Pfeiffer Vacuum PCR 280, Active Pirani/Capacitance Transmitter, DN 16 ISO KF, PT R26 855 / PTR26855 (Direct Replacement for PCR 260, PTR 26850)
Product Overview: Pfeiffer Vacuum PCR 280 Dual Pirani/Capacitance Transmitter:
(Direct Replacement for PCR 260, PTR26850)
The Pfeiffer Vacuum PCR 280 Compact Dual Pirani Capacitance Transmitter has been designed for vacuum measurement of gases within pressure range of 5 * 10^[-5] to 1500 mbar. It must not be used for measuring flammable or combustible gases in mixtures containing oxidants (e.g. atmospheric oxygen) within the explosion range.
The Pfeiffer PCR 280 is a dual-combination transmitter consisting of both a Pirani sensor and a diaphragm Capacitance sensor, all within a single measurement chamber. Both sensors are programmed to remain active during the measurement process.
At low pressures, only the signal of the Pirani sensor is utilized for pressure measurement; while at higher pressures, solely that of the diaphragm Capacitance sensor is utilized. To determine the output signal in the intermediate pressure range, both signals are used proportionally to respond to the pressure and establish a reading.
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.
