ECD pH S88 hazardous location sensors

AMS Instrumentation and Calibration introduces the S88 pH sensors from
ECD, featuring stainless steel housings.

Part of the Model S88 intelligent sensors line from ECD, the S88 offering
includes pH sensors, ORP sensors, ion selective sensors, dissolved oxygen
sensors, conductivity sensors and resistivity sensors. The S88 sensors have two
universal sensor designs – insertion/submersion and valve retractable with a flared
end to prevent blowout. The S88 sensors feature 316 stainless steel housings as
standard; however, the housings are also available in various materials to
maximise sensor performance while minimising cost of ownership.

The S88 pH sensors convert analogue signals from the electrode
cartridge into a digital protocol that allows two-way communication with the
transmitter. The identity of sensor, measurement type and serial
number are stored in the sensor’s memory along with three calibration
registers. When connected to an ECD digital analyser, the sensor’s information
is uploaded to the analyser, helping configure the displays and outputs of
the transmitter to the values appropriate to the sensor’s measured parameter.

The S88 insertion sensor uses a ¬æ” MNPT compression fitting as the
process connection. This allows a variable insertion length to accommodate
installation in pipe tees, flow cells, or through tank walls. Reversing the
fitting will allow the sensor to be installed in a stand pipe for submersion
into a tank.

The S88 valve retractable sensor uses a 1″ ball valve with a 1″ NPT
process connection. When the rear compression fitting is loosened, the sensor will
slide freely through the ball valve, stopping at the compression fitting for
either insertion into or retraction from the process.
