Temperature Transmitter- Series 651
4-20 mA signal. Two wire operation.Temperatures from -55° to +180°C.
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 BS 1904) or ungrounded Type K thermocouples. Thermocouple models 651TC are cold junction compensated, automatic 0 to 70°C with upscale burnout. These economical devices provide the accuracy and reliability you need at the lowest possible cost.
