Sords Electric Sells the Robertshaw Industrial Products 365A Explosion Proof Vibraswitch

By Robertshaw Vibration Switches HERE.

The 365A series Vibration Switch is the standard of the industry for Vibration Detection. The Robertshaw Switch is based on acceleration to detect vibration and shut of machinery before a catastrophic disaster.

The 365A malfunction detector provides maximum protection for large motors, pumps, compressors and the types of rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur. The 365A is UL, and c-UL certified Explosion Proof, type 4/4X and IP66 Weatherproof and ATEX certified (E365A).

Installed 365A Switch

The Model 365A and #365A Vibraswitches empty a magnetic circuit opposed by inertial and adjustable spring forces in the actuation mechanism. Operation of the Vibraswitches is as follows:
The armature is constrained so as to respond to only one direction of movement by frictionless flexure pivot compost of two overlapping blocks and a leaf spring leaded in one direction to hold the blocks together.  The armature totals on the pivot being forced in one direction by the adjusting spring force and the other direction by the magnetic force.
Then the entire assembly is subjected to vibration perpendicular to the base, the peak acceleration times the effective mass of the rmatureproduces an inertial force, aided be the adjustable spring tending to pull the armature away from the stop pin and the restraining force of the magnet.  When the peak acceleration exceeds the set point level the armature leaves the stop pin, increasing the gap and decreasing the force with the armature continuing to move up until it reaches the latch magnet, actuating the switch during its upward travel.
RESET is done by depressing the RESET button or applying power to the electrical reset coil.

Meltric DXN Explosion Proof Connectors

Meltric Hazardous Area DeContactors DXN from Sords Electric

DXN HAZARDOUS LOCATION RATED PLUGS & RECEPTACLES

MELTRIC DXN series plugs and receptacles are convenient, lightweight devices that are safe for the use in hazardous environments such as refineries or silos where exposure to flammable gas or dust is a concern.  The Meltric DXN’s compact size and durable construction makes them easy to handle and well suited for in-line connections of electrical equipment.  When used to connect modular equipment, Meltric DXN’s provide plug and play simplicity and help reduce costs by eliminating the need to expensive safety enclosures.  With Meltric DXN’s installed, users can safely connect or disconnect equipment under full load in potentially explosive areas. The Meltric DXN’s DEAD FRONT construction assures electrical safety by preventing user access to the live parts.  IP66+IP67 ratings are achieved as soon as the plug and receptacle are mated, making them the perfect choice for wet or dusty environments.

Live plugging and unplugging – How it works!

Arcing is a natural occurrence when electrical contacts make and break under load.  The purpose of a hazardous duty product is to prevent arcing from igniting hazardous gases or dusts present in the atmosphere into an explosion that may cause personal injury or damage to facilities and equipment.  The Meltric DXN d-contactor accomplishes this with specially designed flame-proof arc chambers.

The Meltric DeContactor arc chambers are sized to minimize the amount of atmospheric gas or air/dust mixture that may ignite during arcing and are built to contain this internal mini-explosion and withstand the pressure that is generates. The length and width of the flame-proof pathways are very precisely designed to provide for the effective dissipation of the pressure, while also ensuring that the arcing and internal ignitions of the gases or air/dust mixture in the arc chamber are totally isolated from the surrounding atmosphere.

When the Meltric Plug and Receptacle are connected, the flameproof arc chamber is completed with pressure relief/arc extinguishing pathways between the outer diameter of the plug contact and its associated contact hole in the safely shutter and between the main interior component and receptacle contact base.

Metlric DXN’s are current interrupting rated devices.  They can safely make or break under full load and also during moderate over-load situations.  During the making and breaking of contacts, the arc chamber completely contains any ignitions or gas or dust due to arcing and the flame-profo pathways dissipate the pressure.

As the plug is being removed or inserted, the flame-proof arc chamber and pathways re maintained.  This ensures continuous hazardous duty protection and the safety of the user.

When the Meltric Plug and receptacle are disconnected, the receptacle maintains a flame proof chamber.  In this case, the flame-proof pathway exists between the safety shutter and the main interior component.  The shutter also prevents access to live parts, providing users with the safety of a DEAD FRONT. The plug must be inserted into the safety shutter and be rotated in order to access the receptacle contacts.
