VIBRATING FORK LEVEL SWITCHE work on vibration damping principal and are used for material with low densities where rotary paddle switches can not be used. The vibrations also provide self cleaning action, so these level switches can easily be used for materials that stick to probe and tank wall. The electronically stimulated fork vibrates at it’s mechanically resonance frequency of 125 Hz when the fork is free of the service material. The resonance is caused by the piezoelectric crystals. One of the Piezo crystals produces a small voltage which is transmitted to the switching amplifier. If the fork is covered by the bulk material, a damping effect is produced and the Piezo crystal does not produce the voltage and the amplifier will be switched on and a corresponding signal output is actuated. Small depositions on the container wall do not affect the operation of our switch. The switches are supplied with integral electronics and are available in lengths from 250 to 3000 mm. The Vibrating Fork Level Switches are extensively used in building, cement, food dairy, plastic, timber, chemical and mining industries. The operating temperature for standard model is 150 Deg C and can be custom made to suit temperature up to 200 DegC. These switches are supplied with heavy duty SS316 forks and can be successfully used for most applications like - bins and hoppers requiring minimum and maximum level detection of solids, powders, granules, pellets, flakes, etc. These are not affected by incoming material. They are highly sensitive, reliable, easy to install, require no calibration, economical and suitable for highly dusty environment. The vibrating fork level switches are extensively used in building, cement, food, dairy, plastic, timber, chemical and mining industries.   Vibrating Fork Level Switch Manufacturer, Exporter and Supplier Vibrating Fork Level Switch is the Main Product of VEKSLER INSTRUMENTS.

SIDE MOUNTED MAGNETIC LEVEL SWITCH manufacturer, exporter and supplier SIDE MOUNTED MAGNETIC LEVEL SWITCH is an economical, maintenance free and a very reliable device used for high, low or intermediate point level switching. It is ideal for tanks with inaccessible tops or bottoms and where insertion depths of top mounted models are exceeded. The construction is compact & rugged with a free moving pivoted float assembly. The Switch assembly is mounted in a non-magnetic material to achieve undisturbed magnetic flux. It employs dual magnets, one linked with the float arm and other by the contract carriers housed in the switch enclosure. Change in the liquid level brings the like poles of dual magnets opposite to each other & resulting repulsion force ensures a changeover of contacts with snap action. The magnetic transmission is glandless so there is no scope of leakage from vessel into switch housing. These switches are manufactured in various materials and enclosures to suit broad range of media/applications. They are designed to provide high repeatability and to minimize effects of shock, vibration & pressure.

  The sensor element consists of a Bimetal combination having different thermal expansion coefficient. This difference in their thermal expansion coefficient produces a mechanical motion. The sensing element of the Controller is installed directly in the process vessel. The temperature changes inside the process will result in the following Incase of a rise in temperature, the inner metal rod will expand and will contract incase of a decrease in temperature. The change in length is proportional to the change in temperature. The outer metal tube has a low expansion coefficient and thus change in length is negligible. But since one end is attached to the inner metal tube, the inner rod moves as the outer tube changes length. The opposite end of inner rod pushes against a floating link. It is held concentric with a spring loaded inner valve. When the temperature decreases, the inner rod applies pressure on the floating link, it causes pivot to move around the adjustment fulcrum point which tilts the inner valve plug thus the output signal increases. The temperature can be adjusted by moving the knob on the fulcrum.   PNEUMATIC TEMPERATURE CONTROLLERS Introduction   The instrument is provided with two adjustments (a) temperature set Point control and (b) Proportionality control. The temperature can be adjusted and where between - 50° F to + 750° F. The proportionality control is given to set the desirable temperature span. The proportionality control, calibrated from 5 to 60° F corresponds to produce 0.2 - 1 Kg / cm2 output.The orifice in the seat is eccentrically drilled so that while rotating the seat it moves the rifice with respect to the adjusting serew. This regulates the orifice opening with respect to temperature changes.

Temperature Range : -50 to 750 Deg F

 [ Pneumatic Level Controllers (Model: PLC-19) ] PNEUMATIC LEVEL CONTROLLER (Pneumatic Controller) works on the buoyancy principle. The force applied is propotional to the volume of liquid displaced. Change in the liquid level produces a change in the position of flex tube end. This causes movement of the flex tube shaft to which carrier assembly is connected. Carrier assembly opens or closes the nozzle to give pneumatic output from the pilot valve.   PNEUMATIC CONTROLLER Introduction Pneumatic Level Controller consists of a displacer mounted to the flex tube. The Pilot Valve and carrier assembly are housed in weather proof IP65 housing. The exhaust gas is vented inside the enclosure and then to the atmosphere through a vent hole. The instrument is known for its simplicity, reliability and ease of maintenance. Reverse action can be obtained Nozzle assembly by 180°.     Connection 4" NB CS, ASTMA 105 Flange as standard in 150 # , 300 # , 600 # Enclosure Die Cast Alluminium, weather proof to IP 65 Flex Tube Material SS 304 / SS 316 / SS 410 Displacer Options Vertical (S.Steel) 75mm x 355 mm Long (+ 2mm)   Vertical (S.Steel) 42mm x 200 mm Long (+ 2mm)   Vertical (Phenolic) 90mm x 115 mm Long (+ 2mm)   Horizontal (S.Steel) 75mm x 152mm Long (+2mm) Differential 10 to 30 mm depending on size of displacerr & S.G.

We are experienced Level Switch manufacturer in India. We preffered as Level Switch Manufacturer in India. In PADDLE TYPE LEVEL SWITCHES, a small electric motor drives the paddle, which rotates freely in the absence of material. When it is impeded by material the motor will be turned within the housing thus loading a spring and triggering two switches. One of them is a dry electric contact of control and alarm functions while the other is to cut off the power of motor. When the material level drops, the loaded stretched tension spring returns the motor to its original position and the unit is reactivated.Our Rotary Paddle Switches are heavy duty and suitable for level detection of dust granules and free flowing solids upto the size of 10 mm. These can be mounted in bins, hoppers and silos and are useful to control level, filling and emptying. Applications areas include Agriculture industries, chemical industries, Food industries etc.     Paddle Switch, Level Switch and Paddle Type Level Switch manufacturer, exporter & Supplier India We are wellknown Level Switch manufacturer in India. Paddle Switch, Level Switch and Paddle Type Level Switch are main product of our company Veksler Instruments which manufactures, exports and supply Industrial Measuring Instrument.

Micro Valve Level Controllers (Model:MVLC-19)   MICRO VALVE LEVEL CONTROLLERS This is a snap-acting float operated level controller with a 3 way MICRO VALVE. When the level rises and raises the float, it is actuated by two adjustable york-type pusher arms. The pusher arms can be adjusted to accurately control the range of level desired.The valve is in low level position when the liquid level is below the float and it remains the same until the float rises to the pre-set high level. The Micro Valve then reverses the positions until the float drops to the pre-set low level position. instrument is supplied with Flange & Grooved Coupling for mounting on to the vessel. it is mounted from side of the tank.Standard instruments are supplied with a three way Micro Valve and three ¼" NPT ports and the working pressure is 2 Kg/cm2. Connections to the ports also depend on the control action desired.
