CryoCon temperature sensors

CryoCon manufactures a range of temperature sensor controllers and resistance bridges, which are also used for temperature sensing. There is some overlap between different products, but they still use fairly distinct interfaces and interaction patterns. The code has been tested with CryoCon 14C temperature controller.

The main device class is pylablib.devices.Cryocon.Cryocon1x.

Software requirements

The device provides a bare RS232 interface, so any appropriate USB-to-RS232 adapter should work.

Connection

Since the devices are identified as COM ports, they use the standard connection method, and all you need to know is their COM-port address (e.g., COM5):

>> from pylablib.devices import Cryocon
>> sensor = Cryocon.Cryocon1x("COM5")
>> sensor.close()

Operation

The operation of this temperature sensor is fairly straightforward, but there is a couple of points to keep in mind:

  • Like most similar devices, querying temperature using Cryocon1x.get_temperature() immediately returns the most recently measured value. Re-measurement is periodically initiated by the devices itself.
