A3000 Photohelic Pressure Switch

Photohelic® SwitchGages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Photohelic® switchgage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. Two phototransistor actuated, DPDT relays are included for lowhigh limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25" (0-6 mm) w.c. up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar). Photohelic Sensing - How It Works In typical applications, these Dwyer switchgages control between high and low pressure set points. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation. Relay-Transformer Features A plastic housing protects all electronic components. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards.

SIGMA's Flow Switch is an extension of the level switches. There are two types of flow switches : one for low flow / line size up to 50 mm line size (Model FS 1000) and another from 25 mm onwards up to 800 mm or above (Model FS 1010).Operating Principle :Model FS 1000 is a valve type Flow Switch wherein an increase in flow through the body raises the valve disc depending upon the flow. This in turn raises the magnetic sleeve moving inside a non-magnetic enclosure. The movement of the sleeve attracts the magnet located outside the tube which in turn actuates a micro switch. Decrease in flow reverses the action.Model FS 1010 is a target type which moves from a vertical position to a near horizontal position as the flow increases. This change in position moves a magnetic sleeve in a non-magnetic enclosure. The movement of the magnetic sleeve attracts a magnet which in turn actuates a micro switch. Decrease in flow brings the target back to the vertical position.
