New Pfeiffer Vacuum PBR 260, Active Pirani & Bayard Alpert Hot Cathode Vacuum Gauge, DN 40 ISO KF, PT R27 001 / PTR27001

New Pfeiffer Vacuum PBR 260, Active Pirani & Bayard Alpert Hot Cathode Vacuum Gauge, DN 40 ISO KF, PT R24 001 / PTR27001

Product Overview - Pfeiffer PBR 260 Active Pirani & Bayard Alpert Gauge (w/DN 40 ISO-KF, 40 Millimeter Flange):

The Pfeiffer Vacuum PBR 260 Active Full Range Gauge has been designed for vacuum measurement of non-flammable gases and gas mixtures. It must not be used for measuring flammable or combustible gases in mixtures containing oxidants (e.g. atmospheric oxygen) within the explosion range.

The PBR 260 Gauge is part of the Pfeiffer Vacuum Compact Gauges family and can be operated in connection with the MaxiGauge™ measurement and control unit TPG 256 A or with another evaluation unit. Over the entirety of its measurement range, the Compact FullRange™ BA Gauge has a continuous characteristic curve, whilt the measuring signal is displayed in the format of output as a logarithm of the pressure.

The PBR 260 Gauge functions with a Bayard Alpert Hot Cathode ionization and a Pirani measurement system. In a defined overlapping pressure range, a mixed signal of the two measurement systems constitutes as output. Above the pressure threshold, solely a Pirani signal is displayed. Below the pressure threshold, the hot cathode signal becomes the sole indicator of output. The Pirani signal switches the hot cathode measurement system on and off to prevent filament burn-out and excessive contamination. The user can select among two settings/thresholds for the switch process.

This unit is NEW and comes with a Guaranteed 6-Month Warranty.

A Brief Overview of Pressure Measurement Within a Vacuum System:

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area - the Pascal (Pa) is the SI unit commonly used to measure pressure, equivalent to one newton per square meter. Alternatively, pounds per square inch (psi) can also be used as a unit of pressure measurement. In determining the degree of pressure within a vacuum or system, most gauges measure pressure relative to atmospheric pressure, a level referred to as the zero point. Vacuum gauges are especially precise instruments, as they are able to detect the slightest deviations from a state of total vacuum. Any reading greater than total vacuum in such a state constitutes a form of pressure, and thus a vacuum gauge uses total vacuum as the zero point. A vacuum gauge utilizes an absolute scale, whereby the lever begins at the zero point (a complete absence of pressure within a state of total vacuum) and can only change in one direction (as pressure increases).

Differential pressure is likewise an important concept in the field of pressure measurement, as it conveys the difference in pressure between two points or systems. Often times, this refers to the difference between standard atmospheric pressure (typically about 100 kPa at sea level) and the pressure within a vacuum environment. Differential pressure analyses are commonly used in industrial processing systems, and are incorporated within many of the products sold and serviced by A&J Vacuum Services. Differential pressure gauges feature two inlet ports, each connected to one of the two environments where pressure is to be monitored. By monitoring the pressure differential between a near-vacuum environment and one featuring standard atmospheric pressure, the user/operator may obtain an accurate pressure reading by subtracting the difference in total pressure between the two systems.
