Combined device TKA-PKM is designed to measure the following:
— air relative humidity;
— air temperature;
— air motion velocity;
— illumination in the visible spectrum (380−760 nm);
— irradiance in the spectral range (200−280) nm -UV-C, (280−315) nm -UV-V, (315−400) nm -UV-A;
— brightness of extended self-luminous objects and the rate of illumination pulsation.
Among other options, TKA-PKM device displays estimated readings calculated on the base of measured parameters: temperature values of a humid thermometer, temperature of the dew point, index of the heat load in the environment (TNS-index), average radiation temperature, and the density of heat radiation flow.
TKA-PKM device is used in the following areas: sanitary and engineering supervision in residential and production premises, museums, libraries, archives; attestation of work places and other activities.
The operating principle of the device is about conversion of optical radiation into a photo flux by the photo detector, as well as conversion of physical parameters of the environment using a moisture sensor, a sensor of the air motion velocity, and a temperature sensor into an electrical signal, with further processing and indication of measurement results and calculations.
The combined device TKA-PKM is produced in a compact portable make. On the housing of the instrument, there are the following items: an LCD indicator, controls, marking labels, and a remote probe with sensors of measured parameters. Depending on the composition and number of measured parameters, the probe can be installed either on the housing of TKA-PKM device, or on the probe head connected to the main housing by means of a communication cable. Photo detector cells with corrective filters which form the spectral characteristics of channels are in the probe head.On the rear wall of the signal processing unit, there is a battery compartment lid.
