6.1 Technical data
Analog input
Measuring input Pt1000 according to DIN EN 60751, in 3-wire circuit
Operating temperature range -30 to +260 °C
Accuracy
of the temperature sensing ele-
ment Class A ±(0.15 K + 0.002 × ItI)
ItI = measured temperature in °C without prefix
Sensor lead resistance ≤ 11 ohm per lead with 3-wire circuit
Sensor current ≤ 500 µA
Measuring circuit monitoring Detection of probe break and probe short-circuit
Output (radio transmission)
Transmitter detection
(transmitter ID) Max. 5-digit ID, factory-set, cannot be configured
Transmission interval Adjustable via DIP switch to 5 s, 10 s, 20 s, or 45 s
(factory-setting = 20 s)
Radio frequency 868.4 MHz
Transmission power < +10 dBm
Open air range 300 m and use of the receiver
antenna wall holder, and 3 m antenna cable.
When installing the antenna directly on the receiver, the user must
take approx. 40 % less range into consideration.
Output signal 882.2 to 1977.1 ohm = -30 to +260 °C

All accuracy specifications in % relating to the measuring range of 290 K.
Voltage supply
Lithium battery Voltage: 3.6 V, rated capacity: 2.2 Ah
Operating life Approx. one year with the factory-set values and at room tempera-
ture (a fast transmission interval and a high or low ambient temper-
ature reduce the battery operating life)
Battery change Only use the preconfigured lithium battery that is available in the
accessories (sales no. 90/00525539)
