Refrigeration Sensor Types & Locations

Monitoring temperature, humidity, current, leak detection, and pressure are essential to every store’s refrigeration operation. If temperatures rise, food can spoil quickly or have its shelf life affected. ACI offers a range of sensors optimized for retail refrigeration. Our sensors provide reliable and accurate readings to ensure an efficient refrigeration process. This guide demonstrates sensor types, locations and 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 the proper temperature is 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 temperature sensors for every location in your store. Building pressure sensors can control airflow within the store for the best heating and 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.
