Product Overview
The ADDA-P-WX wireless pressure transmitter uses diffused silicon piezoresistive, corrosion-resistant ceramic capacitive, or corrosion-resistant ceramic piezoresistive sensors. This high-stability, high-reliability wireless instrument is suitable for level monitoring in smart petroleum, smart water, smart heating, and smart fire protection applications. It uses ultra-low-power wireless communication and requires no signal wiring, enabling convenient installation.
Applications
1. Smart petroleum 2. Smart water
3. Smart gas 4. Smart heating
5. Smart fire protection
Product Features
Protection Grade: IP68, sealed waterproof design
Supports parameter configuration using local buttons or a remote device.
5-digit segmented LCD with a -30~70 degrees C operating temperature range. Displays pressure, battery level, wireless parameters, and other information.
Adjustable installation direction: connects to the field pipeline valve through a union or adapter, allowing the direction to be adjusted.
19Ah high-energy lithium thionyl chloride battery for long service life; optional battery and external power supply configuration.
High-gain antenna with a maximum wireless transmission distance of 2000m.
Supports private clouds and the matching cloud platform. Supports sending data to a specified IP address or website.
Ultra-low power consumption and a WDT watchdog design support stable long-term operation. Upper and lower alarm limits and dynamic-change thresholds can be configured; alarm information is reported immediately.
Supports data access through a mobile app and data reading by OPC configuration software.
