Operating conditions
Load limits The load limits depend on several factors (e.g. dimensions, design
and material of thermowell). The compact sensor TRA-C10 can
handle pressure up to 16 bar / 232 psia while TRA-C20 and TRA-C30
can handle pressures up to 40 bar / 580 psia. This applies only if the
sensor is mounted properly.
Temperature Temperature Temperature Temperature
Process temperature Maximum -50...+200°C / -50...+392°F, depending on design and
material.
Pre-configured temperature
ranges
-50...+150°C / -58...+302°F or 0...+100°C / 32... +212°F
(Other ranges available on request)
Ambient temperature Maximum -40...+85°C / -40...+185°F, depending on media
temperature, sensor design and material.
Storage temperature -40...+70°C / -40...+158°F at 40...60% relative humidity.

Protection categories Following protection categories can be provided if the connection
cable is properly connected:
OPTITEMP TRA-C10, TRA-C30: IP67
OPTITEMP TRA-C20: IP65
Shock resistance: Acc. to IEC60068-2-31, test Ec
Vibrations resistance: Acc. to IEC60068-2-6, test Fc, 10-2000Hz, 4g
Installation conditions
Insertion angle 90° to the flow, directly against or diagonally against the flow.
Insertion length Recommendable: 10...15 x thermowell diameter for gas,
5...10 x thermowell diameter for liquids (short insertion lengths may
impair measuring accuracy).
Materials
Thermowells (including process
connection)
The metal materials of the thermowells, neck tubes, flanges and
threads as process connections are always identical:
Standard: Standard: Standard: Standard:
1.4404 / AISI 316 L (X2CrNiMo 17-12-2)
Process connections
Threaded thermometer Gastight thread acc. to ISO 228/1: G½, other sizes on request.
Attachment using welding sleeves. Starting at a wall thickness of
20 mm / 0.8", it is possible to screw in directly with thread in the pipe
Flange thermometer Acc. to ISO 2852: DN25/38, other sizes on request.
