Thermocouple Vacuum Gauges


DV-4 series, the sensor head structure is simple, compact, and so robust, which has been widely used in industrial applications. The cost performance is very higher than other vacuum gauges. It is also easy to install gauge system translates a thermoelectric voltage to a vacuum pressure based on the density of the gas. The thermocouple gauge tube/sensor is fully compensated for temperature and rate of temperature change, as an AC heating voltage will be generated in using an internal transformer.




Range: 0.1 Torr - 20 Torr

NIST Reference Tube


The gauges are calibrated for nitrogen or air, but conversion factors for other gases are available from the factory. The thermocouple gauge or controller does not require recalibration when thermocouple gauge tubes are replaced further decreasing process down time. However, our NIST traceable reference tube DB-16D is available to confirm meter/controller performance.

The Hastings History

 

In 1968, Hastings-Raydist (Teledyne-Hastings Instruments) was selected to provide the sensor to measure the vacuum in the moon rock box that was to accompany Apollo 11 on the first moon landing. The box, with the Hastings vacuum sensor installed, was sterilized and sealed under vacuum prior to lift off. It was opened on the moon, rock samples were put in the box and it was sealed again under moon vacuum. It was returned to earth and the vacuum was checked with the Hastings vacuum sensor, the seal had not been compromised.
