Electronic Switches

Product Details:

Switzer rotary vane level switches are one more addition to the vast range of level switches and is best suited for bulk materials. Rotating vane driven by a most reliable synchronous motor ensures a very smooth continuous rotation until it is stopped by an approaching level of solids to the desired value. When the level of the solid raises and obstructs the vane, rotation of vane stops and a change-over occurs in the instrument quality snapacting microswitch. The motor also stops rotation and starts again when the level recedes and vane is free to rotate.

Level Switch Model K–5720 is exclusively designed to monitor level of conductive & non-conductive liquids, such as chemicals, lubricating oil, compressor seal oil, water.The level is sensed by a PTC thermistor, which isto be fixed in the vessel or lube oil tank or sump at a location where the presence or absence of the medium in terms of level is to be monitored.When the tank is filled up, the level sensor is in contact with the liquid, and exhibits a low resistance, so the relay is in ‘OFF’ condition.When the liquid level goes down, the sensor is exposed to air and exhibits high resistance, switching the relay ‘ON’.When the liquid level is restored back to the required normal level and encompasses the sensor, its resistance once again reduces. The relay returns to the normal status automatically. An optional manual reset facility can be provided to restore the relay to its normal status. This feature ensures that the operating personnel confirm the availabilityof the liquid, while running an equipment.Status indicating LEDs are provided for Power ‘ON’ condition Red and Relay ‘ON’, absence of medium,Yellow.A 2 core cable of 2 metres length is provided withsensor as standard. Longer cable upto a maximum of 5 metres can also be provided if required by user.

We have achieved a distinct and dynamic position in the industry by providing a wide assortment of Pressure Switch Prince 901. The switching frequency provides information about the possible number of switching cycles per minute.  The figure given of 200/minute is intended only as a guideline.  Depending on the type of switch and the operating conditions a considerably higher number of cycles can be achieved. Known for their easy installation and flawless finish, these are widely demanded in the industry.


Features:

• Abrasive and chemical resistant
• Intrinsically safe version (LCIE 03 ATEX 6300 X)
• Two threshold outputs (PNP transistors or galvanic isolation)

With the help of skillful and devoted professionals, we are engaged in offering the best quality range of Pressure Switch Bourdon 931 to the customers. This pressure switch is used for sensing fluid pressure contains a capsule, bellows, Bourdon tube, diaphragm or piston element that deforms or displaces proportionally to the applied pressure. The resulting motion is applied, either directly or through amplifying levels, to a set of switch contacts. Moreover, the whole range of products is checked on well define industry parameters prior to its dispatch.


Features:

• Good resistance to vibration and overpressure
• Measuring range: 0...1 to 0...100 bar
• Overpressure / Static pressure: max. 200 bar

Additional Information:

• Item Code: Bourdon-931

Switzer model 711 electronic pressure switch is a versatile electronic instrument matching with contemporary designs with all the fundamentally required features for basic control functions.
the instrument is provided with lcd indication, two
independent set point on-off control relay outputs and analog output of 4 to 20ma. Operational settings are done through 3 keys on the front membrane keypad.

We are profoundly offering a comprehensive array of Pressure Switch Sovereign Prince. By using a micro-switch with changeover function, the normally open and normally closed operation can be combined into a single pressure switch.  The plunger operates a swivel contact.  In the pressurized state the circuit is closed by the normally closed contact.  If the pressure applied exceeds the adjusted set point then the swivel contact changes enclose the circuit using the normally open contact.


Features:

• Pressure Range: 1....3 / 6 / 10 / 16 / 13 Bar
• Repeatability: 2.0 %
• Switch Rating: 15 A, 220 VAC & 10 A, 24 VDC

Taking ongoing market into consideration, we are presenting a large collection of Pressure Switch Series 200. If the force resulting from this pressure is greater than the force exerted by the pre-loaded switch point set spring then the plunger moves taking with it the contact disc, which closes the circuit between the contacts. When the pressure falls again by an amount greater than the hysteresis the switch opens again. By turning the set screw the pressure switch can be adjusted within its pressure switching range.


Features:

• Repeatability : 1.0 %
• Switching Rating: 15 A, 220 VAC & 0.4 A, 110 VDC
• By using a micro-switch with changeover function, the normally open and
