摘要: 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.

摘要: A pressure transmitter with a fluid isolator that includes a sensor tube and a fill tube that have “D” shaped ends that connect together in a port internal to the transmitter. The shaped ends can be brazed into the port for sealing. Fitting both the sensor tube and the fill tube in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator has an isolator diaphragm with a central diaphragm region overlying a central backing plate that includes a annular groove. The annular groove avoids slow response of the isolator after an overpressure condition.
