Optical Water Level Sensor Supplier for India
For buyers searching for optical water level sensor india, HojellyTek supplies factory-direct optical and photoelectric liquid level sensors from Shenzhen for Indian importers, panel builders, water-tech OEMs, and industrial integrators. We support export projects to India with bulk quotation, voltage/output matching, દસ્તાવેજીકરણ આધાર, and practical after-sales communication across China–India working hours.
Our sensors are used where float switches are too large, too slow, or too prone to jamming: ઓવરહેડ પાણીની ટાંકી, RO systems, ડોઝિંગ ટાંકીઓ, ઉપકરણ જળાશયો, compact water modules, કૂલન્ટ ટાંકીઓ, and OEM equipment that needs a clean point-level signal.
Factory Supply Capabilities for Indian Buyers
HojellyTek manufactures optical liquid level sensors using photoelectric sensing technology. A typical sensor uses an infrared LED, ફોટોટ્રાન્ઝિસ્ટર, અને પ્રિઝમ સેન્સિંગ ટીપ. જ્યારે પ્રિઝમ શુષ્ક હોય છે, light reflects internally and the receiver detects a strong signal. જ્યારે પ્રવાહી પ્રિઝમને આવરી લે છે, પ્રકાશ પાથ બદલાય છે, અને સર્કિટ આઉટપુટ સ્ટેટ સ્વિચ કરે છે. This allows fast point-level detection without a moving float.

India-Specific Buying Concerns: કિંમતો, Ports, Voltage and Documents
Indian buyers usually do not evaluate the sensor only by unit price. The real decision includes landed cost, import process, voltage compatibility, wiring support, દસ્તાવેજીકરણ, and long-term batch consistency.
For importers and distributors, the key issue is repeatable supply. You may need samples first, then a bulk order with consistent body material, કેબલ લંબાઈ, carton packing, લેબલીંગ, and document format. We can quote for batch supply and provide INR-friendly reference calculations, while the official commercial invoice is normally handled in the agreed export currency.
For panel builders, the biggest concern is electrical matching. A sensor that works on a test bench may still cause trouble if the NPN/PNP output, pull-up resistor, PLC ઈનપુટ, રીલે મોડ્યુલ, or controller logic is not confirmed. ઓર્ડર આપતા પહેલા, share your control board voltage, input type, વર્તમાન આવશ્યકતા લાવો, કેબલ લંબાઈ, and whether the signal should change on “liquid present” or “liquid absent.”
For water-tech OEMs, the priority is compact size, stable switching, and long-term compatibility with the liquid. RO plants, purifier tanks, ડિસ્પેન્સિંગ સિસ્ટમ્સ, and dosing equipment often need a small sensor body that can be mounted without taking too much tank space. If the liquid contains chemical additives, high mineral content, or cleaning agents, wetted material selection becomes more important than the sensor price.
For compliance, we can support common export documentation such as datasheets, વાયરિંગ આકૃતિઓ, test information, CE-related documents where applicable, and product material details. BIS requirements depend on the final product category and Indian regulations for that equipment. We do not claim BIS approval unless it is confirmed for the exact product and application. Indian buyers should verify BIS, duty, GST, and HS code treatment with their importer or customs broker before shipment.
Popular India Applications for Optical Water Level Sensors
Overhead Water Tanks and Overflow Protection
In many Indian buildings, વિલ્લા, ફેક્ટરીઓ, and apartment systems, overhead tanks need reliable high-level or low-level detection. A float switch can work, but it may be too bulky or affected by mechanical wear, થાપણો, or movement inside the tank. An optical sensor offers a compact electronic switching point.
For pump panels, the sensor can be used as part of an overflow alarm, dry-run protection logic, or high-level stop signal. The control design should include proper relay or controller input protection, especially where pump motors and long cables create electrical noise. For this use case, અમારું ઓવરફ્લો પ્રોટેક્શન સેન્સર page is a helpful reference.
RO Plants, Purifiers and Water-Tech OEM Equipment
RO systems often need compact sensing in clean-water tanks, storage modules, or dispensing reservoirs. Optical sensors are useful when the product design needs a small footprint, no mechanical float arm, and a fast digital signal.
For OEM buyers in India, important RFQ details include tank wall thickness, માઉન્ટ કરવાની દિશા, સપ્લાય વોલ્ટેજ, આઉટપુટ તર્ક, expected water quality, કેબલ રૂટીંગ, જોડનાર પ્રકાર, and whether the sensor is used for full, ખાલી, or overflow detection.
Industrial Dosing and Chemical Tanks
ડોઝિંગ સિસ્ટમ્સ માટે, textile auxiliaries, cooling circuits, and industrial liquid handling, material choice matters. PSU plastic may suit many water applications, while PTFE, 316 સ્ટેઈનલેસ સ્ટીલ, or glass may be considered for more demanding liquids. Do not choose the body material only by cost. Check chemical compatibility, સફાઈ પ્રક્રિયા, તાપમાન વિસ્તાર, tank pressure condition, and whether foam, પરપોટા, આવરણ, or residue may affect the prism surface.

Can the sensor work with 5V, 12V, or 24V control systems?
Voltage must be confirmed by model and project. We can review your control board or panel input and recommend a suitable supply voltage and output type before sample approval.
મારે કયું આઉટપુટ પસંદ કરવું જોઈએ: NPN, PNP, અથવા 4-20 એમએ?
NPN and PNP are common for point-level switching. 4–20 mA is more relevant when an analog or continuous level signal is required. Share your PLC, નિયંત્રક, or PCB input so the correct output can be selected.
What documents are available for importing into India?
Typical export support may include datasheet, commercial invoice, packing list, વાયરિંગ આકૃતિ, and relevant test or compliance documents where applicable. BIS applicability should be checked based on the final product category and current Indian regulations.
Which material is best for RO water, રસાયણો, અથવા તેલ?
For clean water and RO applications, suitable plastic options may be enough. આક્રમક રસાયણો માટે, તેલ, or industrial dosing, PTFE, 316 સ્ટેઈનલેસ સ્ટીલ, or glass may be considered. Final selection depends on liquid composition and operating conditions.
Can the sensor be customized for Indian OEM equipment?
હા. OEM/ODM options can include cable length, કનેક્ટર, વાયર ક્રમ, માઉન્ટ કરવાની શૈલી, આઉટપુટ તર્ક, બોડી મટિરિયલ, લેબલીંગ, and packing. Sample testing is recommended before bulk production.
