1-3 CONSIDERATIONS General El ectrical temperatu re sensors suc h as RTDs and thermocoup les produce low -level signals proportion al to their sensed temperature. The Models 244 EH and 244E R transmit ters convert the low-level s ensor signal t o a standard 4–20 mA d c signal that is relat ively inse nsitive t o lead lengt h and electrical noise.
