plMeasured parameters
TEMPERATURE MEASUREMENT:
APONE devices are designed to measure temperature using resistance temperature sensors (PT100 or PT1000) or digital temperature sensors. The measuring range and accuracy depends on the selected measuring device and/or probe.
HUMIDITY MEASUREMENT:
APONE devices are designed to measure relative humidity using integrated measuring elements or external humidity probes, which ensure high measurement accuracy and the possibility of future adjustment. Relative humidity measuring devices are designed to simultaneously measure the air temperature and determine other parameters, including dew point temperature, absolute humidity, ... (implemented psychometric calculation function). The measuring range and accuracy depends on the selected measuring device and/or probe.
CO2 CONCENTRATION MEASUREMENT:
APONE devices are designed to measure the concentration of carbon dioxide (CO2) in the range of 0 ... 10000 ppm CO2 (used in HVAC systems, BMS systems) or 0.04 ... 5% CO2 (used in chambers, incubators,…). CO2 concentration is measured using an NDIR sensor, which has an excellent long-term stability. Selected APONE devices can simultaneously measure CO2 concentration, relative humidity and air temperature - these are transmitters eagerly used in building automation.
ATMOSPHERIC PRESSURE MEASUREMENT:
APONE devices can also measure the atmospheric pressure. The digital pressure sensor used in these devices allows to simultaneously measure the air temperature. The APONE barometer is an ideal solution for BMS.
PRESSURE DIFFERENCE/FLOW MEASUREMENT:
APONE devices that measure the difference in pressure between air and neutral gases are based on the flow method (also known as thermal flow measurement). The advantage of these sensors is the lack of need for calibration (zero point), the measurement is independent in terms of temperature and atmospheric pressure. The measuring element is resistant to vibrations.
VOLATILE ORGANIC COMPOUNDS (VOC) MEASUREMENT:
APONE VOC devices measure the concentration of volatile organic compounds in the air. All measurement functions are provided by a high-class built-in digital sensor. It is an ideal solution for building automation systems (HVAC systems and BMS).
PARTICULATES (PM) MEASUREMENT:
APONE devices are designed to control the air quality in buildings by measuring the concentration of particulate matter. APONE PM transmitters simultaneously measure the concentration of PM1, PM2.5, PM4 and PM10. The measuring element built into the transmitters ensures high measurement stability.
ANALOG SIGNALS MEASUREMENT:
Selected APONE devices are designed to measure analog, voltage (0 ... 10 V) and / or current (0 ... 20 mA or 4 ... 20 mA) signals. APONE analogue signal converters have the function of filtering measurements (implemented continuous and averaging filters) and converting signals to any value, measured by the connected sensor. These devices make it possible to connect analog devices of other manufacturers to measurement networks (Modbus).
