Temperature Sensors
Reefer temperature sensors are essential for thermal control in refrigerated containers.
Temperature sensors for reefer containers
Temperature sensors for reefer containers are essential components to ensure the correct operation of the refrigeration system and maintain the thermal stability of the cargo.
These sensors allow the controller to precisely adjust compressor operation, fans and defrost cycles. A faulty sensor can cause incorrect readings, alarms or cold chain failures.
Types of reefer temperature sensors
In container refrigeration systems, the most commonly used sensors are thermistors, designed to provide accurate measurement at different points of the unit.
Sensors are typically installed at:
- Supply air
- Return air
- Evaporator
- Ambient/outdoor
When to replace a temperature sensor
It is advisable to replace sensors when the following symptoms appear:
- Incorrect temperature readings
- Recurring alarms on the controller
- Unstable operation of the refrigeration system
- Visible damage to wiring or connectors
