Description

The P60C-8 pH and the R60C-8
ORP probe are dependable indus­trial grade sensors designed to pro­vide accurate measurement and
longer service life under the most
demanding conditions. Some fea­tures of these probes include: dif­ferential measurement technology,
replaceable salt bridge and encap­sulated preamp.

The P/R60C-8 incorporates all the
benets of differential measure­ment found in other models of the
60 series, eld 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 probe.

This second electrode is protected
from the process by a double junc-

tion replaceable salt bridge. The re­sulting true differential measurement
has several advantages over con­ventional probes: ground loop prob­lems are virtually eliminated, and the
salt bridge is easily replaced.

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

The encapsulated preamplier 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 P/R65 data
sheet).
