MD-270 wireless digital pressure gauge Introduction
This series of wireless digital pressure gauges is a battery-powered, low-power/wireless digital output digital pressure gauge with optional GPRS, LORa-iot, and NB-iot wireless communication protocols.
The built-in laser welding type pressure sensor can accurately display the pressure in real time, and has the characteristics of high precision and long-term stability.
This digital pressure gauge is equipped with a large-size LCD liquid crystal display, built-in MCU, low-power design, and realizes wireless transmission of on-site pipeline pressure to the cloud.
The product adopts 304 joint and fully cast aluminum casing, 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, the high and low pressure alarm points can be preset, and there are two functions of event sending and timing.
It is especially suitable for fire hose network, fire end, fire pump room, urban water supply, petrochemical industry, etc., which need unattended and remote monitoring. Features
