Engineering Specifications
Ryton Sensor
PEEK Sensor
D
1. The pH or ORP sensor shall be of Differential Electrode Technique design using two
D
electrodes to compare the process value to a stable internal reference standard buffer solution.
The standard electrode shall have non-flowing and fouling-resistant characteristics.
1. The pH or ORP sensor shall be of Differential Electrode Technique design
using two electrodes to compare the process value to a stable internal
reference standard buffer solution. The standard electrode shall have
non-flowing and fouling-resistant characteristics.
2. The sensor shall have a hex shaped body to facilitate mounting, and shall
be constructed of PEEK material for exceptional chemical resistance and
mechanical strength. This material shall enable the sensor to be installed in
metal fittings without leakage usually caused by heating and cooling cycles
when dissimilar materials are threaded together.
3. The sensor shall have a:
C
a) Convertible body style featuring 1-inch NPT threads on both ends to mount
into a standard 1-inch pipe tee, into a GLI adapter pipe for union mounting
with a standard 1-1/2 inch tee, or onto the end of a pipe for immersion into a vessel.
b) Insertion body style featuring 1-inch NPT threads only on the cable end to mount
into a GLI ball valve hardware assembly, enabling the sensor to be inserted into or
retracted from the process without stopping the process flow.
c) Sanitary body style featuring an integral 2-inch flange to mount into a GLI 2-inch
sanitary tee. The sanitary body style sensor shall include a special cap and EDPM
compound gasket for use with GLI sanitary hardware.
4. The built-in electronics of the sensor shall be completely encapsulated for protection
from moisture and humidity.

6. The sensor signal shall have an integral temperature sensor to automatically compensate
measured values for changes in process temperature.
7. The sensor shall include a titanium ground electrode (standard) to eliminate ground
loop currents in the measuring electrodes.
8. The sensor shall be Hach Company GLI Model PD1R1 for pH measurement or GLI Model
RD1R5 for ORP measurement.
