Reliable and Flexible Cold Chain Monitoring Solution with PT100 Temperature Sensor

The cold chain ensures that the food, beverages, medication, and volatile chemicals are still safe to use after they reach the consumers. To do this right, temperature is a profoundly vital factor. Bacteria grows quickly and could taint consumable goods if the transporters do not keep them at the right temperature. Cold rooms, warehouses, order assembly points and loading docks all have specific temperature profiles that must be monitored and maintained based on the products being stored or transported. Adopting a reliable and accurate PT100 temperate sensor may be one of the best ways to ensure the efficacy and safety of temperature-sensitive products.

Why PT100

The PT100 temperature sensor is an instrument that converts temperature variables into a standardized output signal that can be transmitted. They have been used for many years to measure temperature in cold chain, laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability. 

  • Control at Specific Level

Cold chain Logistics service providers need to offer controlled environment, refrigerated, frozen, deep freeze and cryogenic freezing services, which can be complex as each has its own temperature requirements and application.

  • Maintenance in Transit

Shipments pass through a variety of environments and handlers. Considering any deviations in temperature could affect the safety of products, it’s difficult to manage complicated cold chain effectively without real-time information.


An industrial temperature monitoring system for cold chain can be useful on any type of equipment with moving parts and components. At Linovision, we offer two workable solutions tailored to customers’ needs. For new LoRaWAN solution deployment, the IOT-S500PT Industrial Temperature Sensor would be a good candidate. It is a three-wire RTD design and performs perfectly as cold as -328 °F (-200 °C). By transporting data from IOT-S500PT to IOT-G65 gateways, real-time monitoring and alerts of temperature on Cloud platform are achievable easily. For upgrades to existing deployments, the IOT-C300 IoT Controller could be a better fit. Besides the 4~20 mA and 0~10 V type analog interfaces, the IOT-C300 firstly adopts 2 RTD inputs for accepting and converting resistance signal of 2/3 wires PT100 sensors into 4-20 mA current signal with a range from -200°C to 800°C. Besides, IOT-C300 IoT Controller supports 4G and LTE. So, the selection of technology would be more flexible.
