These products are designed for processes where the customer wishes to measure and control the process over a very wide pressure range. Standard single一range Baratrons can be used in pressure control systems down to at least 0.1%of their full-scale range, but at pressures below 0.05% of full-scale, the analog output of the manometer is low enough that some pressure controllers may not be able to resolve the signal correctly. The dual一range Baratrons solve that problem by adding a second output signal that is 2X, 5X, or 10X higher in gain than the primary range, which increases the analog output signal by that same amount. These Baratrons are heated to either 450C or 1000C, are available with or without internally-mounted process relays, and have a single 15-pin D-subminiature electrical connector. Primary pressure ranges from 10 to 1000 Torr （13 to 1333 mbar） are available, and the secondary pressure range is 2X, 5X, or 10X less than the primary range.
