Description
Comet T7318
- Contains a microprocessor-based control circuitry
- Large dual line LCD
- Computerized design ensures temperature compensation of the humidity sensor and fails indication
- Inertia against water and condensation
Interior Temperature, Humidity, Bar. Pressure Transmitter, RS232 Output
Degrees Celsius and Fahrenheit are user selectable. Transmitter contains a microprocessor based control circuitry in a plastic case with connection terminals and sensors. Large dual line LCD for simultaneous display of T+RH or other humidity interpretation is an advantage. Display is possible to switch off. Computerized design ensures temperature compensation of the humidity sensor and fail indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitters are designed for use in non-aggressive environment.
For exacting interiors in building energy management and HVAC systems. Are designed for easy installation on ordinary KU68 wiring boxes for household switches and sockets.
Measured values are converted to RS232 serial output. Serial output RS232 – 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.
