MKS Instruments 974B Vacuum Pressure Transducer¶
- class pymeasure.instruments.mksinst.mks974b.MKS974B(adapter, name='MKS 974B vacuum pressure transducer', address=253, **kwargs)¶
Bases:
MKSInstrument
MKS 974B vacuum pressure transducer
Connection to the device is made through an RS232/RS485 serial connection.
The 974B pressure transducer is a pressure gauge combining a cold cathode ionization current measurement, a Pirani sensor, and a Piezo sensor to cover a large pressure range. It optionally includes up to three mechanical relays which can be energized based on the measured pressure value.
- Parameters:
adapter – pyvisa resource name of the instrument or adapter instance
name (string) – The name of the instrument.
address – device address included in every message to the instrument (default=253)
kwargs – Any valid key-word argument for
