When controlling laser diode temperature, the LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the LFI3751 and the laser. This option also offers improved overshoot suppression, 50% faster settling times, and faster calibration. This option provides better set point resolution and stability with low-resolution sensors such as RTDs. Also, view Thermoelectric current and voltage and limit current settings.Ī Digital PID option is now available in the LFI3751 Digital temperature control instrument. The LFI3751 calculates the Steinhart-Hart coefficients and displays either actual temperature or sensor resistance. For example, to calibrate your thermistor, simply enter three data points from the Resistance vs. Sensor calibration is easy with a reference right on the front panel. Contact Tech Support for details if your application uses the Windows 64-bit OS and Benchlink front panel emulation control.) A workaround for Benchlink install is available. ( NOTE: The Benchlink Installer is not compatible with 64-bit operating systems. Benchlink software simulates the front panel control from your PC. Free LabVIEW drivers simplify computer control. It comes with Addressable RS232 and USB control is available with an adapter cable: WCB404.
Autoranging sensor bias currents keep your sensor voltage in the optimal range for maximum signal to noise ratio. With the touch of a button, the LFI3751 automatically optimises control settings for most thermal loads, reducing overshoot or improving temperature stability.
Autotune PID is a sophisticated algorithm for optimizing the PID control parameters to your load. The 4-digit display shows actual or setpoint temperature or resistance, output current and voltage. An external analog setpoint input is via BNC on the rear panel (Analog version only). Even across ambient, this PID controller maintains precision temperature.įrom the front panel, adjust temperature limits, current limits, setpoint, PID control values, sensor calibration data, and enable or disable output current. Expect stability as good as 0.001☌ with thermistors. This instrument operates from AC (100-240V, 50 or 60Hz). Drive up to ±5 A to either thermoelectrics (TECs) or resistive heaters (RH) with up to 8 V compliance. The high-performance LFI3751 with Autotune PID temperature control instrument is now CE-compliant.
