Product Description:
This series of wireless digital pressure gauges is a battery-powered low-power/wireless digital output digital pressure gauge, which can be equipped with 4G, LORa-iot, and NB-iot wireless communication protocols.
The built-in laser welding pressure sensor can accurately display the pressure in real time, and has the characteristics of high accuracy and good long-term stability.
This digital pressure gauge is equipped with a large LCD display, a built-in MCU, and a low-power design to realize wireless transmission of the on-site pipeline pressure to the cloud.
The product adopts 304 joints and full cast aluminum housing, and has passed the intrinsically safe explosion-proof certification. Good shock resistance, capable of measuring gas, liquid, oil and other non-corrosive media to stainless steel.
The product has practical functions, real-time display of current pressure, upload rate is adjustable from 1 minute to 24 hours, high and low pressure alarm points can be preset, and it has two functions: event uploading and timing uploading.
It is especially suitable for fields that require unattended and remote monitoring, such as fire water pipe network, fire terminal, fire pump house, urban water supply, petrochemical industry, etc.
Technical characteristics:
4G/LORaWAN/NB-iot optional
TCP/UDP/MQTT/Coap multiple protocols are optional
The combination of timing message + event message to ensure timely alarm
Support Bluetooth configuration and remote parameter configuration to reduce maintenance costs
Cast aluminum explosion-proof shell, sturdy and durable, beautiful product
Posting interval, adjustable by button, can be set from 3 minutes to 24 hours
