Feature: 1. Transmitter is assembled with imported silicon differential pressure and pressure sensitive chip, aluminum alloy shell and stress isolation technology. 2. With high measurement accuracy, air transmitter is suitable for all kinds of non-corrosive, air pressure or differential pressure measurement. 3. After precision temperature compensation and circuit amplification technology processing, air pressure sensor is converted into 4-20M standard signal output and interfaced with industrial computers or distributed systems. 4. Such transmitter has a compact structure, sturdy and light weight, and is easy to install. The 0 range can be continuously adjusted externally and the migration range is wide. 5. And this air tester can be widely used in the measurement of air duct pressure or differential pressure in hospital ward ventilation, petroleum, chemical, metallurgy, power plants, etc. Specification: Item Type: Air transmitter Model: LCD air pressure Type: Micro differential pressure transmitter Measuring Medium: Wind Display: LCD Power Supply Voltage: DC24 (V) Output Signal: 4-20 (mA) Measuring Pressure Range: 0-100Pa / 0-200Pa / 0-300Pa / 0-400Pa / 0-500Pa / 0-1kPa / 0-1.5kPa / 0-2kPa / 0-3kPa / 0-4kPa / 0-5kPa / 0 -10kPa / 0-20kPa / 0-30kPa / ± 100Pa / ± 200Pa / ± 300Pa / ± 500Pa (optional) Compensation Temperature: -10 ~ 70 ℃ Working Temperature: -20 ~ 85 ℃ Comprehensive Accuracy: 0.5% Measuring Medium: Non-corrosive dry air Pressure Measurement Form: Differential pressure (applicable to negative pressure in furnace pipes) Pagoda-Shape Connector Interface Diameter: φ8mm x 2 Pagoda-Shape Connector Interface Thread: M10mm x 2 Installation Aperture: φ4mm x 2.
