Umidistatele sint proiectate pentru controlul bipozitional al incalzirii, ventilatiei, umidificarii si dezumidificarii, etc. .
Transmitterul este echipat cu doua iesiri cu relee pentru indicarea alarfmei sau controlul dispozitivelor externe. Fiecare releu poate fi atribuit oricarei valori masurate sau calculate. Pentru fiecare releu se pot seta intirzierea, histerezisul sau alarmarea. Transmitterul complet echipat contine senzori de temperatura, umiditate si presiune. Temperatura masurata si umiditatea relativa sint recalculate in alte interpretari ale umiditatii – temperatura punctului de roua, umiditatea absoluta, umiditatea specifica, raportul de amestec sau entalpia specifica.
Citirea si iesirea de presiune sint disponibile in urmatoarele unitati de masura: hPa, kPa, mbar, mmHg, inHg, inH₂O, PSI, oz/in². Afisarea in grade Celsius sau Fahrenheit este selectabila de către utilizator. LCD-ul mare dual pentru afişarea simultană a temperaturii, presiunii sau umidităţii relative sau a altei interpretari calculate a umidităţii este un avantaj.
Parametrii sint usor de setat de la tastatura transmitterului sau de la calculator.
Senzorul de ultimă generaţie cu polimer capacitiv asigură o stabilitate excelentă pe termen lung, inertie impotriva apei şi condensare. Transmitterul online este proiectat pentru utilizarea în medii non agresive.
Transmitterul poate fi echipat optional cu trei intrari binare pentru detectarea evenimentelor cu diua stari – de exemplu prezenta apei, fumului, spargerea geamurilor, contact deschidere usa, etc..

Figure: Humidistat working range

Serial output RS485 is galvanically isolated from other circuitry to prevent collisions on the RS485 bus. The transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 0 to 255. Communication speed is 110 to 115200Bd.

Free program SensorReader for logging values from one transmitter via RS485 to a PC disk file is ready to download. Program enables to alarm acoustically the PC user if adjusted alarm limits are exceeded. Recorded values in CSV format are easy to process in e.g. Excel. Program can be started several times on a computer at the same time to monitor values from several transmitters.

Included accessories:

Traceable calibration certificate from the manufacturer, instruction manual. Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.

Free program TSensor for configuring of the transmitter is ready to download.

For acquiring values from several transmitters connected to RS485 bus, third party software is necessary to use. Tested functionality is with programs:

LabVIEW from National Instruments, TIRS.NET, ControlWeb, EasyView.
