5.1 Technical data
Analog input
Measurement input Pt1000 according to DIN EN 60751, in three-wire circuit
Operating temperature range -30 to +260 °C
Accuracy
of the temperature sensor Class A ±(0.15 K + 0.002 × ItI)
ItI = measured temperature in °C without prefix sign
Sensor line resistance ≤ 11 ohm per line for three-wire circuit
Sensor current ≤ 500 µA
Measuring circuit monitoring Detection of probe break and probe short circuit
Output (wireless transmission)
Transmitter detection (transmitter
ID) Max. 5-digit ID, factory-set, not configurable
Transmission interval Adjustable via DIP switch: 5 s, 10 s, 20 s, or 45 s
(default setting = 20 s)
Radio frequency 868.4 MHz
Transmission power < +10 dBm
Open air range 300 m and use of receiver
antenna holder for wall mounting and 3 m antenna cable.
When mounting the antenna directly to the receiver, a reduction in the range of
approx. 40 % must be taken into account.
Output signal 882.2 to 1977.1 ohm = -30 to +260 °C

Voltage supply
Lithium battery Voltage: 3.6 V, rated capacity: 2.2 Ah ( Symbol for direct voltage)
Operating life Approx. 1 year with the factory-set values and at room temperature (a fast
transmission interval and a high or low ambient temperature reduce the battery
operating life)
Battery change Only use the preconfigured lithium battery that is available as an accessory
(part no. 00525539)
