INTRODUCTION

ndumart SEM104 Series 2-Wire Temperature

Transmitters provide accurate and reproducible

conversion of RTD or thermocouple signals to 4-

20 mA output.

One model is designed to accept RTD (Pt-100,2

or 3 wire) input. The others accept types J, K and

T thermocouple inputs and also provide automatic

thermocouple cold junction compensation.

The transmitters will be supplied in standard

factory calibrated ranges, but on board links allow

the transmitter to be easily re-ranged to operate

over most industrial and commercial applications.

ZERO and SPAN potentiometers are provided to

allow fine re-calibration at both ends of the scale.

The SEM104 Series are mounted on the standard

33 mm fixing centers of miniature RTD or

thermocouple connection heads.
