Installation .backup.book Page 26 Tuesday, January 10, 2012 11:57 AM 3 INSTALLATION OPTITEMP TRA/TCA PLUS 3.1 General notes on installation DANGER! For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation. CAUTION! Installation, assembly, start-up and maintenance may only be performed by appropriately trained personnel. The regional occupational health and safety directives must always be observed.
.backup.book Page 27 Tuesday, January 10, 2012 11:57 AM INSTALLATION 3 OPTITEMP TRA/TCA PLUS 3.4 Proper installation CAUTION! Take the following points into consideration prior to installing the thermometer: • The dimensions of the thermowell (length, diameter, wall thickness, type of tip) comply with the requirements of the measuring point. The mechanical load as a result of flowing media, vibration and resonances is the focus here. In addition, incorrect dimensions can lead to measurement errors.
.backup.book Page 28 Tuesday, January 10, 2012 11:57 AM 3 INSTALLATION OPTITEMP TRA/TCA PLUS To avoid measurement errors, ensure that the insertion length ("b" in the drawing below) meets the following requirements: • Insertion length = 10...15 x thermowell diameter, but at least 100 mm / 3.94" (shorter insertion lengths are possible but they impair measuring accuracy). • Tubes with Ø < 300 mm / 11.

Weld-in thermometers can be installed in two different ways: • Welded in directly: possible in pipes and tanks with a wall thickness ≥20 mm / 0.
.backup.book Page 35 Tuesday, January 10, 2012 11:57 AM INSTALLATION 3 OPTITEMP TRA/TCA PLUS 3.6.2 Threaded thermometer A threaded thermometer can be installed two different ways: • Screwed in directly: Pipes with a wall thickness ≥ 20 mm / 0.79" make it possible to drill a hole and cut a thread. • Screw into threaded sleeves: Pipes with a wall thickness < 20 mm / 0.79" require a sleeve to be welded in; these are not included in delivery but make up part of the accessories range.

Operation .backup.book Page 38 Tuesday, January 10, 2012 11:57 AM 5 OPERATION OPTITEMP TRA/TCA PLUS 5.1 Start-up CAUTION! Double check the following things prior to starting up an industrial thermometer in order to avoid measuring errors as well as damage to or the destruction of the thermometer: • Ensure that the thermowells have been properly installed according to the manufacturer's instructions. • Ensure that the process connection has been successfully tested for leaks.
.backup.book Page 39 Tuesday, January 10, 2012 11:57 AM OPERATION 5 OPTITEMP TRA/TCA PLUS Temperature indication too high or too low When reference measurements result in an incorrect temperature indication, three causes come into question: • Severe heat transfer caused by too short insertion length of thermowell or measuring insert: the thermometer indicates a temperature that is too low when it is above the ambient temperature and one that is too high when it is below the ambient temperature.

.backup.book Page 64 Tuesday, January 10, 2012 11:57 AM 7 TECHNICAL DATA OPTITEMP TRA/TCA PLUS 7.4 Measuring accuracy The measuring accuracy depends largely on the following factors: • The version of the measuring insert (type of sensor, type of circuit, measuring range). • The correct dimensions (diameter, wall thickness) and insertion length of the thermowell for good thermal coupling to the process temperature (insufficient insertion depth often results in measurement errors).

.backup.book Page 73 Tuesday, January 10, 2012 11:57 AM TECHNICAL DATA 7 OPTITEMP TRA/TCA PLUS 7.8 Sensor response times Thermometer response times are generally indicated as "50% time" (t05) and "90% time" (t09). "50% time" refers to the time needed for a thermometer signal to achieve 50% of its end value in the face of erratic temperature changes (this applies analogously to "90% time"). INFORMATION! You can find more information about response times in VDI 3522.
