Temperature, Humidity, Pressure Sensor
Humidistat is designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc. Transmitter is equipped with two relay outputs for alarm indication or control of external devices. Each relay can be assigned to any measured or computed value. For each relay setting of delay, hysteresis, an audible alarm is enabled.
Measured temperature and relative humidity are recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy. Parameters are easily adjustable from regulator keyboard or from the computer. Large dual line LCD for simultaneous display of temperature, relative humidity, or other calculated humidity interpretation is an advantage.
State-of-the-art capacitive polymer sensor ensures excellent calibration long-term stability, inertia against water, and condensation. Transmitter is designed for use in a non-aggressive environment.

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.
