Product overview
EL33xx-00x0 20 Version: 4.2
2.1.2 Technical data
Technical data EL3311 EL3312 EL3314
Number of inputs 1 2 4
Thermocouple sensor types Types J, K, L, B, E, N, R, S, T, U, C (default setting type K), mV measurement
Input filter limit frequency 1 kHz typ.; depending on sensor length, conversion time, sensor type
Connection technology 2-wire
Maximum cable length to
the thermocouple
30 m (see note [
}
31] )
Measuring range, FSV in the range defined in each case for the sensor (default setting: type K; -200 … +1370°C)
Voltage: ± 30 mV (1 µV resolution) up to ± 75 mV (4 µV resolution)
Resolution Internal: 16 bit
Temperature representation: 0.1/0.01 °C per digit, default 0.1°C
Note: 16 bit is used for FSV calculation; so, value leaps >0.01°C will occur at resolution 0.01°C depending
of which thermocouple is set; e.g. type K: approx. 0.04°C
Supports NoCoeStorage
