barrier or isolator in hand.

Locations to Use Level Switches

Depending on the job at hand, level switches can prove to be just what you were looking for in making sure any major onsite appliances (water tank etc.) are working properly.

These items are oftentimes used in locations such as sewers and water works for both commercial and residential housing, water treatment and sewage treatment plants etc.

If you have a water tank that you want to monitor regularly, your level switch will oversee the pressure inside, allowing you to know when a pre-determined level setting has been attained. Once that occurs, a message is transmitted from the level switch to another apparatus, oftentimes a pump or valve actuator. At the end of the day, this will help you in preventing problems such as leaks and/or flooding.

In the event you are in need of level switches, take the time to do some online research, noting which ones are best suited for your job requirements.

By doing that, you will be better informed and better suited to meet the needs of the job at hand.
