HF11 – 2 Wire RTD Simulator for PT1000

許風十一號

Hui Gardens HF11 2 wire RTD simulator for PT1000 was made to be used as a calibration standard for the Hui Gardens HF3 WiFi RTD Meat Smoker Temperature Transmitter. Coarse (10kΩ) and fine (1kΩ) adjustment via 10 turn potentiometers allow precise setting of resistance value. Since there are no graduated steppings like a traditional decade box, it does not require calibration and is as accurate as the multimeter being used to characterize it.

The banana plug connectors are spaced such that the fancy two conductor leads can be used. Connect the two sets of banana plug connectors to use them together or disconnect to use separately.

HF1 – 100W Resistor Box

許風一號

Hui Gardens HF1 100W resistor box prototype was created to provide a dummy load when testing electronics. It features an aluminum enclosure that also acts as a heat sink. Banana jack connector inputs were chosen for durability during transport and also to maintain a low profile. Just toss this rugged resistance standard into your Pelican case.

Due to the experimental nature of this decade box, each resistor is connected to its own banana jack connectors via blade connectors for easy replacement of individual resistors should they burn out.
