Description

Humidistats are 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, audible alarm is enabled.Measured values are converted to galvanically isolated RS485 serial output or RS232 output.

Wireless data acquisition system via GSM can be built easily with Comet software package Database Sensor Monitor. Fully equipped transmitter contains temperature, humidity, pressure sensors. Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy. Reading and pressure output are available in these units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2.Degrees Celsius and Fahrenheit are user selectable.

Parameters are easy adjustable from regulator keyboard or from the computer. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitter is designed for use in non-aggressive environment.

Transmitter is also equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact. Transmitter is equipped with internal terminals for powering of connected external detectors.
