Our Products
We offer the best product range of Honeywell Limit Switch, Vibration Fork Level Switch, Optical Level Switch, DANFOSS PRESSURE SWITCH and Zero Speed Switches.
vibration fork level switch (also called a tuning fork level switch) is a point level sensor used to detect the presence or absence of liquids, powders, or granular materials in tanks, silos, or pipelines.
Working principle
It operates on the vibration damping principle:
A fork-shaped probe vibrates at its natural resonance using a piezoelectric element
When the fork is in air it vibrates freely
When it is covered by material (liquid/solid) vibration is damped
This change in frequency/amplitude is detected and converted into an ON/OFF output signal
ZINACA Instruments +1
Essentially, it detects whether material is touching the fork or not.
Key features
No moving mechanical parts long life & low maintenance
Works with liquids, powders, and granules
Not affected by:
Density
Conductivity
Foam or bubbles
Temperature & pressure variations
VEGA +1
Fast response (1 second)
Can handle harsh environments (up to 150C, high pressure)
ZINACA Instruments
Applications
Storage tanks (high/low level alarms)
Silos (cement, grains, powders)
Chemical and pharmaceutical industries
Food & beverage processing
Water & wastewater treatment
Pump protection (dry-run prevention)
ZINACA Instruments
optical level switch is a type of point level sensor used to detect the presence or absence of liquid at a specific level in a tank or container.
An optical level switch uses infrared light:
It has an IR LED + phototransistor inside a small prism tip
When the tip is in air light reflects back to the receiver
When immersed in liquid light refracts (escapes) into the liquid
This change triggers an ON/OFF switching output
Process Sensing Technologies +1
it acts like a limit switch for liquid level detection.
Key features
No moving parts (solid-state low maintenance)
High reliability and fast response
Compact size
Works with many liquids (water, oil, fuel, chemicals)
Can handle high temperatures (up to 125135C in industrial models)
SMD Fluid Controls +1
Typical applications
Water tanks & reservoirs
Oil and fuel systems
Hydraulic systems
Chemical processing plants
Pump dry-run protection
Overflow / low-level alarms
zero speed switch (ZSS) is an industrial device used to monitor rotating equipment and detect when the speed becomes zero or falls below a set limit.
a Zero Speed Switch
A zero speed switch detects whether a shaft, motor, or conveyor is running or stopped.
Wikipedia
rotation stops (or slows too much):
The switch triggers a relay output
Applications
Conveyor belt monitoring (belt slip detection)
Industrial Monitor Direct
Crushers, mills, elevators
Pumps & fans
Gearboxes & rotating shafts
Safety interlocks before maintenance
It can stop the machine or give an alarm
