Chemically-resistant LCP Body.
The exceptional chemical
resistance and mechanical
strength of the LCP (liquid crystal
polymer) sensor body makes it
ideal for most applications. These
sensors can be used in
aggressive process
solutions such as acids, bases,
alcohols, hydrocarbons,
aromatics, chlorinated
hydrocarbons, esters, ketones,
and most other chemicals.
Low Heat Distortion.
LCP sensors are physically stable
and will not expand or contract
when subjected to the heating and
cooling cycles of a process.
Furthermore, these sensors may
be installed in metal fittings
without fear of leakage, normally
a problem when dissimilar
materials are threaded together

Excellent, Strong Base
Chemical Compatibility.
The Ryton sensor is best suited
for measuring strong base
solutions of more than 12 pH at
elevated temperatures. It can also
be used in acidic solutions, but is
not recommended when aromatic
hydrocarbons are present.

These multifunction Model 535 1/4 DIN Single Loop Process Controllers provide PID control of any analog process variable (temperature, pressure, level and flow) in batch and continuous process applications.
Available models of the 535 Process Controllers provide a proportional analog control signal output that is typically used to regulate a control valve or similar final control element. Also available, are process controller models with alarm trip outputs for on/off control or to warn of unwanted high/low conditions, and with RS-485 communications for interface with digital-communicating DCS, PLC, and PC-based SCADA systems.
When ordered with the Profile Controller option, the 535 Process Controllers provide full ramp and soak capability with 20 recipes and 24 segments per recipe; guaranteed soak with adjustable hysteresis; three event output capability; and a ramp that can be programmed to take place over a specific amount of time or to be based on PV rate of change per hour.
535 Process Controllers offer advanced tuning features which allow you to bring the process under control faster, more accurately and far more easily than competitive single-loop controller, PLC and PC-based strategies. Its autotune capability constantly analyzes your process and makes modifications to the tuning parameters to ensure precise, long-term, stable control.

Operative Limits: 0 to 50°C (32 to 122°F).
Storage Limits: –40 to 70°C (–40 to 158°F).
10 to 90%, non-condensing.
Two univeral process variable inputs are standard.
Available options include: remote setpoint, slidewire feedback
and 5 digital inputs.
Four outputs are available. See Ordering Information.
RS-485 Communications: Available as option with any
configuration.
Isolated serial communications is available using an RS-485
interface. Baud rates of up to 19,600 are selectable. The
protocol supports CRC data checking. If communications are
lost, a time-out feature will command the controller to a particular
control mode and specific setpoint or output if desired.
Outputs 2-4 and digital inputs can act as “host-controlled” I/O
independent of the controller’s function. The PV may besourced via this interface. May be installed in the field.
Universal power supply: 90 to 250Vac, 48 to 62Hz. 24V
(AC or DC power optional).
Common mode rejection (process input): >120 dB.
Normal mode rejection (process input): >80 dB.
AC line is double filtered and transient protected. Snubbers are
provided for each relay output.
Inputs and outputs are grouped into the following blocks:
Block 1: process variable
Block 2: outputs 1, 2, and 4
Block 3: communications, set of five digital
inputs, output 3 (Earth Ground)
Block 4: remote setpoint
Each block is electrically isolated from the other blocks to
withstand a HIPOT potential of 500Vac for 1 minute or 600Vac
for 1 second, with the exception of blocks 1 and 4, which are
isolated to withstand a HIPOT potential of 50 volts peak
for 1 minute between each other. Inputs and outputs are not
isolated from other inputs and outputs within the same block.
