Measuring Instruments & Equipment

We are leaders in the market for providing best range of Thermowell

Thermowell

A Thermowell is a protective enclosure for Temperature Gauges and Temperature Sensors ( Inserts), which enhance the life of the Inserts from the corrosive and abrasive( harsh) service conditions at the installation point without affecting the performance of the Temperature Sensors or Gauges. A Thermowell allows the temperature sensor to be removed and replaced without compromising either the ambient region or the process.

We at Goa Instruments, strive to provide Thermowells, which suit the Process Parameters like Pressure, Temperature, Density, Viscosity, and Velocity in accordance with International PTC Standards.

Three Major Types of Thermowells.Using Bar

Bar Stock Flanged
Bar Stock Threaded
Bar Stock Weld In

Using Pipe & Bar

Fabricated Flanged
Fabricated Threaded
Fabricated Weld In

Bar Stock Thermowells are offered for Insertion Lengths up to 600mm as a Standard.

Insertion Lengths can also be provided up to 900mm in Bar Stock if required.

Fabricated Thermowells are generally preferred for Insertion Lengths above 600mm.

We have a IN HOUSE Wake Frequency Calculator , in accordance with ASME PTC 19.3 TW-2010 for determining the Insertion Length and the Type of Construction best suited for the Process Parameters as required by the Client.

Our extensive internal database, on material selection, for the Thermowells , assist us in recommending and suggesting a suitable MOC for the product which will bring out the Optimum performance of the Thermowells under the process parameters and different types of Process Fluids.

We also offer Thermowells with Sleeves, Coatings and Linings customized to suit the Clients requirements.

Thermowells with more than one material as MOC can also be offered for minimizing cost and improving the efficiency, response and longetivity of the Thermowell under harsh and corrosive conditions.
