These analog temperature transmitters are ideally suited for power engineering, plant construction, ventilation, heating, refrigeration, air-conditioning and other related applications. They are designed for thermocouples or pt1000/pt100 with a 10 v output coupled with a (T91.10) 3-wire and 2-wire mechanism (T91.20). These devices deliver superior precision, conciseness, low price ratio and feature a failure indicator for sensor depletion.
