When you require solid fluid level estimation in mechanical applications, choosing the right Level transmitter makes all the contrast. Our QS-P400 arrangement offers remarkable exactness and toughness for water, oil, diesel, urea, and different chemical fluids. Built with progressed piezoresistive ceramic innovation, these sensors provide reliable execution over requesting situations. Whether you're observing tank levels, controlling forms, or guaranteeing security compliance, our arrangements give the unwavering quality you can believe for basic operations.

Qintai fluid level sensors utilize demonstrated piezoresistive ceramic innovation. This approach conveys remarkable affectability and linearity over wide weight ranges. You get exact estimations from 0.5 meters up to 500 meters of water column.
The ceramic stomach development stands up to erosion and chemical presentation. This implies longer benefit life in unforgiving situations. Your upkeep costs remain moo whereas estimation unwavering quality remains high.
Installation couldn't be less demanding with our immersion-type plan. Basically lower the sensor into your tank or vessel. The weighted cable guarantees appropriate situating each time.
Multiple mounting arrangements suit diverse applications. Select from strung associations, flanged mounting, or coordinate submersible establishment. Cable lengths are customizable to coordinate your particular requirements.
Precision things in level estimation applications. Qintai Level transmitter conveys precision inside ±0.25% of full scale. This uncommon performance ensures your processes stay within tight control parameters.
Temperature emolument keeps up exactness over working ranges from -40°C to +85°C. Your estimations remain dependable in any case of regular varieties or handle temperature changes.
