Quality characterizes everything we do at Qintai. Qintai ISO9001 and IATF16949 certifications guarantee each transducer meets exacting fabricating measures. With 58 innovation licenses and ceaseless R&D speculation, we remain at the cutting edge of weight detecting innovation.
The QS-P218 highlights stainless steel development utilizing premium 17-4PH or 316L materials. These materials stand up to erosion whereas keeping up basic astuteness beneath extraordinary weights. Your transducer will perform reliably for a long time, indeed in forceful chemical environments.
Temperature recompense from -10°C to +80°C guarantees precise readings over changing conditions. The thin film pressure transducer keeps up ±0.02% FS/°C temperature float, giving steady estimations when warm conditions fluctuate.
Flexibility sets our weight transducers separated from standard offerings. Select from different yield setups counting analog signals (4-20 mA, 0-5V, 0-10V) or computerized communication (RS485, CAN). This flexibility disentangles integration into existing control systems.
Process associations oblige universal measures counting G1/4", G1/2", M20×1.5, and NPT1/4". Custom associations are accessible to coordinate your particular mounting prerequisites. Electrical associations incorporate Clamor 43650, M12×1, cable outlets, or specialized car connectors.
For extraordinary temperature applications, high-temperature models work up to 200°C. Explosion-proof plans (Ex ia IIC T6 Ga) meet dangerous region prerequisites. Smaller than expected adaptations fit compact water powered frameworks where space is critical.
Industrial mechanization frameworks advantage from the QS-P218's quick 1 ms reaction time and remarkable repeatability. Handle control applications depend on the transducer's long-term steadiness of ≤0.2% FS/year for reliable performance.
Automotive applications use our position as the number one OEM provider in China, serving major producers like Weichai Control, Yuchai Control, and Quanchai Control. The transducer's vibration resistance (20g) and stun resistance (100g) handle car situations easily.
Hydraulic frameworks working at tall weights advantage from the transducer's amazing burst weight rating of ≥300% full scale. This security edge secures your hardware and work force amid weight spikes.
