Refrigerated Truck Temperature Monitor

【Refrigerated Truck Temperature Monitor Detection Principle】: Refrigerated Truck Temperature Monitor can monitor the temperature and humidity of refrigerated trucks in real time and transmit the data wirelessly.Using digital temperature and humidity sensors,the thermal resistor and humidity sensor are packaged into a small chip,and the full range multi-stage calibration is used,and the calibration data is stored in the chip.

【Temperature and Humidity Sensor】: Imported sht30

[Material material of the whole machine]: Carbon-poly high-strength shell,waterproof and dustproof on the operating buttons,firm and reliable;

[Full machine appearance]: Humanized button design; exquisite appearance,showing grandeur;

【Complete machine size】: 122mm*102mm*36mm

[LED display]: With display screen,support Chinese menu display,4-inch large screen display,real-time display of data,temperature and humidity alarm prompts,the instrument can be equipped with multiple temperature and humidity acquisition,and the number of channels can be customized according to customer actual needs;

[Password Protection]: The device keys are equipped with password protection function to prevent non-administrators from tampering with parameters.

【Communication Interface】: Built-in mobile communication module uploads data to the cloud platform,built-in SIM card,SIM card has industrial-grade SIM card,which has high temperature resistance,vibration resistance,electromagnetic interference resistance,moisture resistance,corrosion resistance and other characteristics.You can choose according to your needs Equipped with 2G and 4G versions.The device can configure device parameters through the TCP/IP protocol stack through the SMS command.

[Installation method]: Installation of wall-mounted hoist holes (spacing 77mm,rotary hole diameter 5mm) or buckle installation (spacing 170mm)

[Power supply method]:

①.10-30vdc wide voltage power supply.The power plug is suitable for power plugs and can be adapted to the output of 5.5mm*2.1mm*11mm or 5.5mm*2.5mm*11mm DC round hole plug.

②,10-30vdc wide voltage power supply,terminal power supply

③.Dual power supply design,the instrument has a built-in rechargeable lithium battery,which can still work normally in the event of power outage,so you don’t need to worry about the instrument not working properly in the state of power outage.The metering process is convenient and there is no need to carry a power supply.

【Maximum power consumption】: 0.7W

【Default Accuracy】: Humidity ±3%RH (60%RH,25℃); Temperature ±0.5℃ (25℃);

【Transmitter circuit working temperature】: -40℃~+60℃,0%RH~80%RH

[Probe working temperature]: -40℃~+120℃ Default: -40℃~+80℃

【Probe working humidity】: 0%RH-100%RH

【Temperature display resolution】: 0.1℃

【Humidity display resolution】: 0.1%RH

【Temperature and humidity refresh time】: 1s

【Long-term stability】: Humidity ≤1%RH/y; temperature ≤0.1℃/y

[Response Time]: Humidity ≤8s (1m/s wind speed); temperature ≤25s (1m/s wind speed)

[Data upload interval]: 5s~24h can be set.

[Data recording interval]: The data storage interval can be set according to customer needs,and 1 min-60 min can be set arbitrarily;

[Data record frequency conversion function]: Once the temperature exceeds the standard,the monitoring system software synchronizes the alarm,and the system automatically switches to record data every 2 minutes (the frequency conversion interval can be set by itself).

[Data Continuation Function]: In case of network failure,the equipment has the data retransmission function to ensure the integrity of the data.It comes with data storage function (memory ≥50,000 records).When the server goes down,the device can store the received real-time data by itself and automatically upload the stored data when the network is restored.

[Equipment Management Function]: Users can obtain online and offline information of the device through the management software platform.The software has extensible open functions,which can meet the needs of future project system expansion;

[Battery Life]: In the absence of power supply and data uploaded once in 20 seconds,the mains power can last for more than 48 hours after power is cut off.
