Smart Sensors

CALDEV International is part of the CALDEV Group of companies. We develop sensors and systems for the maritime industry, Aerospace, Automotive, HVAC, Industrial Automation, mobile devices, Medical technology, Internet of things, smart homes, smart Energy etc solving energy optimization and measurement of emission gasses. Our sensor products are based on patented technology and are ideally suited for the global focus on energy efficiency and the environment. Our products are designed for the maritime environment, and they are extremely robust and can precisely and continuously measure climate parameters and environmentally harmful gases and thereby provide valuable input for energy optimization. The Dynamic Ventilation System provides significant energy savings for container vessels carrying reefers below deck. The system automatically optimizes the cargo hold ventilation based on CO2 and temperature sensors. Typically 10-15% of the combined energy to reefers and cargo hold ventilation is saved.

CALDEV offers electrostatic precipitators design and modeling. Engineering and consulting services in electrostatic technology and air pollution control. CG offers also product and custom solutions for data acquisition and process control: measurements, sensors, customs automated systems. CG successfully operates in the design of data acquisition and measurement systems for industrial applications: manufacturing tests, measurements, functional testing. CG offers also consulting and engineering services in the field of air pollution control, combustion flue gas and electrostatic precipitation.

Environmental Sensing opens up new possibilities to create smarter devices that improve our comfort and well-being as well as increase energy efficiency in a wide variety of applications.


CG's sensors are used in a wide range of markets and different applications. Our high-quality sensors and sensor solutions for the measurement and control of humidity, gas and liquid flows improve energy efficiency and sustainability. They increase our safety, support our health and raise the quality of life.

In many markets, CG's years of experience and continuous innovation have made us the market leader. Again and again, CG sets the standard in markets around the world. Through science and innovation we enable our customers in nearly every industry to meet the current and future needs.

Heating, Ventilation and Air Conditioning (HVAC)

The technical infrastructure of buildings and the accurate measurement of environmental influences form the basis for a pleasant indoor climate. Using CG’s proven sensor solutions, we help ensure energy-efficient operation of family homes, industrial facilities, and entire building complexes also increasing the level of comfort. Often, the interrelationships in buildings are particularly complex, so that finding the right parameters to measure is very difficult.

With our extensive knowledge of sensor technology and many years of experience in the HVAC industry, we make our customer’s products more energy efficient, more competitive and bestsellers in the indoor climate market. For example, our differential pressure sensors ensure optimum heat recovery from the exhaust air of buildings, thus substantially minimizing energy consumption. Today, our sensor technology can reduce a building's current energy consumption by 10 percent.
