Linearized output for precise temperature monitoring or control is combined with small size and quick, easy mounting. Rugged Series 651 Transmitters are designed for use with 2 or 3-wire Pt100 RTDs (to DIN standard 43760 or BS1904) or ungrounded Type K thermocouples. Thermocouple Models 651TC are cold junction compensated, automatic 32°F - 160°F (0°C - 70°C) with upscale burnout. These economical devices provide the accuracy and reliability you need at the lowest possible cost.

• Various preset ranges available
• Pt100 or K type thermocouple models
