8.1 Technical data
Analog input
Measuring input Pt1000 as per 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

(refers to the sheath up to approx. 20 mm beneath the handle)
Accuracy
of the temperature probe Class A ±(0.15 K + 0.002 x 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 short-circuit
Output (radio transmission)
Probe ID max. 5-digit ID, factory setting,
customer-specific configuration possible
Transmission interval adjustable from 1 to 3600 s;
factory setting
for basic type 902930/10, 902930/12 and 902930/50 = 10 s
factory setting
for basic type 902930/20, 902930/22 and 902930/60 = 15 s
Transmission frequency ISM band 868.4 MHz (Europe);
915 MHz (America, Australia, Canada and New Zealand);
ten frequencies can be set in the 915 MHz band
Transmission capacity < + 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 onto
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
810.6 to 3137.1 Ohm = -50 to +600 °C
185.2 to 3137.1 Ohm = -200 to +600 °C
