| Abstract | An improved pressure transducer (50, 70, 80) is disclosed. The transducer (50, 70, 80) includes a connector, an enclosure, a sensor portion (58), and an external heater (32, 76) disposed to heat the sensor portion (58). In some aspects, the sensor portion (58) 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 (30, 52, 72, 82) that adapts non-heated high purity vacuum transducers (10) for heated use. The kit (30, 52, 72, 82) includes a connector portion (36, 84) and a heater portion (32, 76) that is coupled to the connector portion (36, 84). The connector portion (36, 84) may also include one or more indicators (58). |
