  MDI Mercury Contactors  

Mercury Displacement Relays are all designed and built to meet the most exacting demands of industry. Contactors are hermetically sealed with high quality glass to metal seals. The stainless steel tube is totally encapsulated in high grade UL approved epoxy to prevent moisture damage and voltage breakdown through the protective coating. Inert gases internally prevent excessive arcing between the mercury and the electrodes which enables the unit to function for millions of cycles. Available in 30, 35, 60 and 100 amp capacity.

Derate Chart for Heat Sinking SSR

         
  GN Heat Seal Strips  

Particular attention must be paid to thermal considerations in order to improve the reliability and power of solid state relays. It is extremely important to consider the quality of the interface between the relay and the heat sink. Air pockets or gaps risk causing hot spots and a significant rise in temperature. This pad is made of an aluminum substrate covered on each side with a "touch-dry" thermal compound. If the temperature exceeds 51°C, the thermal compound wetting action allows it to fill any gaps, while its natural capillary action draws it to the edge of the interface between the mating surfaces, thus preventing it spreading.

Liquid Level Controls back to top
  LLC Liquid Level Control  

Model LLC control is designed to de-energize the power supply to a heater if the liquid level of the solution should drop below the heated portion of the heater. The two setting probes of the control are immersed in the solution to be heated. A negligible current flows between the probes when immersed. Once the liquid level drops below the probe, the circuit is automatically de-energized. The probes are available in stainless steel, titanium, or impervious graphite for use in almost any solution.

  ENR Level Up or Level Down Control  

Control of maximum and/or minimum levels of conductive liquids such as water. The principle is based on measurement of the apparent resistance of the liquid between two submerged probes. When this value is lower than the preset threshold on the unit front face, the output relay changes state. To avoid electrolytic phenomena, an AC current fans across the probes. Applications found in environmental, chemical industries and food technology etc. DIN rail mount.

The output relay changes state when the level of liquid reaches the maximum electrode, with the minimum electrode submerged. It returns to its initial state when the minimum probe is no longer in contact with the liquid. 24 to 240 VAC.
