Space-saving Dual Output Signal Conditioners

Mini-MW Series

RTD TRANSMITTER

Functions & Features

• Accepts direct input from an RTD

• Linearization

• Burnout

• “Active bridge” circuit containing two constant current

sources allows large leadwire resistances up to 200 Ω

• Fast response type available

Typical Applications

• Long distance transmission between the RTD and the

transmitter

• Combination with intrinsic safety barriers

MODEL: W2RS–[1][2][3]-[4][5]

ORDERING INFORMATION

• Code number: W2RS-[1][2][3]-[4][5]

Specify a code from below for each [1] through [5].

(e.g. W2RS-4A6-M2/BL/CE/Q)

• Temperature range (e.g. 0 – 500°C)

• Special output ranges (For codes Z & 0)

• Specify the specification for option code /Q

(e.g. /C01/V01)

For the input code C, specify also the following. If not

specified, Cu 10 Ω @25°C (usable range -200 – +260°C) will

be used.

• Input type (e.g. Cu 10 Ω)

• Resistance range (e.g. 9.038 – 12.891 Ω)

Note: If one of the outputs should be a current range,

specify it for the Output 1 to allow a greater load.
