Validity

This document applies to products with the following part

numbers:

PT R26 850

(DN 16 ISO-KF)

PT R26 851 (DN 16 CF-F)

The part number (No) can be taken from the product

nameplate.

If not indicated otherwise in the legends, the illustrations in

this document correspond to DN 16 ISO-KF vacuum con-

nection. They apply to other vacuum connections by analogy.

We reserve the right to make technical changes without prior

notice.

All dimensions are indicated in mm.

Intended Use

The Compact Pirani Capacitance Gauge PCR 260 has been

designed for vacuum measurement of gases in the pressure

range of 5×10

-4

… 1500 mbar.

It must not be used for measuring flammable or combustible

gases which react in air.

The gauge can be operated in connection with a Pfeiffer

Vacuum controller or with another evaluation unit.

Functional Principle

The PCR gauge is a combination gauge consisting of a Pirani

sensor and a capacitive diaphragm sensor. Both sensors are

constantly active.

At low pressures, only the signal of the Pirani sensor is used

for pressure measurement; at high pressures, only the signal

of the capacitive diaphragm sensor. To determine the output

signal in the intermediate range, both signals are used

proportional to the pressure.
