What is Low Smoke Zero Halogen?

What is Low Smoke Zero Halogen?  Low Smoke Zero Halogen is also known as LSZH. And low smoke zero halogen materials are used in place of PVC materials where fire conditions pose a significant risk to life and equipment. These cables do not produce halogen acid gases when burned and do not release the significant layers of dense black smoke of PVC equivalent materials in the event of a fire. Various additives can be added to this material to improve its resistance to chemicals, including oils and solvents. Silicone rubber is used in applications where an extended temperature range is required, suitable for applications from -90°C to 180°C. And silicone rubber is also widely used where cables are required to maintain circuit integrity under fire conditions.

What is cross-linking polyethylene?

What is cross-linking polyethylene?  Cross-linking polyethylene is also known as XLPE. And cross-linking improves PE cable performance, increasing temperature and chemical resistance. Cross-linking polyethylene materials are mainly used as insulation materials.

What is Polyethylene?

What is Polyethylene?  Polyethylene is also known as PE. and is used as either insulation or cladding material. It has excellent chemical resistance including oils and very low water absorption. Polyethylene also has excellent mechanical strength and low-temperature resistance. Due to the stiffness of the PE material, PE cables are somewhat rigid and not flame-resistant. Because of its flammability, PE sheathing is typically used for outdoor applications or with cables for direct burial.

What is Polyvinyl Chloride?

What is Polyvinyl Chloride? Polyvinyl chloride is known as PVC. And is flame retardant and self-extinguishing. and is used either as an insulation material or as a cladding material. PVC is an extremely versatile material that has traditionally been used extensively in the cable industry. PVC can be modified for both indoor and outdoor use, in both wet and dry conditions, conduit or direct burial, and high- and low-temperature applications. PVC also has resistance to various chemicals, including some oils and solvents. PVC is being replaced by low-smoke, halogen-free materials in certain applications, where fire conditions pose a greater risk to life and equipment.

What materials are used in instrumentation cables?

What materials are used in instrumentation cables?   Materials commonly used in instrumentation cable design are PVC, PE, XLPE, LSZH, mica tape, steel wire armouring, metal braid and lead alloy sheath.

What is an optical level switch?

  What is an optical level switch? Optical level switch Optical level switches are basically the same as radar sensors; The difference is that optical light is emitted instead of waves. And the light is transmitted and reflected back into the conical prism structure. This means that light will not travel all the way through the medium, but will be confined within a structure. And there is no medium in this structure, then the light will be reflected back. If a medium is present, the light will not be reflected back. This changes the electrical output.

What is a paddle type level switch?

What is a paddle type level switch? Paddle type level switch Basically it's a very simple concept and works on the movement of a paddle. And below is installed in the sensor setup, which is driven by a small electric motor. In the absence of any medium, the paddle will rotate freely. If in contact with any medium, more force will be required to move the paddle. It may also happen that the pedal stops rotating. This rotational change changes the electrical output.

What is an inductive level switch?

What is an inductive level switch? Inductive level switch Basically an inductive level switch works on the principle of electromagnetic radiation and eddy currents. And it uses an oscillator resonant circuit that uses a core magnetic coil to generate a strong electromagnetic field. When this field penetrates the media, it creates eddy currents that reduce the amplitude of the oscillations. This switch changes the electrical output.

What is a vibrating fork level switch?

What is a vibrating fork level switch? Vibrating fork level switch Basically the vibrating fork level switch works on the principle of vibration. And it uses a fork that vibrates every time through an internal mechanism. When this fork comes in contact with the media, the vibration level changes. This changes the electrical output.

What is a Radar and Laser Level Switch?

What is a Radar and Laser Level Switch? Laser level switch Basically radar and laser level switches are non-contact switches that emit ultraviolet radar rays as well as microwaves to transmit and reflect waves. And the waves touch the surface of the media and are reflected back to the transmitter. It then measures the distance or height of the medium by measuring the time it takes to transmit and receive and the speed of the waves.

What is capacitive level switch?

What is capacitive level switch? Capacitive level switch Basically this switch is like a capacitor, the switch has an insulated electrode that acts as the first plate and the tank wall (reference electrode) acts as the second plate. And the capacity between the two varies with the height of the medium level. As the level changes, the capacitance changes and so does the electrical output.

What is a conductivity level switch?

What is a conductivity level switch? Conductivity level switch Basically the conductance level switch work is similar to the capacitance level switch; And the only difference is that it works on resistance. And this is similar to the probe theory mentioned earlier, the difference in resistance between them (based on the media layer) converts to electrical output. It will only work if the media has some conductivity, which causes electrical resistance.

What is Displacer Level Switch?

What is Displacer Level Switch? Displacer level switch Basically the displacer level switch works on the principle of weight displacement. And a displacer is used, which is a very heavy float type, suspended by a spring. When the media level touches the displacer and submerges it in water, due to the buoyant force and the weight of the displacer relative to the acting medium. This releases the spring pressure and changes the electrical output. This means that the weight of the displacer must be greater than the weight of the media in normal condition (when the media is not touched). Only then, it will detect the change in weight.

What is a float level switch?

What is a float level switch? Float level switch Basically float switch is the most common type of level switch. It is mounted or floating on the media to be sensed. Suppose it is floating on a liquid. When the float is in the upright position or above the upright position, it means the level is correct. Now, let's say the float goes below the vertical position. This means the level has dropped and because of this, the switch will change its electrical output. The switch consists of a magnet with a reed switch. It is the switch that transmits the electrical signal. The switch is moved by a magnet which changes its position according to the floating level sensed.

What are the types of level switches?

What are the types of level switches? Types of level switches Float Level Switch, Diaphragm Level Switch, Capacitive Level Switch, Conductivity Level Switch, Displacer Level Switch, Inductive Level Switch, Vibrating Fork Level Switch, Optical Level Switch, Radar and Laser Level Switch, Paddle Type Level Switch
