Photo Amplifier for DVO, IVO, RVO

The software and hardware complex with a set of sensors for physics classrooms is designed to measure physical quantities during demonstration work on various sections of physics, as well as to perform experimental work on physics. The set of units of the measuring system is compatible with a PC, has software with an instruction manual. The sensor kit includes 10 sensors for measuring the following physical quantities: - temperature sensor DTV-1 (measuring range -200C + 1100 S); - air humidity sensor DTV-1 (measuring range 10-100%); - pressure sensor DD-1 (measuring range 0-700 kPa); - acceleration sensor DUIMP-1 (measuring range - 4 – + 4 g); - permanent magnetic field induction sensor DUIMP-1 (- 8 – + 8 Gs); - illumination sensor DSCH-1 (measuring range 1 -60 000 lux); - distance sensor DR-1 (measuring range 0.04 – 4.0 m); - angular velocity sensor DUPUS-1 (remote) (measuring range 0 – 210 0/ c); - rotation angle sensor DUPUS-1 (measuring range ±3600); - flame temperature sensor DTP-1 (measuring range 100 – 11000 S).

Mathematical processing of the measurement makes it possible to determine and display on the indicator board the relative systematic change in frequency, the average relative value of the frequency difference, the RMS relative frequency deviation, the RMS relative two-sample frequency deviation.
