Description
242 = Custom-defined RTD PtX a=0.003850 (X factor of Pt1)
243 = Custom-defined RTD NiX a=0.006180 (X factor of Ni1)
244 = Custom-defined RTD CuX a=0.004270 (X factor of Cu1)
245 = Custom-defined RTD PtX a=0.003916 (X factor of Pt1)
Physical upper limit function of sensor1 (e.g. Pt 100 = 850°C) and
input range.
The unit of UPPER_SENSOR_LIMIT is the
PRIMARY_VALUE_UNIT.
Physical lower limit function of sensor1 (e.g. Pt 100 = -200°C) and
input range.
The unit of LOWER_SENSOR_LIMIT is the
PRIMARY_VALUE_UNIT.
Physical lower limit function of sensor2 (e.g. Pt 100 = -200°C) and
input range.
The unit of LOWER_SENSOR_LIMIT is the
PRIMARY_VALUE_UNIT.
Physical upper limit function of sensor2 (e.g. Pt 100 = +850°C) and
input range.
The unit of UPPER_SENSOR_LIMIT is the
PRIMARY_VALUE_UNIT.
