Analog input
Measuring input Pt1000 according to DIN EN 60751, in 3-wire circuit
Operating temperature range -30 to +260 °C for basic type 902930/10 and 902930/20;
-50 to +600 °C for basic type 902930/12 and 902930/22;
-200 to +600 °C for basic type 902930/50 and 902930/60;
Observe the admissible ambient temperature range for the case.
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
Probe 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, can be configured customer-specific
Transmission interval Adjustable from 1 to 3600 s:
for basic type 902930/10, 902930/12, and 902930/50 (factory setting = 10 s);
Adjustable from 5 to 3600 s:
for basic type 902930/20, 902930/22, and 902930/60 (factory setting = 15 s)
Radio frequency 868.4 MHz (Europe);
915 MHz (America, Australia, Canada, and New Zealand);
Ten frequencies can be set in the 915 MHz frequency band.
Transmission power
<
+10 dBm
Open air range 300 m for 868.4 MHz, 100 m for 915 MHz
and 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.
Output signal 882.2 to 1977.1 ohm ־ -30 to +260 °C; 185.2 to 3137.1 ohm ־ -200 to +600 °C;

Configuration With setup program
Configurable parameters Transmitter detection (max. 5-digit ID), transmission interval, radio frequency (only at 915 MHz)
Voltage supply
Lithium battery Voltage: 3.6 V, rated capacity: 2.2 Ah
for basic type 902930/10, 902930/12, and 902930/50;
Voltage: 3.6 V, rated capacity: 1.7 Ah
for basic type 902930/20, 902930/22, and 902930/60
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
