Refrigeration Sensor Types & Locations

Monitoring variables such as temperature, humidity, current, lead detection, and pressure is essential to every facility’s refrigeration operation in order to ensure quality control and prevent spoilage.  If temperatures rise, the shelf life of food can be affected, and food can ultimately go bad.  ACI offers a range of sensors optimized for retail refrigeration, providing reliable and accurate readings to ensure an efficient refrigeration process.  This guide demonstrates sensor types and ideal locations, and it is designed to help you find the right sensing solution.

Common Challenges

Retail refrigeration presents a number of challenges for the control system. 

  • Valuable inventory and profits can spoil if proper temperatures are not maintained   
  • Costly compressors and equipment can fail if not properly maintained 
  • Refrigerants can leak and are hazardous to employees and customers 

The ACI Solution

ACI offers a wide variety of highly accurate sensors for every application and for every location in your facility.

  • Building pressure sensors control airflow within a facility for optimal heating a cooling efficiency  
  • Refrigerant pressure sensors help ensure pumps and compressors are operating at peak efficiency  
  • Power meters are used for preventative maintenance to keep freezers and coolers operating at maximum uptime
