Performance
Operating conditions
Accuracy
(±3s = range including 99.7% of the readings, |t| = absolute value of the temperature in °C)
Transmitter maximum error: See the corresponding documentation (codes at the end of the document).
Display maximum error: 0.1% FSR + 1 digit (FSR = Full Scale Range).
The "4 wires" configuration, provided as a standard connection for the single Pt 100s, excludes additional
errors in every condition (e.g. high immersion depths, long connecting cables without head-mounted transmit-
ters, ...).
Generally speaking, in the "4 wires" configuration there is a higher guarantee of accuracy.
Response time
Tests in water at 0.4 m/s (according to DIN EN 60751; 23 to 33°C step changes):
Insulation
Insulation resistance between terminals and probe sheath
> 100 MOhm at 25°C
(according to DIN EN 60751, test voltage 250 V)
> 10 MOhm at 300°C
Self heating
Negligible when the E+H iTEMP® transmitters are employed.
