Temperature Indicators
Longscale Indicators to read temperature values, usually remotely with RTD or
thermocouple sensors supplied by the customer. RTD (Resistance Temperature
Detector) indicators measure the change in resistance of the sensor. A 2 or 3 wire
system may be used. Thermocouple indicators accept standard millivolt input
signals. Cold junction compensation is provided and thermocouple break indication
is incorporated.
