Multi-sensor Modbus AMS06-MODBUS LCD

The maintenance-free microprocessor-controlled AMSxx-MODBUS measuring device combines a large number of measured variables in various possible combinations. It is the perfect device to realize a demand-oriented air conditioning considering the relevant measured variables. Possible are combinations for the measurement of humidity & temperature, carbon dioxide, carbon monoxide, air quality (VOC), fine dust, atmospheric / barometric air pressure and differential pressure.

The detection range of the sensors is designed for standard applications of HVAC technology for the monitoring of residential and conference room, workplace and production facilities. However, special designs, other measuring ranges and measured variables can also be implemented on request. Ventilation according to demand, increase of well-being and customer benefit, increased comfort as well as a reduction of operating costs by energy saving are only some results of the use of this compact device. The high quality housing series BoCube® with hinge lock technology and the approx. 4 inch graphic LCD display perfectly match the design and quality standards of this device. Configuration (bus address, transmission mode, baud rate, etc.) is carried out conveniently and quickly via a self-explanatory menu. Via corresponding registers, fine adjustments of individual measured variables, the initiation of VOC and/or CO2 calibrations and changes to the display can be made, among other things.
