Illuminance, luminance, radiant illuminance, equivalent luminous flux transmitter / HD2021T
Senseka (formerly Delta Ohm)
Illuminance, luminance, radiant illuminance, equivalent light curtain luminance transmitter
The HD2021T series converts light and radiation amounts in the UVB and UVC spectral regions and the wavelength range of 400 to 1050 nm into signals of 0-10V or 4-20mA, represented as illuminance (lux), luminance, equivalent light curtain luminance (cd/m²), or irradiance (W/m²). These analog outputs are calibrated to the specified full-scale values before shipment. ▼ Analog output DC 4-20mA or DC 0-10V ▼ Three types of output scaling available ▼ Suitable for outdoor use (IP66 model) ▼ Equivalent light curtain luminance measurement (HD2021T7)
