The complete redesign of Siemens’ room sensor range focuses on Indoor Air Quality (IAQ) as the main focus, with the introduction of a traffic light system to enable any issues to be identified at a glance.

Many IAQ sensors indicate levels of carbon dioxide parts per million in a given environment. However, without information on what constitutes the ideal level in terms of air quality, this can be virtually meaningless. This has led to the introduction of a simple yet powerful tool to address this challenge: CO2 traffic light sensors, with a green, amber or red light indicating good and bad air quality levels in real time.

“There are many applications where this would be of real benefit in ensuring improved air quality,” says Ron Purcell, Product Manager at Siemens Buildings. Taking education as an example, there have been many studies highlighting how poor air quality can have a detrimental impact on learning ability. Research suggests that keeping CO2 levels below 1,000 ppm can increase productivity by between 2 and 18%. However, it is unreasonable to expect a teacher to have an in-depth understanding The understanding or time needed to constantly monitor CO2 levels, while a simple red light provides an immediate alert that air quality is poor and it is time to open a window or improve air circulation through the building’s building management system. This visual signal enables building occupants to take control of their environment without the need for technical expertise, promotes awareness and behavior change, and encourages proactive ventilation habits that improve indoor air quality without relying solely on automated systems. Faster intervention to ensure air quality is maintained and does not negatively impact the health of patients or residents.

The new visual indicators are just one feature in the redesign of Siemens’ next generation of room sensors which include temperature, relative humidity, carbon dioxide and TVOC (total volatile organic compounds) sensors. Available in black and white options for all models, the new range offers improved aesthetics, touchscreen displays for easier changing of measurements, mobile apps for easier configuration and higher sensor accuracy.

Siemens has recently introduced what it claims is one of the world’s most innovative circuit protection devices. Here we learn more about the SENTRON ECPD.

Using advanced electronic switching technology, the SENTRON ECPD (Electronic Circuit Protection Device) electronically turns off circuit faults in the event of faults and, if necessary, trips the mechanical insulating contact downstream. Until now, disconnections were handled only by electromechanical elements.

SENTRON ECPD enables completely new approaches to electrical planning, increasing safety and flexibility and providing huge space and energy savings compared to traditional solutions. Its features and benefits include:

1. Multifunctional

The SENTRON ECPD intelligent device provides additional functions in a single compact design, saving space and costs. The function set can be customized as needed with new functions that can be easily activated on the SENTRON ECPD device without the need to purchase a new device and adapt it functionally to the circuit.

The unit can be modified as needed and is perfectly adapted to the application requirements, in terms of rated current, tripping limits or behaviour. These characteristics provide major planning and cost advantages.

For example, circuits can be designed simply based on the loads’ rated current rather than the significantly higher inrush current peaks that occur briefly with certain types of loads, such as LEDs.

This reduces complexity as well as planning and installation efforts and the provision of materials such as copper.

2. Ultra fast

In the event of a short circuit, SENTRON ECPD is claimed to disconnect up to a thousand times faster than conventional circuit breakers, reducing the short circuit energy.

The product also provides corrosion-free replacement, which increases the service life of the systems and reduces maintenance and repair costs. In addition, the integrated periodic self-test (including integrated RCD function) takes safety to a whole new level.

3. Reduce operating costs and downtime

SENTRON ECPD provides complete transparency regarding power consumption in the final circuit through wireless communication with SENTRON Powercenter 1000 and 3000 gateways. This allows measurements to be made to improve systems and processes, which in turn allows for effective reductions in energy and operating costs.

Uniquely, detailed monitoring of application status is possible at the downstream circuit level, significantly increasing availability and operational reliability.

The large volume of measurement data allows detection of irregularities and deviations and creates a reliable planning basis for preventive maintenance. The module can be easily integrated into higher-level systems using the open Modbus TCP standard.

SENTRON ECPD enables remote diagnostics and remote switching during normal operation as well as in the event of a fault. This offers significant benefits, especially for remote applications without direct on-site support. In addition, faults are easier to locate and identify by distinguishing the cause of the fault.

4. Sustainable

SENTRON ECPD combines multiple product functions in one device, which is 90% lighter than conventional devices and requires up to 80% less space in the distribution board, eliminating the need for costly structural procedures.

“With this product launch, it is now possible to leverage many functions in a single product and activate them according to the individual application requirements or adapt them if necessary. All this, combined with solid-state switching technology, enables fast switching of up to 1,000 times without wear,” said Andreas Matte, CEO of Siemens Intelligent Infrastructure Electrical Products.
