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, audible alarm is enabled.
Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.
Parameters are easy 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 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. 

HUMIDISTAT APPLICATIONS

  • temperature control
  • monitoring of temperature, humidity:
  • building management and automation
  • server rooms
  • telecommunication devices
  • warehouses, glasshouses
  • manufacturers
  • museums, archives, galleries
  • air-conditioned rooms, HVAC
  • weather stations

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 1 to 255. Communication speed is 110 to 115200Bd.

SOFTWARE:

  • Comet Database
    Complex solution for data acquisition and analysing. Easy to use and high flexible database software for Comet Transmitters and Regulators.


  • T-Sensor software
    Free configuration utility for Comet Transmitters and Regulators.

  • SensorReader software
    Basic data acquisition utility for Comet Transmitters and Regulators. Software is free for download.
