All your measurements are stored in the data logger then transmitted by radio to a PC or to the Newsteo Cloud
LGS31 : Characteristics
Ref. 221-PFPN-LGS31-001
Input : 1 input Potentiometric mounting
Measurement Range : 1 kOhm … 65kOhm
Accuracy : Total sum of the errors : 1LSB max meaning ±3×10-3% (using Newsteo transfer functions)
Resolution : 1LSB (corresponds to the full scale of the sensor divided by 32768)
Response time : 0,15s, Maximum measurement speed : 1s
Operating temperature : -40°C to +85°C
Other sensor : Integrated temperature sensor on the electronic card.
Radio range : Up to 900 meters (with supplied antenna)
Memory Capacity : Up to 32 768 measurements with date and time
Measurement frequency : Can be set from one measure every second to one every 4 hours
Measurement securisation :
- Acknowledgment process between the transmitter and the receiver to ensure that no data is lost during radio transmission
- Back-up of the last 36.000 measurements in Logger memory even after transmission to the receiver
Sensor connection :
- either via the connector already integrated into the probe (probes supplied by Newsteo),
- either via a connector or a cable to be ordered from Newsteo (for the customer’s probes).
Battery :
- AA Lithium Thionyle (3,6V) included, special design with plug to maintain the battery
- Accessible and user replaceable battery
- Optional: dual battery pack to double battery life 3 ans
Autonomy : - Assessed at a measurement frequency of every 10 minutes, at 25°C.
- Average value which may vary according to use.
- Value given without switching to product alert mode.
Power supply for the sensor : 2.7V /150mA max
