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.

Specification

Accuracy:

Class 1.5 - Indicator only. RTD indicator suitable for

10

Ω copper 100Ω platinum, 100 & 120Ω nickel sensors

Power in RTD is 100µW approximately. Thermocouple

indicator suitable for J (0-700°C), K (0-1200°C)

50

Ω maximum Circuit Resistance.

Auxiliary Supply:

Model 45R: from 63.5V to 480V A.C. at 50/60Hz

Model 45T: 110, 115, 220, 240, 380, 400, 480V A.C.

and 12, 24, 48, 110, 125V D.C.
