New room sensor generation by E+E Elektronik

Tailored to the respective facility automation application, the CDS201 3-in-1 device for CO2, humidity and temperature, the HTS201 humidity and temperature sensor and the TES201 temperature sensor are great choices. Each variant has analogue outputs or a digital interface and a large, state-of-the-art display. The functional Snap-on enclosure minimises installation costs and avoids the intake of false air.

Measurement, performance, design

The three sensors impress with their outstanding accuracy in terms of the physical quantities. This results from E+E Elektronik's many years of experience in the production of high-quality sensing elements.

On top of this, the elegant, functional snap-on enclosure design is exciting and available in two sizes (EU and US versions) depending on regional standards. The lower part of the housing only contains the plug-in terminals and can be installed and connected without the cover, which contains the electronics. This means that the active part of the device is not exposed to any contamination and can be fitted on the lower part shortly before commissioning. The innovative enclosure also prevents the ingress of false air and significantly reduces self-heating. The sensors are optionally available with a state-of-the-art, easy-to-read graphic display.

Interfaces and configuration

The measured values are either delivered via analogue outputs or to the digital interface using the Modbus RTU or BACnet MS/TP protocol. The digital version with its RS845 interface can be set up and configured on a PC using the free PCS10 product configuration software and an optional configuration adapter.

Areas of application

The new room sensors are highly suited for use in demand-driven ventilation, heating and air conditioning technology, and facility automation.

CDS201 – The versatile choice

The CDS201 combines CO2, temperature (T) and relative humidity (RH) measurement in a single device and is particularly well suited for demand-driven ventilation and facility automation in residential and commercial applications.

The CDS201's CO2 measurement relies on the contamination-resistant NDIR dual-wavelength principle. This technology automatically compensates for aging effects, while at the same time guaranteeing excellent long-term stability. Factory multi-point CO2 and temperature adjustment ensures high measurement accuracy over the entire temperature operating range.

E+E sensor coating protects the active RH/T sensing element against contamination and corrosive deposits. This results in improved measurement performance and longer sensing element life in environments with high levels of dust or soiling exposure. In addition, it improves long-term stability by preventing stray impedances caused by deposits on the active sensor surface.

HTS201 – The allrounder

The HTS201 is designed for accurate and reliable measurement of relative humidity (RH) and temperature (T) in residential and commercial facility automation applications.

The E+E RH/T sensing element with its patented sensing technology guarantees excellent performance over the entire operating range even in environments with high levels of dust or soiling exposure. Again, E+E sensor coating ensures long-term stability for the measurements.

TES201 – The efficient choice

The TES201 is designed for accurate room temperature measurement (T) for indoor climate control. In addition to proven, high-quality E+E sensing technology, these room sensors impress with their great price/performance ratio.
