Description:
The Differential pH Sensor
uses the field proven, three-electrode differential
measurement technique; the pH and reference electrodes are compared
to a ground electrode for excellent measurement accuracy, even
in harsh chemical applications. The sensor body is offered in
glass-reinforced Ryton for chemical compatibility in most process
solutions. The replaceable salt bridge and refillable reference
reservoir insures a long service life in applications containing
sulfides (H2S) and metals such as lead, mercury, and silver.
It will maintain a constant reference cell potential by resisting
dilution over time with pressure and temperature changes. The
patented porous Teflon® reference junction resists fouling
and chemical attack. The sensor cable has a built-in preamplifier
to boost the pH signal while ensuring a quiet and reliable measurement.
The transmitter powers the preamplifier. A self-powered preamplifier
is also available as an option for use with analyzers which
do not have an adequate voltage source. The capillary temperature
sensor design places the temperature element within the pH sensitive
membrane for fast and accurate temperature measurement and compensation.
The 1-inch NPT versatile body allows mounting into a standard
1-inch pipe tee or onto the end of a pipe for immersion into
a vessel. Mounting adapters are available in CPVC or 316 SS
for direct replacement of GLI sensors used in 1-½ inch
threaded pipe tees. Other materials are available upon request.
