Welcome at our website!

Our company is grounded at 1949 in Berlin Germany. The name Rüster stands for High Quality and Service since the start of the company.

Rüster develops and manufactures a wide range of sensors and transmitters for Industrial and HVAC proposes. With our new line of products we decided that it was time to show the world our Unique solutions for HVAC applications.

Our products are not only Innovative and High Quality but also excellent priced!

Rüster building controls is a part of Paul Rüster & Co GmbH

Paul Rüster & Co.GmbH

Paul Rüster & Co GmbH grounded in 1949 in Berlin Germany by Paul Rüster. Rüster is from the start of the company well known as developer and manufacture of innovative and High quality pressure transmitters, resistance thermometers for control of motors and generators, humidity sensing etc (with or without EX approval)

In our industrial delivery program there is a wide range of EX sensors and transmitters, sensors and transmitters special developed for sea going vessels, trains and offshore etc. All these solutions can be ordered with or without calibration!

Our success as a producing company is largely a function of how quickly it responds to new market requirments. Therfore our working methods are state of the art. In certain areas we cooperate closely with Universities, Institutes and partners.

Paul Rüster & Co GmbH is a ISO 9001 approved company.

Rüster carbon dioxide sensors 

With the introduction of our new primeline housing and the "multi-board" we also introduce the next generation carbon dioxide sensors.  

Air quality In offices, schools, hotels, conference rooms etc is the monitoring and control of the air polution an important part of the comfort control system.

Rüster provides not only a high accuracy and long term stability with our CO2 sensing solutions but also a innovative and high quality solution! 
How does a NDIR sensor actually work?

NDIR is an industry term for "nondispersive infrared".
An infrared (IR) lamp directs waves of light through a tube filled with air towards an IR light detector, wich measures the amount if IR light. As the light passes through the tube , any gas molecules that are the same size as the wavelength of the IR light absorb the IR light only, while letting other wavelengths of light pass through.

NDIR sensor
Next, the remaining light hits an optical filter that absorbs every wavelength of light except the exact wavelength absorbed by CO2. Finally, an IR detector reads the amount of light that was not absorbed by the CO2 molecules or the optical filter.
The differance between the amount of light radiated by the IR lamp and the amount of IR light recieved by the IR detector is measured. The differance is proportional to the number of CO2 molecules in the air inside of the tube.

Duct sensor "Primeline"

KCO2T carbon dioxide room sensors

The KCO2T series of duct mounted carbon dioxide sensors are supplied with a 0..2000ppm CO2 sensor and a active temperature output. 

Optional the sensor is available with 0..5000ppm CO2 sensor, passive temperature outputs, humidity or tri-colour LED /Display.

Using a non-dispersive infrared sensor for measuring Co2

Concentrations and utilizing microprocessor based electronics, the unique self-calibrating algorithm offers long-term stability and accuracy.
The sensor can be used to ensure adequate ventilation while maximizing energy savings by ventilating at the optimum level, making these ideal for all types of ventilation in commercial buildings, industrial plants, laboratories and public places, such as schools.
