Online temperature, humidity, barometric pressure transmitters are designed for use in exacting interiors in building energy management and HVAC systems. Are designed for easy installation on ordinary KU68 wiring boxes for household switches and sockets.
Large dual line LCD for simultaneous display of temperature, humidity or barometric pressure is an advantage. Display is possible to switch off.
Computerized design ensures temperature compensation of the humidity and pressure sensors and fail indication. Transmitters are designed for use in non-aggressive environment.
Measured value is converted to digital serial output with the RS485 link parameters. Transmitter circuitry is galvanically isolated from power circuitry to prevent collision in RS485 network. 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 online readings and modify transmitter configuration. Sensor works always in slave mode, i.e. responds only to master device query.
