Multi-Sensor Measuring Device with up to 8 sensors for surface mounti, 813,42 €

This multi-sensor measuring device can be individually assembled from the following measured variables: temperature, humidity (also heated), air pressure, differential pressure, air quality (CO, CO2, VOC, O2, fine dust), flow, oxygen, paticulate matter, brightness and movement. This Sensor Platform provides a compact, multi-talent for capturing key environmental conditions in a single instrument with more than 200 configuration options. The digital output is available as Modbus RTU and on-board relay for further signal processing. The high-quality housing series with the new hinge closure technology offers optimal space for the multi-sensor platform. External sensors are safely protected from external influences by aluminum / stainless steel fittings. A 4 inch backlight graphic LCD display visualizes all measured values and also serves to configure the measuring devices using the user menu. The multi-sensor measuring devices are ideal for use in workplaces, production facilities, warehouses, medical facilities or in industry. For the optional relay output, the switching threshold and hysteresis can be set using a register. Also for the optional display, adjustments such as display content, orientation in 90 ° increments, mode of the backlight, etc. can be specified per register. As special equipment a potential-free alternating contact and/or a backlit display are available The contents of the display can be rotated in steps of 90° by using a command. As special functions a series of defined measured values from other bus-participants (also cross-manufacturers) can be shown in the display. To display measured values from other bus-participants these are entered into the corresponding register by the bus-Master. The optional alternating contact can be configurated for measured values from other bus-participants. The configuration of address, transmission mode/speed, terminating resistor and master/slave function of the bus-devices can easily be done using the innovative DIP switch technology. Thus devices can quickly and easily integrated into the system and later parameterised via the master. The bus-devices can even be reset to the works settings during operation of the master. Thus the basic functionality of the device is recreated in a matter of seconds. This can be necessary in the event of incorrect parameterisations of, e.g. offset, switching threshold, display modes etc.. By means of the FS master/slave topology autarkic nodes without additional SPS master can be installed within the device series. Hereby a bus-device assumes the master function in the node. This requests the measured values from other bus-participants, automatically enters these into the corresponding register and shows them in the internal display. Furthermore the master can evaluate and operate additional actuators in the device series (analogue in- and outputs, relay station).
