Humidity and temperature sensor DVT-304

The company "REGMIK" produces humidity and temperature sensors DVT-304 with analog sensing element. In sensors DVT-304 Honeywell element is used as a sensitive element for humidity measurement. For temperature measurement the temperature sensors of the German company Heraeus are used.

Humidity sensor DVT-304 is used in systems of automated regulation and control of technological processes in industry. Also in systems of control and monitoring of microclimate of premises, in drying chambers. The protective cover of the sensor is made of foamed stainless steel particles with fine porosity, which does not oxidize.

As a result, the sensing element is protected from small dust particles and from splashes falling in any direction. In the event of resin, sawdust, dirt, etc. adhering to the protective cover, the protective cover can be carefully removed and washed in solvent. However, it must be dried before reinstallation.

Humidity and temperature sensors are designed to convert the value of the relative humidity of the gas environment and its temperature (except for aggressive gases) into standard electrical signals:

• analog voltage (measured voltage value at the humidity sensor);
• І2С - digital sensors;
• voltage 0-10V - for digital and analog sensors;
• current 4-20mA - for digital and analog sensors;
• resistance (temperature value from a Pt100, Pt500 or Pt1000 temperature sensor) - for analog sensors;
• RS-485 (ModBus RTU protocol) - for digital sensors.

The area of application of air humidity_sensors is very wide and includes:

• Maintaining a microclimate within specified limits in a production equipped with moisture-sensitive electronic devices;
• Control over the indicators of humidity in office premises, in everyday life;
• In the field of housing and communal services - in boiler rooms and at water treatment plants, they prevent the formation of condensate;
• Periodic control helps to prevent the appearance of mold, mildew on the walls of the building or in the warehouse;
• Control of technological processes;
• Monitoring of environmental parameters, etc.

The material of the protective armature of the sensors is stainless steel of 12Х18Н10Т grade. Humidity and temperature sensors DVT-304 do not allow moisture condensation.

The multi-layer construction of the moisture sensor element provides superior resistance to most application hazards such as wetting, dust, dirt, oils and common chemicals in the environment. Key features of Honeywell element-based sensors:

• Molded body made of thermosetting plastic;
• Almost linear output voltage versus relative humidity;
• Interchangeable with laser fit;
• Low power design;
• Increased accuracy;
• Fast response time;
• Stable performance with low drift;
• Chemical resistance.

The transmitter operates stably within the recommended measuring range for humidity and temperature. Prolonged exposure to conditions outside the normal range, especially humidity> 80%, may temporarily increase measurement uncertainty. Once returned to normal range, it will slowly revert to factory settings.

Special care must be taken when using the transmitter in humid conditions (> 98%) and near the dew point as if wet, the sensing element can be irreparably damaged.
