TA temperature transmitters installation guidelines

For the best performance of the TA family of sensors, please adhere to the guidelines on this page.

Should you need additional support, feel free to contact our service center at 888-704-0702 and speak to one of our applications engineers.

There are five variants for the sanitary TA family as shown in the table below.

	Description	Process connectors
TA22xx	Ø6 mm stick probe, 50…350 mm insertion length	Required. Use E30144 compression fitting and one of the process connectors below.
TA25xx	Ø6 mm probe, 30…150 mm insertion length, G ½” sanitary sealing cone	Required. Use E43911 PEEK sealing ring and either a clamp fitting or welding fitting.
TA20xx	Ø6 mm probe, 25…60 mm insertion length, integrated ¾” triclamp	N/A – ¾” triclamp connection is integrated.
TA28xx	Ø6 mm probe, 30…150 mm insertion length, integrated 1.5” triclamp	N/A – 1.5” triclamp connection is integrated.
TA11xx	Ø3 mm probe, 17…83 mm insertion length, M12 sealing cone	Required. Use E43915 PEEK sealing ring and a weldable fitting.
TA13xx	Ø3 mm probe, 17…83 mm insertion length, G 3/8” internal thread	Required. Use a thermowell of appropriate length.

Sensor orientation

For best cleanability, do not install the sensor at the lowest point of the pipe or tank as shown by position 5 in the image. This allows the medium to run off the probe and avoid building up over time.

Leakage ports, or weep holes, in process fittings, are required for installations in accordance with 3A guidelines. When an o-ring is place, the process medium remains in the tank or pipe. If that o-ring is compromised, i.e. missing or damaged, the medium will leak at the weep hole. This is an indication that the o-ring must be replaced.

Be sure to install the fitting such that the weep hole points downward.

To avoid dead space, adhere to the dimensions shown and ensure L < (D – d).
