*1. A current of 0.35 mA flows to sensors connected to the DRT2-TS04P.
*2. The indicator accuracy specifications differ depending on the mounting direction. Refer to the above table for details.
In the DRT2-TS04T, a cold junction compensator is included in the Terminal Block. The indicator accuracy will be reduced depending on the mounting direction if only the Terminal Unit is replaced and the Lot No. and serial No. of the Terminal Block and Terminal Unit do not match. The Lot No. and serial No. of the Terminal Block and Terminal Unit can be found on the labels affixed to the products as shown below.
Remove the terminal block. The label is affixed to the top of the unit.
The label is affixed to the left side of the terminal block.
If the Lot No. and serial No. of the terminal block and Unit are the same, basic performance specifications apply regardless of the mounting direction. If the numbers are different, the following indication accuracies apply.
Mounting direction | Indication accuracies | |
---|---|---|
Mounted normally (1) | As specified in the Performance Specifications. | |
Mounted in any other
direction other than (1) |
(±0.3% of indication value or ±2°C, whichever is greater) ±1 digit max. | |
Input type | Indication accuracies | |
K1, K2, T, and N below -100°C | ±3°C ±1 digit max. | |
U, L1, and L2 | ±3°C ±1 digit max. | |
R and S below 200°C | ±4°C ±1 digit max. | |
B below 400°C | Not specified. | |
W | ±0.3% of indication value or ±4°C (whichever is larger)
±1 digit max. |
|
PLII | ±0.3% of indication value or ±3°C (whichever is larger)
±1 digit max. |
