THS Series Sanitary Thermistor Sensors
The PRS series sensors are manufactured
with 316L stainless steel wetted surfaces
that have surface finishes of 32 microinch
or better. Care should be exercised when
handling the sensors so that the surface finish
is not damaged during handling or
installation.
GENERAL DESCRIPTION
The Omega PRS series sensors are designed
for use in Sanitary Clean-In-Place (CIP)
systems. They are supplied standard with
1-1/2" 16AMP Style flanges so they can be
assembled to like style piping connections.
Other connection sizes and styles are
available.
WIRING CONFIGURATION:
The Omega THS Style sensors are supplied
with 2-wire connections as shown below.
The sensor wiring is connected to the two
inner screws of the terminal board leaving
the outer screw terminals for the instrument
connection. Please note that thermistor
sensors have no polarity.
These sensors are supplied with thermistor
elements that provide a non-linear resistance
temperature output that has significantly
greater resolution (in ohms per degree) than
do our RTD sensors. Please note that
thermistor sensors require lower operating
currents than do RTD sensors, typically
around 12 microamps max, in order to
insure that no self-heating occurs.
Resistance vs. Temperature Tables and
Equations for each thermistor offered are
provided on page 2.
OPERATING CURRENT:
As is the case with most precision thermistor
sensors, Omega THS series sensors should
be powered with no more than 12
microamps of excitation current. If operated
at higher currents, self heating errors may
occur.
PROCESS CONNECTION:
This sensor includes a mounting flange that
connects to a similar flange located at the
process connection point. A commercially
available gasket is used between the sensor
flange and the process flange, with a clamp
used to compress the two together.
SPECIFICATIONS:
Sensing Element Type: Thermistor
Accuracy: ±0.2°C between 0 and 70°C.
Temperature Range: -80 to 150°C (-112 to
302°F).
Excitation Current: 12 microamps max.
Response Time: 2.5 seconds max (63%)
Wetted Surfaces: 316L Stainless Steel with
32 microinch or better surface finish.
Connection Head: White Polypropylene
with 3/4" NPT Cable Connection (NB9W
Style).
