AUTOMOTION COMPONENTS LTD

Accurate temperature measurement is the foundation of any building control system. ACI has temperature sensors to fit every application and meet the most demanding specifications. Our temperature sensors are double-encapsulated to ensure durability. ACI has the manufacturing flexibility to produce unique solutions for all volume needs.

ACI humidity sensors are durable, accurate, reliable, and backed by a five-year warranty on the entire device. They can be field calibrated to reduce operating costs and paired with a temperature sensor to reduce installation costs.

ACI’s wet and dry media pressure sensors ensure your building operates at the highest level of efficiency. Multiple models have user-configurable options to maximize application flexibility.

ACI’s current sensor line includes sensors, switches, relays, and power meters. We have the technical knowledge to solve the most challenging applications and to ensure your installation is on time and on budget.

For toxic and combustible gas, as well as refrigerant leak detection, ACI’s line of gas sensors will solve the most challenging applications with the fewest devices and lowest total installed cost

Interface devices convert one type of control signal to another saving time and money by extending the life of existing field devices. 

ACI’s wireless system is based on MESHNET 900TM MHz spread spectrum technology. This system integrates seamlessly with any building automation system and is suitable for a wide variety of applications. Please contact us and we can help design your system.

BACnet™ MS/TP and Modbus RTU communicating sensors provide an easy-to-install and cost-effective means to measure temperature and humidity anywhere on your network. They are especially effective when controller inputs are limited or for monitoring-only applications. All BACnet™ sensors are BTL Certified.

ACI power meters can reduce energy consumption through predictive maintenance, identification of underperforming equipment, calculation of ROI, and many other measurements. They can communicate with a BMS or work as stand-alone data loggers. ACI has the technical knowledge to ensure your installation is on time and on budget.

Controlling IAQ is critical to maximizing building performance and occupant health/safety. ACI sensor solutions for IAQ include VOC and PM (volatile organic compound and particulate matter), CO2, temperature, and humidity with options to fit every application.

ACI offers additional products such as freeze stats, smoke detectors, power supplies, light level sensors, leak detectors, mounting clips/brackets, and others. Please contact us for technical and application support.

Complete solutions for temperature, humidity, pressure, and current sensors as well as freeze stats and switches to cover all aspects of AHU applications.

Sensors play a crucial role in chiller systems by providing valuable data for monitoring, control, and optimization. Here are some common sensor applications in chiller systems:

Indoor air quality (IAQ) is a major concern to businesses, schools, building managers, tenants, and workers because it can impact the health, comfort, well-being, and productivity of the building occupants.

Critical facilities like data centers require high accuracy and tight tolerances. Temperature, humidity, pressure, and current sensors all play a role in ensuring 24/7 uptime.

Proper control in your retail refrigeration applications can maximize energy efficiency and minimize loss while leak detection can ensure the safety of customers and employees.
