Lunt Pressure Tuner Controller with USB connection

Name: Lunt Pressure Tuner Controller with USB connection
Brand: LUNT Solar
SKU: PCUSB
Price: 1234 EUR

The USB Pressure Tuner Controller provides precise, microprocessor-controlled operation of the Lunt Pressure Tuner System - also via remote control.

No interfering vibrations, since the Pressure Tuner no longer needs to be touched

Digital control of the tuning mechanism for a constant central wavelength and finer adjustments

USB interface for seamless integration into computer systems, allowing precise electronic adjustment - even remotely -

Manual control is also possible; the optimal value can be saved.

Includes a 3m air-pipe for convenient remote connection between the controller and the telescope´s pressure tuner

The device is powered by a rechargeable battery with a runtime of more than 12 hours; however, to ensure a reliable power supply, it can also be powered by an AC adapter (included).

Lunt Solar Systems Pressure Tuner Controller with USB connection

The Lunt Solar Systems Pressure Tuner Controller, or PC-USB, is a microprocessor controlled, remote operable* , pressure control system that can be retrofitted to any Lunt PT product without return to the Lunt facility. A simple 1/8" airline connects the PC-USB to the Solar Telescope and can be installed at any length.

The PC-USB is a simple 2 button system. One button for increasing and one button for decreasing the PT pressure. Both buttons are used together to save the setting. Digital feedback and indicator lights are provided. The device can also be controlled remotely via USB.

The PC-USB can run continuously on internal battery power for more than 12 hours. It has external power input (12 to 15 V DC, for example 120/240 V AC to 12 V adapter) that can power the unit and charge the internal batteries simultaneously.

All existing PT systems can be retrofitted via an adapter to the pressure tuner knob. Or, future PT units can be specified with a quick disconnect at the PT input, removing the PT knob from the telescope altogether.

Upon power up the PC-USB will go through a systems vent and ambient pressure set mode. It can be factory or user programmed to center wavelength setpoint. Due to the sealed nature of the system, the center wavelength setpoint will remain constant at any altitude at a given set pressure point.

The Pressure Tuner Controller is accurate to 0.3 PSI (0.0207 bar, 20.7 hPa), providing very precise control of the pressure setpoint. It will auto-compensate for fluctuations in internal pressure changes due to significant changes in temperature. Because the PC-USB can provide closed-loop feedback of internal etalon pressure, users can correlate change in pressure to doppler shifted events.

Normally, the telescope vibrates while you are adjusting the focus mechanically. This is especially true at high magnifications, such as when observing the Doppler effect on a filament. With the PC-USB system, there is absolutely no telescope vibration during focusing at any magnification, making it easier to observe events with Doppler shifts.

* USB cables for remote usage are not included; the device has a USB 2.0 Type-B port.
