Bulk cryogenic gas storage vessels and vacuum jacketed gas delivery lines are designed with a vacuum barrier that retards costly product loss. The vacuum level must be periodically verified using the thermocouple vacuum sensors that are ordinarily installed on the vessel or delivery line during manufacture.
The VD8TC vacuum tester by now enables the bulk gas supplier’s field service staff to quickly and easily measure the vacuum level even if the sensors being used are from different manufacturers or have different measuring ranges. The tester is compatible with the most popular thermocouple vacuum sensors. With the press of one button, it automatically detects which sensor brand and model is connected. Within a few seconds a stable vacuum measurement is displayed. If desired, this measurement can be stored in the instrument’s data logger by one more push of the same button.
For monitoring multiple sensors, Thyracont offers their ADiscs (pat. pend.). This device attaches to each thermocouple sensor and provides an individual electronic identification. A USB interface enables the user to evaluate and document measurements with Thyracont’s VacuGraph Windows software on a PC. After each measurement, the date, time, sensor ID and pressure value are stored.
The VD8TC completes the successful VD8 product family, which includes five other compact vacuum meters with data logger and USB interface. These are based upon piezo resistive, Pirani or hybrid sensor technologies.
