Series 659 Push-Button Temperature Transmitters
accept thermocouple (J, K, T), RTD (Pt100Ω) or thermistor input and
provide a linearized 4 to 20 mA output. The transmitter is quickly
ranged and calibrated by using a single on-board switch. An LED provides
visual indication of sensor fault and programming mode. Models feature
reverse polarity protection. Thermocouple models are also galvanically
isolated and cold junction compensated.
The compact transmitter can be mounted directly within any standard
thermal head for connection to the sensor. The Series 659 Transmitters
are ideal for temperature measurement in boilers, burners, ducts,
furnaces, refrigeration systems, food processing, tanks, chemical
processing, steam generators or any other process application.
