Pressure Switches

Conductivity level switchesTransmitters are based on the principle of measuring level through the electrical properties of the process material. As the name suggests, the conductivity based level switches and sensors sense the level of water or other conductive liquids that have free ions. These switchesTransmitters are successfully used in processing plants for conductive liquids , and serve the following applications: To avoid overflow For maintaining a constant level to avoid material wastage For switching off pumps when running dry and indicating an empty tank to avoid wear and tear and production stoppage

These Switches are the most versatile for level control and have advantages over float type switches in the control of agitated liquids paints-varnishes & heavy oil and foaming liquids. The Displacer weight is heavier than the liquid which is suspended by a spring. When the liquid rises the displacer looses the weight, this causes the spring to retract slightly to a new equilibrium position. This retracts of the spring interchanges the position of the Magnet provided at the top and actuates the switch. Upto three independent switch junctions are available in the single unit, with broad choice of operating sequences. These are flange mounted and are available with a choice of material of construction.

Level switch switch output potential free relay contact simple, low cost & reliable trouble free operation for conductive non conductive liquids protection class ip-65 level transmitter 2 wire system continuous 4-20ma dc output simple, low cost & reliable trouble free operation for conductive non conductive liquids protection class ip-65.

vibrating point level switch for high, low or demand levels of dry bulk solids in bins, silos or hoppers. This compact switch can be top, side or angle mounted. The vibrating fork design ensures the tines are kept clean, and the unique fork and crystal assembly design eliminates false high level readings even if tines become damaged. Used for liquidsolid interface detects settled solids within liquids or solids in confined spaces like feed pipes. It is designed to ignore liquids in order to detect the interface between a solid and a liquid. This has an optional 4-20 mA output for monitoring buildup on the fork in sticky applications, to determine the need for preventative maintenance. Key Specifications High resistance to mechanical forces, and strong vibration resistance to high bulk material loads Suitable for low density material: standard version, liquidsolid interface version, and low density option Low frequency, low energy operation High or low level alarm in solids with simple failsafe highlow selection
