gland in hygienic design
Description
The model TR22-A resistance thermometer is used for
temperature measurement in sanitary applications. The
process connections meet the stringent requirements, in
terms of materials and design, of hygienic measuring points.
With increased hygienic requirements for the ambient
areas around the measuring point, a stainless steel head is
available in an optimised hygienic design. This enables easy
cleaning of the measuring instrument, particularly for splash
zones in food production.
Due to the rotatable screw connection to the connection
head, it is possible to loosen the connection head and to
adjust it in the desired position. The connection head can be
removed together with the measuring insert. This allows the
resistance thermometer to be calibrated along with the whole
measuring chain, i.e. without disconnecting the electrical
connections. In addition, this avoids having to open the
process, and thus the risk of contamination is minimised.
The spring-loaded measuring insert guarantees the contact
between the sensor tip and the bottom of the thermowell and
thus ensures a fast response time and high accuracy.
The welded junction between the thermowell and the flange
makes the use of a sealing as additional material in those
areas redundant which are in contact with the product.

1) Through their small design, face-sensitive measuring resistors serve to reduce the heat dissipation with short insertion lengths.
Available for the temperature range -50 … +150 °C (-58 ... +302 °F) in classes A and B.
For thermowell insertion lengths of less than 11 mm, face-sensitive measuring resistors are generally used.
2) For detailed specifications for Pt100 sensors, see Technical information IN 00.17 at www.wika.com.
3) The connection head should therefore be protected from temperatures over 80 °C (176 °F).
4) For the TR22-A design without thermowell, the insertion length is defined by the dimension A(l1) from the lower edge of the connection head to the tip of the measuring insert (see
“Dimensions of the connection heads in mm”). The thickness of bottom of the thermowell can be neglected for dimensioning. It is offset by the spring travel of the measuring insert.

WIKA data sheet TE 60.22 ∙ 01/2015
Options
The transition from the connection head to the thermowell is
effected via an optional sealing combination (polyurethane)
of flat gasket and wiper. This combination permanently
prevents the penetration and depositing of humidity and
impurities in this area (IP 68). Additionally, the sealing
combination simplifies the cleaning process significantly.
In combination with the patented BVS head and the cable
gland in hygienic design, it delivers an easy-to-clean and
hygienic measuring point, even in those areas not in contact
with the product. The BVS head is designed in such a way
that cleaning agents can run off easily and that no residues
can accumulate on the case.

Connection head with digital indicator
(option)
As an alternative to the standard connection head the
thermometer can optionally be fitted with an DIH10 digital
indicator. The connection head used for this is similar to the
model BSZ-H head. For operation, a 4 ... 20 mA transmitter
is needed, which is mounted to the measuring insert. The
indication range is configured identically to the measuring
range of the transmitter.

For the electrical connections of built-in temperature transmitters see the corresponding data sheets or operating instructions.
Explosion protection (option)
Resistance thermometers of the TR22-A series are available
with an EC-type examination certificate for “intrinsically safe”,
Ex i, ignition protection.
These instruments comply with the requirements of 94/9/EC
(ATEX) directive for gases and dusts.
The classification/suitability of the instrument (permissible
power Pmax as well as the permissible ambient temperature)
for the respective category can be seen on the EC-type
examination certificate and in the operating instructions.
Built-in transmitters have their own EC-type examination
certificate. The permissible ambient temperature ranges of
the built-in transmitters can be taken from the corresponding
transmitter approval. The system operator is responsible for
using suitable thermowells.
