Cold Chain Temperature & Location Monitoring

Frequently Asked Questions

How does the Cold Chain Temperature & Location Monitoring Solution calculate ambient box temperatures and track movement during transit?

The device integrates a precision semiconductor bandgap or platinum RTD (PT100/PT1000) thermal sensing element that converts minute temperature-dependent electrical changes into accurate digital readings across a wide thermal spectrum of -40°C to +85°C. Simultaneously, the unit activates its onboard GNSS/GPS engine to obtain live satellite fixes, recording exact geographic coordinates, vehicle movement status, and instantaneous speed. An internal microcontroller aggregates these environmental and spatial datasets, encrypts the payload using AES-128 algorithms, and broadcasts the frame over licensed LTE Cat-M1 cellular networks directly to the Ellenex Software Platform for decoding and visualization.

What mounting method is recommended when installing the tracker inside a reefer trailer or refrigerated container?

The IP66 UV-stabilized transmitter enclosure can be permanently fastened or magnetically secured directly onto internal side walls, cargo bulkheads, or door frames using specialized mounting brackets. For installations requiring extended probe lengths, such as deep inside palletized stacks or far from the doorway, an external RTD probe (like the PT1000 option) is routed directly into the core cargo area. This layout allows the primary transmitter housing to be mounted on an upper frame or door edge where cellular and GPS RF signals penetrate metallic container walls most effectively.

What sets RTD PT100 and PT1000 sensing elements apart for cold chain monitoring applications?

The solution accommodates both Class-B RTD PT100 and PT1000 sensing options depending on the physical geometry of the transport container. A PT100 element operates with a nominal resistance of 100 ohms at 0°C, delivering high precision for standard ambient logging and short-wire runs. The PT1000 element utilizes a base resistance of 1000 ohms at 0°C, which significantly reduces the proportional impact of lead-wire resistance over extended cabling lengths. Consequently, the PT1000 is strongly recommended when routing long sensor cables across expansive multi-zone reefer trailers to maintain measurement accuracy without signal attenuation.

How does the Ellenex Software Platform handle temperature excursion alerts when a cooling compressor fails mid-route?

The Ellenex Software Platform houses a highly configurable, multi-channel alerting and rules engine. Operations managers define rigid upper and lower temperature boundaries tailored to specific cargo profiles, such as maintaining strict 2°C to 8°C limits for temperature-sensitive biopharmaceuticals or frozen thresholds for ice cream. If an HVAC compressor trips, power drops out, or a reefer door remains open, causing internal box temperatures to cross set limits, the platform instantly triggers automated emergency notifications via SMS, email, and mobile application push alerts. This allows dispatchers to contact drivers immediately, reroute vehicles, or activate backup refrigeration systems before cargo spoilage occurs.

Why is LTE Cat-M1 chosen over local gateways for mobile transport and logistics tracking?

Refrigerated transport assets, express delivery vans, and intermodal containers travel continuously across regional highways and inter-state corridors where fixed private gateway infrastructure cannot be deployed. LTE Cat-M1 is a licensed 3GPP cellular LPWAN technology embedded within the 5G massive IoT framework, offering extended cell tower reach and superior signal propagation through metal vehicle structures. Furthermore, Cat-M1 natively supports active cell-tower handovers, ensuring uninterrupted telemetry and continuous GPS tracking while transport assets move at high highway speeds between regional distribution centers.

How does the platform assist logistics companies in settling cargo damage claims with insurance underwriters?

The platform automatically generates tamper-evident, time-stamped digital audit ledgers that synchronize continuous temperature logs directly with GPS position maps along the entire transit route. If cargo arrives damaged or spoiled, logistics operators can export comprehensive route reports showing exact historical timelines. These detailed data logs enable managers to pinpoint the precise location, time, and duration of any thermal excursion, conclusively proving whether a refrigeration failure occurred during carrier transit or prior to loading, thereby streamlining insurance claim resolutions and mitigating liability disputes.

What battery management strategy supports up to 5 years of operation in moving refrigerated vehicles?

The monitoring unit is powered by an internal, field-replaceable 3.6V Lithium primary battery (LiSOCl2) known for its high energy density and exceptional thermal stability in cold storage environments. Operating on ultra-low-power firmware algorithms, the device remains in an energy-conserving deep sleep state between reporting cycles. At scheduled intervals (such as every 15 or 30 minutes), the processor briefly wakes up, captures sensor readings, secures a GPS position lock, transmits the encrypted payload, and returns to sleep. This optimized power management scheme enables field operation for up to 5 years without requiring external vehicle wiring or charging maintenance.
