Humidity and temperature sensor DVT-001, DVTts-001

The REGMIK enterprise produces humidity and temperature sensors with digital (DVTts-001) and analog (DVT-001) sensing elements. In DVT-001 sensors, the HIH4xxx element is used as a sensitive element for measuring humidity, in DVTts-001 sensors, an SHTxx element. Temperature sensors from the German company Heraeus are used to measure temperature.

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 fittings of the sensors is stainless steel 12X18H10T. Humidity and temperature sensors DVT-001, DVTts-001 prevent moisture condensation.

The multi-layer design of the HIH4xxx sensing element provides excellent resistance to most application hazards such as wet, dust, dirt, oil and common environmental chemicals. Main characteristics of sensors based on elements of the HIH4xxx series:

• 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.
