Proximity Switch is a critical element of Sensing, Automation and Control. Based on the ' Object of Sensing' principle, these switches are available in Inductive, Capacitive, Optical, Ultrasonic and Magnetic types.
It senses only metallic objects; Useful for medium counting speed; Short sensing gaps. These switches are available from 4 mm diameter (M4) to 140 mm diameter (M140) with sensing distance from 0.5 mm to 100 mm. These switches are most reliable option for applications in Machine tools, Foundries, Rolling mills, Automobile, Textile, Pharmaceutical, and Material Handling Systems.
It senses non-metallic, metallic objects as well as liquid; Low counting speed. These are offered in tubular threaded housing from size M12 to M80. Has rugged construction along with IP-68 grade of protection; Very useful for liquid level monitoring applications.
It senses any object;Longer Sensing Distance; Medium counting speed; High position sensing accuracy. These are Infra-red type sensors incorporating advance and reliable technology. These are offered in tubular metallic, acrylic & plastic enclosures. Special models of Optical Switches are available with an integrated Optical Fibre cable for flexible mounting and for sensing miniature objects / high temperature objects.
These switches are ideally suitable for level monitoring applications. The sensing range can be from 0.2 m to 20 meters. These sensors have the ability to perform in dry and dusty environments. These sensors are immune to electrical noise levels generally present in the typical industrial environment. The ultrasonic sensors find applications for Anti-collision detection for cranes, Level controller for liquids and solids, Detection of moving object, Opening / Closing of doors by detecting motion.
It senses only ferrous objects/ magnets; High counting speed. These are available in M12, M18, M30 and above. Sensing range : 10 to 50 mm. Grade of protection is IP-68.These switches are used only for position sensing applications. These can also be used for Roto-meters, Direction sensing, Level Sensing of liquids.

Different types of Jayashree Level Sensing products are available for sensing levels of various material stacked in bunkers, open space, distance. etc..
Tilt switch level sensor is a very rugged and proven instrument for monitoring top level of bulk material stored in an open space or in a bunker / silo. It has a special level detecting probe which is beyond a preset angle due to piling of material. The sensor probe is available in a robust MS tube for solids and a light duty plastic tube for food grains and fertilizer. Special models for use in hazardous environment are available.
Jayashree Diaphragm Type Bin Monitor offers economical, reliable and durable point level controls for point level detection of dry bulk materials. The units can be used to eliminate bin overflow, maintain a pre-determined material level, indicate plugging of chutes or conveyors or provide any of a number of level control function. The flush mount, non-intrusive units are ideally suited when vessel size or internal clearance is limited or where protrusion into a vessel is not acceptable. All installation and servicing, including diaphragm replacement and sensitivity adjustment can be done from outside the vessel.
Jayashree RF capacitance sensors offer cost-effective, reliable point level monitoring and provide with the most affordable solution for your applications. These RF capacitance probes are designed to provide a high level of sensitivity, stability and durability for powder and bulk solids applications, as well as liquid and slurry applications and is backed by two years warranty
The RF Point Level Sensor is a most rugged and proven sensor for monitoring level in a chute. This is very useful for monitoring chute blockage. It is a special heavy duty disk / flange mounted probe. The probe senses only the steady level of coal lumps and does not actuate due to falling material dust or humidity. The effect of cable capacitance and drift with temperature is eliminated by using a driven shield arrangement. The controller unit operates an output relay when the coal level reaches near the sensor face. The probes are available for working temp. up to 200°C. Probes of different types are available for specific application like telescopic, Teflon coated etc..
The Ultrasonic level sensors of the Series SW 3051 are very useful for sensing high levels (up to 20 meters.) of liquids or slurry material. The sensor gives a 4-20 mA output signal to the controller and operates relays at preset high and low levels. Probes are available forsensing water levels of 5/10/15/20 meters.
Harmonics free Series Reactor (HFSR), the name derived from the electrical Standards and technology, The customised solutions offered by Jayashree brought a revolution in the motor starting concept, till date the concept stands as unmatched technology for its performance and reliability, Continuous up-gradation has improved the product with all modern requirements of system integration, data logging, control, automation, remote operation, the product is now branded and promoted with trade mark of HFSR™/FCMA™/SMSC/Rotastat/Rotacon by Jayashree.
Jayashree introduced the air core technology for soft starters in 1980’s , the first of its kind solution and invention offered for the commercial use, Air core superseded the dated magnetic core technology by its superior characteristics and performance HFSR™ ( air core and advanced magnetic core ) / FCMA™ ( auto-transformer based ) technologies are introduced and pioneered by Jayashree and promoted since 1987 , both trade mark registered by JEPL, offered solutions are as per customer requirements and suitable for the application.
