SMARTsaa is lesding manufacturer and exporter of range of Rectangular Block TYpe Inductive Proximity Switches with extended sensing range.
These proximity switches are used where higher sensing range is required.
These switches also find application on large equipments where the critical alignment is no possible.
Typical application includes:
1.Bucket Elevator : To sense misalignment of buckets
2.To sense movement of stacker on rail to communicate stacker location to control room
3.To  detect object on heavy machines  where vibrations are more
4.Detect movement of wheel of equipment moving on rail

Product Details:

SMARTsaa is leading manufacturer and exporter of Capacitance Proximity Switches used for sensing level of liquid and powder. The sensor is designed to sense level of oil in a tank, powder in hopper or bins by non-contact way.

OPERATING PRINCIPLE OF CAPACITIVE PROXIMITY SWITCH

The sensor works on the principle of change in dielectric constant of different media. The change in capacitance in empty state and filled state is detected by sensor and output signal is produced.

The Capacitance Proximity Switch is to be fitted in a tank or hopper at a point where level is to be sensed.

Various sizes of switches are available. M 18 & M 30 sensors are most common. These switches works on 24 V DC and offers PNP or NPN O/P.

Sending range of Switch depend on diameter of sensor and dielectric constant of object to be sensed. We offer sensitivity adjustment trimpot at the backside of the sensor to fine tune the sensor as per site condition on machine.

SMARTsaa Capacitive Proximity Switch can also sense level of oil from outside the tank if it is made up of plastic.

We offer Switches equitant to Omron capacitive proximity switch / Allen Bradley Capacitive Proximity Switch/ Pepperl & Fuchs Capacitive Proximity Switches.

SMARTsaa Capacitive Proximity Switch Price is affordable and economical

Working Principle of Tubular Zero Speed switch :
The sensor (Inductive Type) and control unit are housed in sensor housing. Sensor is placed in close proximity of the rotating object. On this object, metallic plates are fixed. Sensor detects presence of metal objects which come within the range of their oscillating field giving rise to corresponding pulses. These pulses are fed to the control unit where they are compared with the standard pulses to sense the speed

In case of under speed – zero speed application built-in initial by-pass time delay is provided to allow the rotating machinery to attend the desired speed. If after this set time the motor does not attend the set speed, the load relay is de-energized and the switch resets automatically when the desired speed is attained.
