Description

The Senseca HD2021T Series consists of photometric and radiometric transmitters designed to convert measured light and radiation quantities into standard analog output signals.

The series supports the measurement of illuminance in lux as well as irradiance in W/m² across different spectral regions, including VIS-NIR, UVA, UVB, and UVC. Depending on the selected configuration, the transmitters can provide either a 4–20 mA output or a 0–10 V DC output.

The instruments are suitable for installation both indoors and outdoors, making them appropriate for a wide range of monitoring, control, and automation applications.

Available models include:

HD2021T – for illuminance measurement;
HD2021T1 – for VIS-NIR irradiance measurement over the 400–1050 nm spectral range;
HD2021T2 – for UVA irradiance measurement; this model has been discontinued;
HD2021T3 – for UVB irradiance measurement;
HD2021T4 – for UVC irradiance measurement.

The series can be used for illuminance control in offices, manufacturing plants, production areas, commercial premises, theatres, museums, sports facilities, roadway lighting, tunnels, and nursery or greenhouse systems.

The HD2021T1 is intended for monitoring solar radiation in the 400–1050 nm range. The UVA and UVB models can be used to monitor irradiance from tanning lamps and to evaluate the efficiency of filters in equipment using high-pressure lamps. The HD2021T4 is designed for UVC irradiance monitoring, for example in wastewater treatment systems where the efficiency of UVC lamps must be continuously monitored.

The HD2021T Series is suitable for applications requiring continuous photometric or radiometric measurement and transmission of the measured signal to control, automation, or data acquisition systems.
