ifm TA2105 Temperature Transmitter, -50 to 150 C, IO-Link

ifm TA2105 Temperature Transmitter, -50 to 150 C, IO-Link

The ifm TA2105 is a compact temperature transmitter: a Pt1000 element and evaluation electronics in one stainless steel housing, with a 4 to 20 mA analogue output and IO-Link. The measuring range is -50 to 150 degrees Celsius, the process connection is a G 1/4 external thread, and the probe is 6 mm in diameter with a 25 mm installation length. Precision of the analogue output is ±0.3 K plus ±0.1 % of the measured span.

The transmitter reacts quickly (T05/T09 of 1 and 3 seconds) and has a very short power-on delay. Seven Star LLC supplies the TA2105 in Oman and the GCC as an independent supplier.

TA2105 technical specifications

The table lists the values published by the manufacturer for the TA2105. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the TA2105 works

The TA2105 combines a Pt1000 element with transmitter electronics in one stainless steel housing. The element sits in a 6 mm probe tip for fast response, while the electronics linearise the resistance curve and produce either a 4 to 20 mA analogue output or IO-Link digital data. Because the evaluation is built in, the device delivers a temperature value directly to the controller, with a stated precision and a very short power-on delay.

Where the TA2105 fits and related parts

The TA2105 delivers a finished signal, unlike the TM4511 which needs an evaluation unit. It fits PLC analogue inputs or IO-Link masters directly. Choose it for compact installations on machines and skids with a G 1/4 port.

Selection and ordering checklist for the TA2105

Work through the points below before you confirm the order, so that the TA2105 you receive is the one your machine or plant needs.

• Confirm the range -50 to 150 degrees Celsius
• Choose output: 4 to 20 mA or IO-Link (configurable)
• Check supply 18 to 32 V DC and the loop load
• Check the G 1/4 port and seal
• Use a four-pole M12 cordset

The manufacturer lists this article under the type designation Temperature transmitter, TA-025CLER14-A-ZVG/US. The article number TA2105 is the reference to quote when ordering, and the type designation is useful for technicians who compare the label on an installed unit.

Installation, commissioning and maintenance

Screw the transmitter into the pipe or vessel using the G 1/4 thread and a suitable sealing ring, tighten within the stated torque, and ensure that the probe tip reaches into the flow rather than sitting in a dead leg. Connect it with a four-pole M12 cordset and set the measuring range if you do not want the factory setting. During commissioning compare the reading with a reference thermometer. Over its life, inspect the sealing ring and the connector, and leave a short length of cable slack so vibration does not load the plug.

Tighten to 35 Nm, with a seal ring in good condition, and make sure the probe tip is in the flow. Commission by comparing with a reference thermometer and setting the range if the factory setting of -50 to 150 degrees Celsius is not suitable. The housing is IP67, IP68 and IP69K, so cleaning with high pressure is not a problem, but protect the cable from strain.

Typical applications in Oman and the GCC

Cooling water, hydraulic oil and lubricating oil temperature on machines, compressed-air aftercoolers, chiller loops, and process lines. In the GCC the extended range to 150 degrees Celsius covers hot oil circuits and utilities.

Temperature sensors in utilities and cooling loops see wide swings between night and afternoon. Good thermal contact with the medium and a sealed connector are what keep the readings stable over years of service.
