LFI3751 Digital Temperature Control Instrument wPID Autotune

Lfi3751 Digital Temperature Control Instrument Wpid Autotune

Wavelength Electronics, Inc. >>

Description

The LFI3751 with Autotune PID is a high performance temperature control instrument. Drive up to ±5 A to either thermoelectrics (TECs) or resistive heaters (RH) with up to 8 V compliance.
Expect stability as good as 0.001°C with thermistors. From the front panel, adjust temperature and current limits, setpoint, PID control values, sensor calibration data, and enable/disable output current. The 4-digit display shows actual or setpoint temperature or resistance, output current and voltage. Autotune PID is a sophisticated algorithm for optimizing the PID control parameters for most thermal loads, reducing overshoot or improving temperature stability. Autoranging sensor bias currents keep sensor voltage in the optimal range to maximize signal to noise ratio. The LFI3751 Digital provides better setpoint resolution and stability with low resolution sensors such as RTDs, as well as offers improved overshoot suppression, 50% faster settling times, and faster calibration.
