Series 651 Temperature Transmitter
RTD or Thermocouple Input, Zero and Span Adjust, Linearized 4-20 mA Signal
Linearized output for precise temperature monitoring or control is combined with small size and quick, easy mounting. Rugged Dwyer 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 to 160°F (0 to 70°C) with upscale burnout. These economical devices provide the accuracy and reliability you need at the lowest possible cost.
