Model RTD-Z-6-.001 High Accuracy RTD Simulator

SPECIFICATIONS

The RTD Series Precision RTD

(Resistance Temperature Detector)

Simulator provides a very broad-

range of absolute resistance values.

The RTD simulator effectively re-

places an RTD to test, analyze, and

calibrate RTD measuring systems.

The RTD Series is ideal where appli-

ca ons of Resistance Temperature

Detector (RTD) simula on require

exact low value resistance without

“zero”andcontact resistanceeffects.

• Virtually independent of contact resistance

varia on

• Ideal for DIN PT-100, PT-100 ANSI, PT-50 and

NI-120 systems

Switch Setting:

The 10 Ω switch has two stops at positions

1 and 10. Absolute accuracy, without zero

subtraction, is accomplished by having a

minimum settable resistance, which includes

all contact and wiring resistances.

Absolute

accuracy applies for every setting. See table

above

for the minimum settable resistance

for any model. Minimum settable resistance

is implemented by a mechanical stop in one

of the decades.

Maximum Power for rated accuracy:

100 mW or 100 mA for 10.000 to 10.999 Ω;

100 mW per step for the highest decade in

use for 11 Ω and over.

Terminals:

Four, 5-way, gold-plated, tellurium-copper

binding posts with low thermal emf and

low resistance, for four-terminal Kelvin

measurements, plus one binding post

connected to case for shielding.

Connection to Terminals:

2 terminal devices: use H and L CURRENT

terminals

3 terminal devices: use H CURRENT - L

CURRENT

and G terminals;

4 terminal devices: use all CURRENT and

SENSE

terminals. (Note: Ground Strap is

the only connection between CURRENT and

SENSE

terminals.)

Switch type:

Multiple solid silver contacts; dust-tight

diallyl-phthalate body.

To allow continuous rotation, a blank position

is added on all decades except the 10 Ω

decade.

Resistor type:

Wirewound, hermetically sealed,

low-inductance

Maximum Current:

200 mA.

Breakdown Voltage:

1000 V.

Environmental conditions:

Operating temperature:

0ºC to 55ºC.

Storage temperature:

-40ºC to 70ºC.

Humidity:

<80% RH.
