MD-S270G wireless digital pressure gauge (dual power supply type) Introduction
The MD-S270G digital pressure gauge is a battery-powered, low-power/wireless digital output digital pressure gauge with optional GPRS or LORa-iot wireless communication.
This model can be powered by dual power supply, usually power supply, and will automatically switch to battery power after power off.
Built-in high-precision pressure sensor for accurate real-time pressure display with high precision and long-term stability.
This digital pressure gauge is equipped with a large LCD display, built-in MCU, low power design
The product uses 304 stainless steel housing and joints, and is certified by intrinsically safe explosion-proof. It has good shock resistance and can measure gas, liquid, oil and other media that are non-corrosive to stainless steel.
The product function is practical, the current pressure is displayed in real time, the uploading rate is adjustable from 1 minute to 24 hours, and the alarm point can be preset. Once the alarm pressure is triggered, the alarm data will be sent in time.
It is especially suitable for fire-fighting pipelines, fire-fighting end, fire pumping stations, petrochemicals and other fields that require unattended and remote monitoring.
At present, the products have been used in batches for the Shanghai fire hose network monitoring system.
