Series 651 Temperature Transmitter

Brand: Dwyer Instruments, LLC

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.

Linearized output for precise temperature monitoring or control is combined with small size and quick, easy mounting.

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.
