Delta Ohm HD35 wireless data loggers

Click2Contact

Delta Ohm has released an additional series of loggers for the HD35 wireless data logger system.

The loggers cover parameters including solar radiation, soil temperature and WBGT index. These loggers supplement the existing range of relative humidity, atmospheric and differential pressure, wind speed and direction, illuminance (lux) and UV radiance, solar radiation, CO, CO₂, rain and acceleration loggers.

Additionally, a version is available for standard process sensors including PT100 and thermocouple temperature sensors, 4–20 mA and voltage signals.

All remote units have an integral memory of up to 74,000 readings and a secure robust wireless system with RF interference checking and automatic channel selection within the wireless operating band to ensure error-free transmission, as well as optional repeaters to extend the wireless range. Data is retained even after it has been sent to the base unit until the memory is full — the logger can then be programmed to stop logging or overwrite the older data.

An IP67-rated outdoor version of all data logger transmitters is also available.

Base units can handle up to 254 data loggers and versions are available with USB PC interface and an integral GSM module, RS485 and Modbus outputs, and a Wi-Fi version is also available with USB and Ethernet outputs utilising an existing Wi-Fi and local network.

Applications include the monitoring of storage for food and pharmaceutical products; environmental monitoring; laboratory and clean room monitoring; fridge and freezer monitoring; and industrial process logging.
