Summary
Product identification
- Product: Omnigrad TA550
- Type: Heavy duty - General purpose thermowell
- Construction: From round bar stock
- Standard Reference: ME U 819.02 - type 2
Description
The TA550 is an industrial standard thermowell manufactured from drilled round bar stock with a diameter of Ø 30 mm. It is designed for use with resistance and thermocouple thermometers, particularly in heavy-duty applications. The process connection can be threaded or flanged weld, and the stem can be straight or conical. Various extension and immersion lengths, bar dimensions, materials, and surface finishes are available.
