Summary

Product identification

Model: Omnigrad TA566
Type: Heavy duty - General purpose thermowell
Manufacturing: From hexagonal bar stock
Process connection: 1" NPT threaded

Description

The TA566 is an industry-standard thermowell manufactured from hexagonal bar stock with a threaded process connection. The stem can be straight or tapered for faster response times. Extension, immersion, and tapering lengths are customizable. A range of standard diameters and materials are available, with options for custom orders and different surface finishing grades.

Application

Designed for use with resistance and thermocouple thermometers, primarily in heavy-duty applications.

Order key structure

The order key for the TA566 includes selections for:

Extension Length T: Standard options (50, 75, 110 mm) or to specification.
Outside diameter Q1 / Taper diameter Q2 / Taper length R: Standard options available (e.g., 12.7mm (1/2")=Q1 / 12.7mm (1/2")=Q2 / 63.5mm (2 1/2")=R) or to specification (maximum Q1 of 28mm).
Immersion length U: Standard range (50-850mm) or special lengths to specification.
Material: Standard options include SS316Ti / 1.4571, SS316 / 1.4401, SS316L / 1.4404, or to specification.
Finishing of Immersion Length: Standard options of 0.8 micron or 1.6 micron.
Bore diameter F / Bottom thickness D: Standard options (6.5 mm=F / 6.35 mm=D or 13 mm=F / 6.35 mm=D) or to specification.
Plug and chain: Options include without, or with SS 304 plug and chain.
Markings: None or punched on.

Notes:

Bore diameter F = 13 mm is only for position (1) in the order key.
A minimum wall thickness of 3 mm is required, calculated as (Q2 - F) / 2 ≥ 3 mm.
