Features: The transmitter has high sensitivity, high accuracy and strong overload resistance. Highly integrated sensor and amplifier circuits; Die-cast aluminum alloy is adopted, zero point and accuracy of circuit board need not be adjusted; Strong anti-interference ability, long-term stability and reliability. Adopts unique stress isolation technology, and after precise temperature compensation and high stability amplification processing, the signal of the measured medium will be converted into 4~20mA output signal. Applicable environment: widely used in medical treatment, clean room, boiler, dust collector, vacuum cleaner, power plant, air conditioning and other environment pressure measurement. Measuring medium: non-corrosive gas. Specification: Range: -2kpa ~+2Kpa, -1kpa ~+1Kpa, 0-500pa, 0-1kpa, 0-3kpa, 0-4kpa (optional) Overload capacity: single end minimum pressure 4Kpa, maximum pressure can not exceed 25 times the range Measurement accuracy: 0.2%FS Output signal: 4~20mA Power supply: DC24V Temperature drift:±0.1% FS /℃ Ambient temperature: - 30℃~ + 80℃ Ambient humidity:≤85%RH Weight: 215 g / 7.6 oz(approx.)
