MD-S270 Wireless Digital Pressure Gauge (Dual Power Supply Type)
Dual power supply 4G/LORa/NB optional wireless digital pressure gauge
Product details
MD-S270G digital pressure gauge is a battery powered low-power/wireless digital output digital pressure gauge, with 4G or LORa iot wireless communication options.
This model can be powered by dual power sources, usually powered by a power source, and will automatically switch to battery power after a power outage.
Equipped with a high-precision pressure sensor, it can accurately display pressure in real-time and has the characteristics of high precision and good long-term stability.
This digital pressure gauge is equipped with a large-sized LCD display, built-in MCU, and low-power design
The product adopts a 304 stainless steel shell and joint, and has passed the intrinsic safety explosion-proof certification. Good seismic resistance, capable of measuring non corrosive media such as gases, liquids, and oils on stainless steel.
The product features practicality, real-time display of current pressure, adjustable upload speed from 1 minute to 24 hours, and preset alarm points. Once the alarm pressure is triggered, the alarm data will be promptly uploaded.
Especially suitable for fields such as fire pipelines, fire terminals, fire pump rooms, and petrochemicals that require unmanned and remote monitoring.
At present, the product has been widely used in the Shanghai fire water pipe network monitoring system.
