Rosemount 65Q
Introduction
September 2014
Rosemount Series 65Q Temperature Sensor is designed for use
in hygienic and aseptic applications exclusively to meet the
stringent quality requirements in the Food and Beverage, and
Pharmaceutical industries. Rosemount temperature products
are manufactured according to Good Manufacturing Practice
(GMP) guidelines and comply with the standards of the
European Hygienic Equipment Design Group (EHEDG) as well as
3A standards.
National and international guidelines
Products that may have a direct or indirect impact on public
health, must be produced according to national and
international guidelines. The guidelines contain rules for the
implementation and organization of methods, production,
production environments, and inspections.
The European Hygienic Equipment Design Group (EHEDG) is a
foundation in which mainly users and manufacturers or hygienic
equipment are represented. EHEDG provides guidance of the
hygienic engineering aspects of manufacturing of safe and
wholesome food, e.g. through production, publication, and
updating of guidelines, equipment approval through
certification to assist equipment suppliers and food
manufacturers and advisory function to legislators and
standards groups.
EHEDG cooperation with 3-A
EHEDG cooperates with 3-A Sanitary Standards, Inc. in the
development of hygienic construction material selection and
design standards for food and dairy processing equipment. 3-A
Sanitary Standards and Practices have been developed for use by
the dairy industry, dairy equipment manufacturers, and milk
regulatory agencies as voluntary guidelines. These voluntary
guidelines are used as a benchmark for product performance,
hygienic quality, and ultimately food safety. 3-A Sanitary
Standards and Practices are generally accepted by federal, state,
and local public health authorities in the United States and other
public health authorities around the world.
While 3-A Sanitary Standards have been in development and use
since the late 1920’s. EHEDG is a fairly recent development that
applies test criteria and laboratory test data for determining
cleanability and acceptance for equipment use in the processing
of foods or comestibles. Both EHEDG and 3-A Sanitary Standards
may be applied not only to Food and Beverage processing
equipment, but can also be applied to Biotech and Bio-pharm
equipment to ensure product acceptance and safety.
Mounting configurations
The Rosemount 65Q can be ordered with flying leads or terminal
block. Ordered with flying leads, the sensors are designed with
an integral mounting plate, and are for use with a head-mount
transmitter attached directly to the sensor. The flying lead
configuration facilitates removal of the sensor and transmitter
as one assembly. The configuration with terminal block allows
only the mounting of transmitter into the cover of several DIN
size connection heads or requires the use of field mount
transmitter.
Series 65Q RTD – sanitary applications
Rosemount Series 65Q Integral Mount Temperature Sensors are
designed for use in hygienic, food and beverage applications
when fitted with the Tri-Clamp, adjustable Weld-in Ball or
Tapered Union with Coupling Nut according to DIN 11851 (Dairy
Connection) process connections which do not need to meet as
harsh aseptic requirements as requested for BioPharm
applications. Alternatively for direct insertion into non-hygienic
processes, the Series 65Q Temperature Sensor can be ordered
optional with G½-in. (½-in. BSPF) or ½-in. NPT thread mounting.
The 65Q is available alone or as complete assemblies including
connection heads, thermowells with weld-on process
connections. This offering is designed to be used in complete
temperature assemblies including Rosemount Temperature
Transmitters. The RTD sensors meet most critical parameters of
international standards - DIN EN 60751 incorporating
Amendments 1 and 2. All sensors are available in a variety of
lengths and ranges with terminal block or flying leads.

Material selection
Emerson provides a variety of Rosemount product with various
product options and configurations including materials of
construction that can be expected to perform well in a wide
range of applications. The Rosemount product information
presented is intended as a guide for the purchaser to make an
appropriate selection for the application. It is the purchaser’s
sole responsibility to make a careful analysis of all process
parameters (such as all chemical components, temperature,
pressure, flow rate, abrasives, contaminants, etc.), when
specifying product, materials, options and components for the
particular application. Emerson Process Management is not in a
position to evaluate or guarantee the compatibility of the
process fluid or other process parameters with the product,
options, configuration or materials of construction selected.

Identification data
The model and serial numbers are marked on each sensor.
Ingress Protection (IP) ratings
The particular rating is applicable only for complete assemblies
including a connection head and tubular thermowell. IP varies
from 65 to 68 due to a wide selection on different connection
heads, DIN A and B size, made of different materials such as
aluminum, polyamide, and stainless steel.
System components
Sensor
The 65Q sensor consists of an exchangeable mineral-insulated
measuring insert, wherein a small, drop-form thin film RTD
element is encapsulated. This design protects the relatively
strain-free element, thereby maintaining accuracy and
long-term stability. The sensor is mounted into a swaged or
straight stainless steel sheath. The sensor outer diameter is 3.2
mm. The minimum sensor length for an exchangeable sensor is
100 mm. The RTD sensor is fitted into a housing with connection
head and welded thermowell.
Extension
Standard material Stainless Steel 1.4404 (316 L)
Standard diameter of 10 mm
Preferred standard lengths; 50, 65, and 130 mm
Connection heads (see Tab l e 2 )
The connection heads can be of different types (size DIN A and
B) and materials (plastic, aluminum, stainless steel). Its fitting to
the rest of the probe and the gland for the cable entry, assure an
IP grade of 65 at minimum. All supplied heads have a process
connection M24x1.5.

Mounting style and process connection
Achieving absolute control through every step of the
manufacturing process is essential in order for the production of
sanitary fittings to be successful. By achieving such control, each
fitting will perform more satisfactorily when incorporated into
the process installation, reducing installation time, and ensuring
process integrity.
Process connections are available in several sizes
Process connection is continuously welded on the thermowell
in such a way to obtain a welding radius of 3.2 mm at
minimum, between the lower surface of the connection and
the sensor stem according to 3A standards

Installation
Series 65Q Temperature Sensors can be mounted on the wall of
pipes or vessels. The counterparts for the process connections
and the respective gaskets or sealing rings are generally not
supplied with the sensors, and are on the customer's
responsibility (FDA material certification, EHEDG and 3A
requirements shall be observed).
As a general rule, the sensors should be installed in a manner
which does not adversely affect their ability to be cleaned.
The immersion length may have an influence on the accuracy of
the sensors, If it is too short, an error might be generated in the
measured temperature, due to the lower temperatures of the
process medium near the walls and the heat transfer which
occurs through the sensor stem. To avoid this effect of
inaccuracy, the immersion length should be, if possible, at least
90 to 120 mm. In pipes with smaller diameter, the axis line of the
duct must be reached, and even slightly exceeded by the sensor
tip.

Rosemount 65Q
In hygienic applications a strict installation rule exists so as not
to leave any dead spaces along the run of process fluid.
In case of disassembling of the sensor, new gaskets equal to the
originals and specific torques must be employed for the
reassembly procedure, to assure the stated IP grade of the
connection heads.
TriClamp Flange partially fulfills this requirement.
For Weld-in Ball Connection, care should be taken by the user
in the execution of the welding on the process side; e.g. suitable
weld material, welding radius > 3 mm, absence of pits, crevices
etc.)
Tapered Union with Coupling nut according to DIN 11581
(Dairy Process Connection) process connection doesn't meet
as harsh aseptic requirements as requested for BioPharm
applications.
Alternatively, for direct insertion into non-hygienic processes,
the Series 65Q Temperature Sensor can be ordered with
optional G

/2-in. (1/2-in. BSPF) or NPT thread mounting.
