Technical data
Basic type 902930/15, 902930/17 and 902930/55
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 element 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 when using the antenna wall holder for the receiver and the 3 m long antenna cable.
When installing the antenna directly on the receiver, a reduced range of approx. 40 % must be
taken into account.

Voltage supply
Lithium battery Voltage: 3.6 V, rated capacity: 2.2 Ah
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
will reduce the operating life of the lithium battery)
Battery change Only use the preconfigured lithium battery that is available in the accessories
(Part no. 00525539)
Environmental influences
Ambient temperature range of the case -30 to +85 °C (case including electronic components)
If the operating temperature exceeds the max. ambient temperature, take into account the heat
input of the protection fitting into the case. For detailed information, please refer to operating
manual B902930.0.1 in the chapter "Heat input by protection tube/protection fitting“.
Storage temperature range -40 to +85 °C (case including electronic components)
Temperature influence
≤
±0.0025 % 1 /K; per K deviation from the reference temperature 22 °C (±3 K) (case)
Resistance to climatic conditions Rel. humidity
≤
95 % w/o condensation according to IEC 68-2-30
Vibration resistance Max. 2 g at 10 to 2000 Hz (relating to the case including electronic components)
according to DIN IEC 60068-2-6
Admissible mechanical shock resistance 25 g/6 ms (relating to the case including electronic components)
according to DIN IEC 68-2.29 per 1000 cycles
