Performance Specifications
GRT1-TS2P/TS2PK
Note
For the GRT1-TS2P, a current of 0.35 mA flows to the platinum re-
sistance thermometer. For the GRT1-TS2PK, a current of
0.035 mA flows to the platinum resistance thermometer.
Note
A 2-wire connection has a strong affect on the conductor resistance. When
using a 2-wire connection, the conductor resistance
R
directly determines the
error.
GRT1-TS2P: The error will be 4
°
C/
Ω
for each line. For example, when using a
conductor with a resistance
R
of 1
Ω
, the total conductor resistance would be
1
Ω ×
2 = 2
Ω
. Therefore, an error of 4
°
C/
Ω ×
2
Ω
= 8.0
°
C would occur.
GRT1-TS2PK: The error will be 0.4
°
C/
Ω
for each line. For example, when
using a conductor with a resistance
R
of 1
Ω
, the total conductor resistance
would be 1
Ω ×
2 = 2
Ω
. Therefore, an error of 0.4
°
C/
Ω ×
2
Ω
= 0.8
°
C would
occur.
