May 2017
LIQ-PDS-PERpH-X
A sensor design that is flexible to meet your demanding pH/ORP application needs
Rosemount 3500 PERpH-X sensors are versatile sensors suited to meet a number of difficult application requirements. These high
performance sensors are ideal for use in high temperature and high pressure processes and feature a wide array of options to solve
your pH/ORP measurement needs.
Rosemount PERpH-X Sensors
Overview
May 2017
Expanded Application Flexibility
Selectable reference electrolytes allow sensors to be used in a
large number of applications.
Electrolyte options include:
• High Temperature – most suitable for use in highly acidic, basic or
oxidative solutions, and high temperature applications.
• Bio-Film Resistant – inhibits the growth of bacteria and algae
• Poisoning Resistant – most suitable for use in processes containing
sulfides, mercaptans, and cyanides
• Oil Resistant – aimed for use in applications where light oils and
greases can foul a sensor
• Scaling Resistant – targets applications where the precipitation of
calcium magnesium salts like gypsum or water hardness coat over
the electrode
• Metal Resistant – most suitable for use in applications where
chloride in the reference electrolyte would react with the process
Minimize Maintenance and Lower Total Cost of
Ownership
A long lasting rebuildable reference junction and electrolyte
extends sensor life and allows sensors to be easily rebuilt
where normally other sensors would have to be replaced.
SMART preamplifier allows automatic recognition of pH
sensors by Rosemount transmitters: 1066, 1057, 1056,
and 56.
pH calibration data is stored which allows sensors to be
calibrated in advance for “Plug and Play” installations in the
field.
Versatile Mounting Options to Meet Your
Installation Requirements
Ryton body sensors feature 1 in. MNPT front and rear facing
process threads.
Titanium body sensors offered in 21 in. and 36 in. lengths
suitable for use with retraction assemblies.
Variopol (VP8) cable connection option, for quick
cable-to-sensor release, eliminates cable twisting.

Rosemount 3500P pH/ORP Sensor
Ordering Information
Rosemount PERpH-X High Performance pH/ORP Sensors feature various sensor body
options. Sensors are available in a chemically resistant Ryton plastic body
(3500P/3500VP) or titanium tube housing (3300HT/3300HTVP/3400HT/3400HTVP).
Rosemount 3500P/3500VP sensors are constructed with front and rear facing 1 in.
MNPT threads for insertion or submersion type installations. Rosemount
3300HT/3300HTVP/3400HT/3400HTVP) sensors must be used with a process
connector allowing for various insertion depths. These titanium body sensors also have
extended sensor length options allowing installation through a ball valve assembly.
Sensors feature a Teflon reference junction and a Pt-100 RTD for temperature
compensation. Rosemount PERpH-X pH/ORP sensors are available with either an
integral cable connection or Variopol (VP8) connector. Variopol cables sold separately.
