ABSTRACT:
An improved pressure transducer is disclosed. The transducer includes a connector, an enclosure, a sensor portion, and an external heater disposed to heat the sensor portion. In some aspects, the sensor portion includes a sensor constructed from a brittle material and does not employ any fill fluid within the sensor. In another aspect, the invention includes a kit that adapts non-heated high purity vacuum transducers for heated use. The kit includes a connector portion and a heater portion that is coupled to the connector portion. The connector portion may also include one or more indicators.
