WIKA operating instructions thermowell, model TW61

1. General information

■The thermowells described in the operating instructions have been manufactured

using state-of-the-art technology. All components are subject to stringent quality and

environmental criteria during production. Our management systems are certified to

ISO 9001 and ISO 14001.

■These operating instructions contain important information on handling the thermowell.

Working safely requires that all safety instructions and work instructions are observed.

■Observe the relevant local accident prevention regulations and general safety

regulations for the thermowell's range of use.

■The operating instructions are part of the product and must be kept in the immediate

vicinity of the thermowell and readily accessible to skilled personnel at any time.

■Skilled personnel must have carefully read and understood the operating instructions

prior to beginning any work.

■The manufacturer's liability is void in the case of any damage caused by using the

product contrary to its intended use, non-compliance with these operating instructions,

assignment of insufficiently qualified skilled personnel or unauthorised modifications to

the thermowell.

■The general terms and conditions contained in the sales documentation shall apply.

■Subject to technical modifications.

2. Design and function

2.1 Description

The model TW61 thermowell is used to adapt thermometers and measuring inserts to the

process and protects the sensor against harsh process conditions. Furthermore, it enables

the removal of the temperature probe without having to open the process.

To integrate it into the process, the thermowell is directly orbitally welded into a pipeline.The

connection ends are smooth and prepared for orbital welding.

In combination with a resistance thermometer, the rotatable threaded connection of the

connection head or the display can be loosened and turned to the desired orientation.

The measuring insert can be withdrawn together with the connection head. In this way,

it is possible to calibrate the entire measuring chain (sensor, transmitter if applicable,

connection cable) on site, without having to disconnect the electrical connection. In addition

this avoids having to open the process, and thus the risk of contamination is minimised.

The thermowell is not piggable.

2) In the event of replacement, select a resistance thermometer measuring insert model TR11-A.

The corresponding sensor length, l5, is calculated as follows:

Insertion length U1 + neck tube length M (85 mm) + 5 mm pre-load + 10 mm head dimension

Pre-load

DIN 11866 row A or metric

3) Maximum operating temperature 150 °C

4) All thermowells of this series that are internally pressurised, with a nominal diameter (DN) > 25 mm, are

manufactured and tested to module H of the pressure equipment directive.
