Output Scale; Output Signal Limitation - E+E Elektronik EE371 Manual

Output scale; Output signal limitation

The Td analogue output can be scaled within the range -100...80 °C (-148...176 °F).
For air (gas) temperature Ta ≤20 °C (≤68 °F), the output is limited at Td = -80 °C (-112 °F)
For air (gas) temperature Ta >20 °C (≤68 °F), the output is limited at Td = Ta -100 °C (Ta-180 °F)
Example (see also Fig.1):
For air (gas) temperature Ta = 30 °C (86 °F) the output is limited at Td = 30°C -100 °C = -70°C (86°F –
180°F = -94 °F).
