Характеристики

Product Description:

PY301 Air Pressure & Differential Pressure Transmitter adopts high-precision, high stability diaphragm and is assembled by stress isolation technics. By strict precision temperature compensation and signal amplification, transfer micro differential pressure, air pressure, flow and other parameters to reliable 4~20mA or 1~5VDC, 0~5VDC, 0~10VDC signal output.

Product Features:

A. Imported silicon differential pressure sensing chip;
B. Advanced lamination technology with zero and full range compensation and temperature
compensation;
C. High precision and high stability amplifier integrated circuit has the functions of moisture-proof,
anti-condensation, anti-leakage and anti-lightning;
D. Diversified output signals (4-20ma, 0-5v, 0-10v).

Product Application:

A. Air duct pressure measurement;
B. Fan pressure measurement;
C. Measurement of subway air pressure;
D. Environmental wind pressure measurement of meteorological department;
E. Pressure measurement such as boiler air supply, underground ventilation and indoor air pumping.
