- The operation of the gas microhumidity meter GTV-002 is based on the ability to sorb water molecules by the moisture-sensitive layer of the humidity sensor.
- A special temperature sensor and a sorption-capacitive humidity sensor are used as primary sensors.
- A change in the amount of water sorbed in the sensitive layer leads to a change in the electrical capacitance of the humidity sensor, which is converted into a frequency signal, measured and converted into a digital code displayed on a digital display.
- The test gas is fed into the chamber through a collet fitting using a flexible hose and is removed from the chamber through the outlet fitting.
- Before entering the chamber, the gas passes through a filter that cleans the gas from mechanical and oil particles. The gas flow is regulated by turning the knob located on the side wall. The gas exits the chamber through the outlet fitting.
- Within a certain time, an equilibrium is established in the chamber between the moisture content in the analyzed gas and its content in the moisture-sensitive layer of the sensor.
- The equilibrium moisture content in the moisture-sensitive layer of the sensor determines its electrical capacitance, and, as a result, the output frequency measured using the indication and measurement board.
- Individual calibrations that establish the functional relationship between the frequency of the sensor, the temperature of ice sublimation (dew point temperature) and humidity are entered into the memory of the computing device of the board and are automatically used in the measurement process.
- Temperature measurement is provided by a special temperature sensor, the signal from which is immediately issued in a digital code.
|
- The device is made in a single housing, which houses the measuring chamber, indication and measurement board, battery or battery. The chamber contains a humidity sensor and a temperature sensor.
- With the help of the indication and measurement board, the signals from the temperature and humidity sensors are processed and the processing results are displayed on a digital display located on the front panel of the meter housing.
- On the front wall there is a "MODE" button used to select the following measurement modes: temperature, relative humidity, dew point, displayed on a digital display.
- There is also a button "BACKLIGHT", which serves to illuminate the display. To save consumption, the backlight turns on for a few seconds. To turn it on again, press the button again.
- On the side wall there is a switch to turn the device on and off.
- To prevent unauthorized opening, the device is supplied with a special seal located on one of the fixing screws on the rear side of the device, or a sticker with the inscription “GTV” that closes the joint of two parts of the case and which is destroyed when the device is opened.
- If the case is opened, the integrity of the seal or sticker will be broken.
- If the hygrometer or any part of it fails, the device must be completely replaced.

DEVICE AND OPERATION OF THE DEVICE
Hygrometer GTV-002 is a microprocessor temperature and humidity meter. A special temperature sensor and a capacitive humidity sensor are used as primary sensors. The device consists of a housing containing a measuring chamber, an indication and measurement board, and a battery. The chamber contains humidity and temperature sensors. The indication and measurement board processes signals from temperature and humidity sensors and displays the processing results on a display located on the front panel of the meter housing.
On the front wall there is a "MODE" button used to select the following measurement modes: temperature, relative humidity, dew point.
There is also a button "BACKLIGHT", which serves to illuminate the display. To save consumption, the backlight turns on for a few seconds. To turn it on again, press the button again.
On the side wall there is a switch to turn the device on and off. The operation of the device is based on the ability to sorb water molecules by the moisture-sensitive layer of the humidity sensor. A change in the amount of water sorbed in the sensitive layer leads to a change in the electrical capacitance of the humidity sensor, which is measured and converted into a digital code displayed on a digital display. Temperature measurement is provided by a special temperature sensor, the signal from which is immediately issued in a digital code. The test gas is fed into the chamber through a collet fitting using a flexible hose.
Before entering the chamber, the gas passes through a filter that cleans the gas from mechanical and oil particles. The gas flow is regulated by turning the knob located on the side wall. The gas exits the chamber through the outlet fitting. The indicator has a symbol, serial number, release date. The hygrometer is packed in a cardboard box.
