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 transmitterModel: LCD air pressureType: Micro differential pressure transmitterMeasuring Medium: WindDisplay: LCDOutput Signal: 4-20 (mA)Compensation Temperature: -10 ~ 70 Working Temperature: -20 ~ 85 Comprehensive Accuracy: 0.5%Measuring Medium: Non-corrosive dry airPressure Measurement Form: Differential pressure (applicable to negative pressure in furnace pipes)Pagoda-Shape Connector Interface Diameter: 8mm x 2Pagoda-Shape Connector Interface Thread: M10mm x 2Installation Aperture: 4mm x 2.Package List:1 x Air Transmitter Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
