Features

Temperature transmitter and thermostat 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. For each relay setting of delay, hysteresis, audible alarm is enabled.
Measured values are converted to galvanically isolated RS485 serial output.
Degrees Celsius and Fahrenheit are user selectable.
Parameters are easy adjustable from regulator keyboard or from the computer. Large dual line LCD display is an advantage.
Transmitter is also equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact.

APPLICATIONS

  • temperature control
  • monitoring of temperature and three binary signals at:
  • building management and automation
  • server rooms
  • telecommunication devices
  • warehouses, glasshouses
  • manufacturers
  • museums, archives, galleries
  • air-conditioned rooms, HVAC

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. 

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.
