HM29 digitization? It is the digitized intellectual products of a kind of high precision which Germany HELM developed to the market demand in China’s Mainland that the intellectual pressure / difference presses the changer, this series of products adopt Germany HELM most high-performance sensor chip, combine the single-chip computer technology and digital switch technology of sensor and is designed in meticulously. The key part adopts 24 MCU microprocessors of AD, its strong function and high-speed operation ability have guaranteed the fine quality of the changer. The whole design frame focuses on dependability, stability, high-accuracy and intelligent, meet the requirement that industry improved day by day employs live. The software kit of the products has a strong function too at the same time, do not need hand holding device, have guaranteed the good interaction. The treatment technology of the signal of Applied Digital, make it have fine ability to resist interference. And possess the automatic stability traceability (ZSC) of the zero point Compensate ability (TSC) with the temperature automatically .
HM91 miniature pressure sensor and the changer, for the requirement for is examined in the field and flow, lays the position or trends loudly frequentlying, must examine it while pressing in situ, often have a comparatively harsh requirement on microminiaturization of the external dimension of the sensor, and in cases a state flows in the interference that not, the change law of the field of pulsing and flowing of reproducing. HM91 miniature, ultrathin pressure sensor and changer just demand to design for the above-mentioned operating modes, this series of products have adopted silicon a pile of silicon technology of sensor of Germany HELM pressure, high precision integrates and pigeonholes the quick component of resistance, utilizes internationally advanced microminiaturization to make and encapsulate the craft, carry on exquisite and ingenious miniature encapsulation, make it small, compact, light, sturdy and duable, and have fine dynamic and inactive state characteristics.
Use of the products
