Introduction
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.
