Disclosed example pressure transducers include: an absolute pressure sensor comprising a fluid input and a sensor housing configured to contain a reference pressure, and configured to output a signal representative of a pressure sensed at the fluid input; an outer insulation housing around the sensor housing of the absolute pressure sensor, wherein a volume between the outer insulation housing and the sensor housing comprises a vacuum pressure, wherein the outer insulation housing has a pinch tube configured to allow establishing of the vacuum pressure in the volume when the outer insulation housing is assembled to form the volume, and to seal the vacuum pressure in the volume when the pinch tube is sealed.

Absolute pressure transducers having improved operating temperature ranges

A compact valve block for a chemical container wherein the coaxial valve block has a housing that can accommodate three valve control mechanisms thus allowing for quick and effective purging without the need for an additional external conduit, valves, and coaxial injector. The advantage is a greatly reduced amount of wetted surface area inside the valve block leading to a significant decrease in the time it takes to purge a system thus allowing for quicker times to change chemical containers.
