Performance Features

Performance characteristics:

PD-750QC The crystalline silicon pressure sensor technology and the patented packaging process are carefully crafted into a robust and sanitary pressure transmitter. Adhering to the design concept of fully satisfying harsh use occasions, the PD750Q monocrystalline silicon sanitary pressure transmitter adopts a fully isolated and sealed structure to eliminate the influence of humidity and is suitable for harsh wet cleaning occasions; the double diaphragm overload protection structure can withstand a pressure of 42MPa, It is suitable for severe pressure overload occasions; the transient voltage resistance meets the four-level standard (differential mode voltage: 2000V, common mode voltage: 4000V), suitable for harsh surge voltage occasions; 20 linear points in seven temperature zones, 160 pressures Calibration point, suitable for severe temperature changes.

Product advantage:

■ Single crystal silicon pressure sensor, double diaphragm overload protection structure, calmly cope with high overload test.

■ Special integrated circuit and signal transmission module of surface packaging technology, the key parameter operation function is friendly, and the measurement data can be displayed quickly.

■ ISO228, DIN3256 and other complete global standard or industry standard process connections, exquisite stainless steel welding technology and surface treatment technology, in line with hygienic standards.

■ Rugged one-piece stainless steel housing ensures long life.

■ Stainless steel surface roughness Ra≤0.4μm, in line with sterile standards.

■ Warranty: Up to 3 years valid warranty

Field of application:

■ PD-750QC Sanitary Differential Pressure Transducer The transmitter is widely used in food, brewing, pharmaceutical and other industrial fields to realize the measurement of liquid, gas and steam pressure.
