Specification More details: https://www.fandesensor.com/?page_id=910 Voltage: DC 24V Output signal: 4~20mA Range: -100KPa~0~100KPa Temperature compensation: 0 ~ 85 ¡É Ambient temperature: -20~85¡É Working method: Differential pressure Comprehensive accuracy: 0.5 Zero temperature drift: +0.03%FS/¡ÆC Sensitivity temperature: +0.03%FS/¡ÆC Overload pressure: 300%FS
Wind pressure transmitter selection and customization-- Measuring range: -100KPa~0~100KPa (intermediate range optional) Output signal: factory default 4-20mA Pagoda mouth size: the factory default is connected to 8mm air nozzle or 6mm/4mm is optional Features 1. Aluminum alloy shell: The product material is made of aluminum plate processing, all-aluminum alloy structure, high reliability, and elegant appearance. 2. Imported chip: The core adopts imported ceramic core, which has high precision, sensitive response and strong stability. 3.Pagoda mouth interface: Pressure measurement --- only need to connect to the H end interface Differential pressure measurement --- H end is connected to high voltage, L end is connected to low voltage Measure negative pressure --- only need to connect to the L end Application Indoor and outdoor pressure difference monitoring: By connecting the sensor and the control instrument, when the control instrument detects that the indoor and outdoor pressure difference reaches the preset upper limit value, the fan is started to reduce pressure, and when the pressure difference reaches the preset lower limit value, the fan is turned off.
