The enterprise "REGMIK" produces humidity and temperature sensors with digital (DVTc-001) and analog (DVT-001) sensitive elements. In the DVT-001 sensors, an HIH4xxx element is used as the sensitive element for humidity measurement; in the DVTc-001 sensors — an SHTxx element. German Heraeus temperature sensors are used for temperature measurement. Humidity and temperature sensors are designed to convert the value of relative humidity of a gaseous environment and its temperature (excluding aggressive gases) into standard electrical signals: analog voltage (measured voltage value on the humidity sensor); I2C – digital sensors; 0-10 V voltage – for digital and analog sensors; 4-20 mA current – for digital and analog sensors; resistance (temperature values from Pt100, Pt500, or Pt1000 temperature sensors) – for analog sensors; RS-485 (ModBus RTU protocol) – for digital sensors. The field of application for air humidity sensors is very wide and includes: Maintaining the microclimate within specified limits in production environments equipped with devices sensitive to humidity; Monitoring humidity indicators in office premises and households; In the housing and communal services sector – in boiler rooms and water treatment plants to prevent condensation; Periodic monitoring helps prevent the formation of mold and mildew on building walls or in storage; Control of technological processes; Monitoring ecological parameters, etc. The protective fittings material of the sensors is stainless steel grade 12X18H10T. The humidity and temperature sensors DVT-001, DVTc-001 do not allow moisture condensation. The multilayer design of the HIH4xxx sensitive element ensures excellent resistance to most adverse factors such as wetting, dust, dirt, oils, and common chemical substances in the environment. Main features of sensors based on HIH4xxx elements: Cast thermosetting plastic case; Practically linear output voltage depending on relative humidity; Interchangeability with laser trimming; Low power consumption design; Increased accuracy; Fast response time; Stable characteristics with low drift; Chemical resistance. Humidity and temperature sensors DVT-001, DVTc-001 based on SHTxxx elements have the following distinctive features: High reliability and long-term stability; Proven technology with experience of more than 10 years; Designed for mass production; Optimized for minimal cost; Low noise signal level. The converter operates stably within the recommended range of humidity and temperature measurements. Prolonged exposure to conditions outside the normal range, especially at humidity > 80%, may temporarily increase measurement errors. After returning to the normal range, it will gradually return to factory parameters. Special caution should be taken when using the converter in conditions of high humidity (> 98%) and near the dew point, as wetting may permanently damage the sensitive element. Other modifications of humidity sensors are also produced, which can be viewed at the link...
