HTS201

The HTS201 room sensor is dedicated for accurate and reliable measurement of relative humidity (RH) and temperature (T) in residential and commercial building automation. The elegant enclosure is available in two sizes (EU and US format) and features an optional display.

HTS201 features

Outstanding Measurement Performance
The E+E RH / T sensing element with proprietary protection ensures excellent long-term performance of the HTS201 over the entire working range and even in dusty and dirty environment. The innovative enclosure avoids false air ingress and significantly reduces self-heating.

Outputs and Digital Interface
The RH and T measured data is available either on two analogue outputs, or on the RS485 interface with Modbus RTU. In the digital version, the HTS201 also calculates the dew point temperature (Td). The measured values can also be read locally on the optional graphic display.

The version with RS485 interface can be set up and configured via PC with the free PCS10 Product Configuration Software and an optional configuration adapter.

Installation-friendly Enclosure
The enclosure of the HTS201 facilitates fast and thus cost-saving installation. The back cover with the push-in spring terminals can be mounted and wired without the front cover. This means that the electronics, which are accommodated in the front cover, are not exposed to construction site pollution. Before commissioning, the active part can be simply snapped onto the back cover. Besides, the electronics part can be replaced without tools within seconds.

FAQ

Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
