When you require dependable weight estimation in requesting situations, our ceramic capacitive pressure sensor QS-P105F conveys extraordinary execution. This cutting-edge sensor combines the toughness of 96% Al2O3 ceramic fabric with progressed capacitive innovation. You'll get exact estimations from -1 to 600 bar with exceptional exactness. The sensor highlights great resistance to erosion and scraped area, making it idealize for cruel mechanical conditions where conventional sensors fail.
Qintai sensor employments a ceramic stomach that reacts to connected weight. When weight changes happen, the stomach distorts marginally. This distortion changes the capacitance between the stomach and a settled anode. The framework at that point changes over this capacitance alter into an electrical flag that precisely speaks to the weight you're measuring.
This innovation offers you a few preferences over conventional detecting strategies. You get higher precision, superior long-term soundness, and predominant resistance to natural factors.

The 96% Al2O3 ceramic development gives extraordinary resistance to cruel chemicals, extraordinary temperatures, and mechanical push. You can depend on steady execution indeed in the most challenging applications.
Your applications advantage from our sensor's amazing temperature run of -40°C to 135°C. The weight extend ranges from -1 bar to 600 bar, covering most mechanical requirements.
With non-linearity of fair 0.3% FS and comprehensive precision of ≤±0.5% FS, you get the accuracy your basic applications demand.
The 2-30VDC supply voltage run makes integration into your existing frameworks clear. The compact plan permits establishment in space-constrained situations.
