Funkcionalnost
Merilniki delujejo lahko kot dataloggerji ali pa direktno pošiljajo podatke spejemni enoti prek kratkih radijskih valov - brezžično. Njihov domet je 150 m, za podaljšanje pa lahko uporabimo repetitor. Prenos podatkov je samodejen glede na nastavitve oz. ko je sprejemik v dosegu. Vsi merilniki 501 in 502 imajo 16.000 spominskih točk.
Delovanje celotnega sistema je mogoče tudi pod ničlo in sicer do -40°C pa tja do +80°C. Kar pa ne pomeni, da ni mogoče še dlje, le s pomočjo podaljšanih merilnih sond.
Equipped with an internal temperature sensor, the RTR-501 features the highest waterproof and dustproof capability. This is the perfect Data Logger for use in harsh environments: whether that may be indoor frozen or refrigerated storage or high humidity, high dust outdoor applications. Moreover, the compact lightweight design means it can be placed just about anywhere.
Download Data via Wireless Communication with a Base Unit
Recorded data can be downloaded from RTR-501/502/503/574 Data Loggers (Remote Units) via wireless communication with a Base Unit.The wireless communication range between a Remote Unit and a Base Unit is about 150 meters [500 ft].By registering an RTR-500 as a Repeater, it can be used to expand the wireless communication range.
Large Storage Capacity: Up to 16,000 Readings
RTR-501/502: Maximum of 16,000 Readings
16,000 readings means you can record every one second and still log four and a half hours of data; or at a recording interval* of 60 minutes you can keep logging for 666 days. A Base Unit can download via wireless communication one RTR-501 or RTR-502 Remote Unit at full storage capacity (16,000 readings) in about two minutes.
Low Energy Consumption Design
RTR-501/502/503
The RTR-501, RTR502, and RTR503 Data Loggers use one Lithium Battery (LS14250). At normal temperature, if recorded data is downloaded once a day or if monitoring is carried out once every ten minutes, the estimated battery life will be about ten months.
Model names which include “L” are designed with a large capacity battery pack. Under the same conditions, L-type models will continue for about four years without the need to change the battery.
