The measuring instrument of humidity and temperature of IVT-2 grain from the producer
The measuring instrument is used:
- For measurements in burta on currents, barns, warehouses, at acceptance of grain crops on elevators, mills, complexes of processing of various seeds;
- For control of grain in a storage time;
- For control of humidity of seed material;
- For control of humidity of grain at its sending for procuring points, etc.
The measuring instrument is efficient under following conditions:
ambient temperature is from 0 °C to +50 °C;
relative humidity of air to 90%.
Range of measurement of temperature - from 0 °C to +50 °C
Absolute error of measurement of temperature no more than 1 °C
Range of measurement of humidity from 5% to 35%
Absolute error of measurement of humidity of grain:
from 8% to 17% no more than ±1,5%
from 17% to 35% no more than ±2,5%
Hold time of the converting block in grain at measurement of temperature not less than 1,5 min.
Depth of immersion of the converting block - from 0,25 to 0,9 m
Supply voltage - 9B "Krone"
Power consumption is no more than 0,05 W.
Overall dimensions - 1120х95х40 mm
Weight is no more than-2,5 kg
The principle of work at measurement of temperature is based on change of resistance of a thermosensitive element of the block depending on the change of ambient temperature measured by an electric circuit of the device.
The principle of work of measurement of humidity is based on measurement of capacity of the converter of the condenser depending on change of humidity of grain.
Digital indication with direct counting of the measured size on ZhKI - the display. Structurally the measuring instrument of humidity consists of the converter of temperature, humidity, a bar and the measuring block.
