Outdoor measurement points need a logger that can stay close to the sensor and still feed data into the wider monitoring system. This wireless data logger family records environmental and process-related values on site, stores them in internal memory and transmits them to the HD35AP base unit automatically or on request.
Model options cover temperature, humidity, atmospheric pressure, rainfall, solar radiation, level, leaf wetness, soil volumetric water content, particulate matter and WBGT index. External probes connect via M12 connectors, cable glands or terminal inputs depending on version, giving the system practical flexibility for meteorology, agriculture, hydrology, photovoltaic monitoring and outdoor industrial sites.
The polycarbonate housing is designed for outdoor installation, with IP 67 or IP 53 protection depending on model. Wall mounting or mast fixing is supported with optional accessories, and RF range in open field reaches 300 m or 180 m with internal antenna, or >500 m with external antenna where available.
Models use M12 connectors, cable glands or terminal headers for external probes and sensor connections, depending on version.
The family includes versions for temperature, humidity, pressure, rainfall, solar radiation, level, leaf wetness, soil water, PM and WBGT.
Measurements are stored in the internal memory and transmitted to the base unit automatically at set intervals or on request.
Outdoor models are available with custom LCD, except PM models, which are available without display.
LCD versions display measured values, connection status, battery charge level and RF information for installation checks.
