1. INTRODUCTION
The head-mounted versi on of the Te mperature Trans mi tter, Fr
Bl ock for RTD Pt-100 sensor i nput and Thermocoupl e i nput, converts a
te mperature sensor si gnal i nto a 4 to 20 mA DC current l oop po wered
si gnal wi th excel l ent l i neari ty and l oad dri vi ng capabili ty.
The Transmi tter i s mounted on the head of the temperature sensor
and accepts ei ther a three-wi re RTD Pt-100 sensor or a Thermocoupl e
sensor and converts i t i nto a li near current l oop si gnal of 4 to 20 mA DC,
capabl e of dri vi ng a l oad of up to 600 Oh ms. The i nstrument operates i n
two- wi re confi gurati on.
The Temperature Transmi tters are avai l abl e i n hi ghl y compa ct
executi ons and al l ow for cal i brati on of output to the requi red measured
te mperature range by means of e xternal setti ngs for Zero and Span.
