Description

The P60R8 pH sensor is a dependable
industrial grade sensor designed to
provide accurate measurement and longer
service life under the most demanding
conditions. Some features of this sensor
include: differential measurement
technology, replaceable salt bridge and
encapsulated preamp.

The P60R8 incorporates all the benefits
of differential measurement found in other
models of the 60 series, field proven in
thousands of installations. This technique
uses two glass electrodes to make the
measurement differentially with respect to
a third metal electrode. The domed glass
process electrode is specially designed for
tough applications. The second electrode
is immersed in a pH 7 buffer encapsulated
in the sensor.

This second electrode is protected
from the process by a double junction
replaceable salt bridge. The resulting
true differential measurement has several
advantages over conventional sensors:
ground loop problems are virtually
eliminated, and the salt bridge is easily
replaced.

If the internal solution becomes
contaminated, the sensor can be
rejuvenated at modest cost by replacing
the salt bridge and reference solution.
Automatic temperature compensation is
accomplished through the use of a Pt1000
RTD at the tip of the sensor. This Pt1000
RTD placement provides rapid response
for process temperature variations.

The encapsulated preamplifier provides
an output signal which can be transmitted
3000 feet over inexpensive cable. Another
version encapsulates a blind 4-20 mA two
wire transmitter which can transmit a
virtually unlimited distance over a twisted
pair cable. (See P65 data sheet).
