Sensor

1 or 2 RTD sensors (PT100) connectable

Maximum measurement range

±0.2 °C (-200 °C bis 850 °C) without Pt100

Reproducibility measurement channel

+/- 0.1°C (measurement range -100 °C to +200 °C of the channel) with the logger at 23 °C ambient temperature

NOTE:

The reproducibility of the PT100 sensor is to be added still.

Reproducibility measurement channel

for maximum range

+/- 0.2 °C (measurement range -200 °C to +850 °C of the channel) with the logger at 23 °C ambient temperature

NOTE:

The reproducibility of the PT100 sensor is to be added still.

Operation time of the battery

The batteries of RMS devices typically last 3 years under the optimal conditions:

•Temperature = 20°C±5°C.

•Wireless signal strength >-60 dBm.

•Limited “read out data” events in the audit trail.

Log memory

44000 of measurement for each channel

Startup time logger

< 10 s

Measurement interval

>= 10 s

Adjustment

1 or 2 point per channel

Sensor quality

•Detection of short circuit on the sensor connectors

•Detection if no sensor connected

Temperature simulator function for validation

Fix values for each channel

Operational temperature logger

-40 ... 70 °C

Storage temperature

-40 ... 30 °C

NOTE:

Small storage temperature range is based on the battery life
