The rugged Fluke 831 has an intuitive guided user interface that enables quick and complete shaft alignment without advanced training or complicated programs. And while it’s easy to use, laser alignment with the Fluke 831 is powerful enough for the skilled technician. You can cover more of your machines with all the functionality needed on the plant floor, from thermal growth to user defined tolerances and more.

Misalignment causes at least half of all damage to rotating machinery, studies show. Instead of fixing the problem, teams often just treat the symptoms of misalignment and replace bearings, couplings, and seals because they think alignment takes too long.

For control of ordinary purified water or sewage water . 

Supply voltage: 100, 110, 120, 200, 220 or 240 VAC; 50/60 Hz 

Operating voltage range: 85% to 110% of rated voltage 

Ideal for level control of any conductive liquid Both general-purpose and panel-use models available Incorporates an arrester for surge and induced lightning protection Wide range of models: Long-distance, high- and low-sensitivity, two-wire, etc. LED indicator for quick operation check Conforms to EMC/IEC standards (61F-GP-N/-N8/-GPN-V50) UL/CSA approved (61F-GP-N8/-GPN-V50)

A pump is usually connected to a contactor, which in turn is connected to the Controller contact outputs. The Level Controller would automatically operate the pump, to control the liquid level in the tank. However, in practice, with only two electrodes, ripples on the surface of the liquid cause the Controller to jump and start, shortening pump (and other equipment) life. This problem can be solved by adding another electrode to form a self-holding circuit. The additional electrode, E2, is connected in parallel with E1, as shown below.

Unlike ordinary level switches that use a float for level detection, the 61F Floatless Level Controller uses electrodes to electrically detect the liquid level. The following figures illustrate this simple operating principle.

Relay contacts a E1 Magnetic contactor (To) E3 No current flows between E1 and E3.


When electrode E1 is not in contact with the conductive liquid, the electrical circuit is open, and no current flows between electrodes E1 and E3. Consequently, relay X does not operate. Relay X's NC contacts (normally closed, b in the figure) remain closed. However, when liquid is supplied to the tank, so that the liquid contacts or immerses E1, the circuit closes. Relay X operates, and electrical devices connected to the NO (normally open, a in the figure) contacts of the relay begin operation.

Relay contacts a E1 Magnetic contactor (To) E3 Current flows between E1 and E3.


As shown in the above figure, when the holding circuit relay is energized, contact a2, its NO contact, is closed. The electrical circuit made through the liquid and the electrodes is then retained by E2 and E3, even when the liquid level falls below E1, as long as contact a2 is closed. When the liquid level falls below E2, the circuit made through the electrode circuit opens, which de-energizes relay X, thus closing the NC contact of X. Operating as simply as it does, possible applications of the Floatless Level Controller are virtually endless. Not only liquid level control is possible, but such applications as leakage detection, object size discrimination, and many other problems may be solved by one of the reliable 61F Floatless Level Controllers.

To use a 61F Conductive Level Controller, the 61F itself, Electrode Holders, and Electrodes are required.

Select from the capability, function, and size to suit the application. 61F Refer to the following Controller selection guidelines. Basic configuration Electrode Holders Select from the characteristics, application examples, and shape. Refer to page 66 for cautions about the Electrode Holders. Select according to operating conditions and shape. Electrodes Refer to pages to 67 for cautions about the Electrodes.

A pump is usually connected to a contactor, which in turn is connected to the Controller contact outputs. The Level Controller would automatically operate the pump, to control the liquid level in the tank. However, in practice, with only two electrodes, ripples on the surface of the liquid cause the Controller to jump and start, shortening pump (and other equipment) life. This problem can be solved by adding another electrode to form a self-holding circuit. The additional electrode, E2, is connected in parallel with E1, as shown below.
Unlike ordinary level switches that use a float for level detection, the 61F Floatless Level Controller uses electrodes to electrically detect the liquid level. The following figures illustrate this simple operating principle.
Relay contacts a E1 Magnetic contactor (To) E3 No current flows between E1 and E3. 

When electrode E1 is not in contact with the conductive liquid, the electrical circuit is open, and no current flows between electrodes E1 and E3. Consequently, relay X does not operate. Relay X's NC contacts (normally closed, b in the figure) remain closed. However, when liquid is supplied to the tank, so that the liquid contacts or immerses E1, the circuit closes. Relay X operates, and electrical devices connected to the NO (normally open, a in the figure) contacts of the relay begin operation.
Relay contacts a E1 Magnetic contactor (To) E3 Current flows between E1 and E3. 

As shown in the above figure, when the holding circuit relay is energized, contact a2, its NO contact, is closed. The electrical circuit made through the liquid and the electrodes is then retained by E2 and E3, even when the liquid level falls below E1, as long as contact a2 is closed. When the liquid level falls below E2, the circuit made through the electrode circuit opens, which de-energizes relay X, thus closing the NC contact of X. Operating as simply as it does, possible applications of the Floatless Level Controller are virtually endless. Not only liquid level control is possible, but such applications as leakage detection, object size discrimination, and many other problems may be solved by one of the reliable 61F Floatless Level Controllers.
