Temperature plays a very important role in industrial processes. Every process is designed for particular temperature range. Out of the specified temperature range , can make the output defective. Which will increase the losses in the system.
There are multiple types of temperature sensors are available. Such as “Thermocouple “and “RTD “(resistance temperature detector). Some process requires precise temperature such as Pasteurizers while some of the machines do not require precision such as moulding machines.
RTD are much more accurate than Thermocouples. That’s why RTD are used in high precision machines. In this post, We are going to discuss RTD based one of the temperature transmitter that is “IFM TA2232“.
This temperature transmitter works on PT-1000 mechanism. This transmitter contains a microcontroller which produces temperature proportion analogous output and IO-Link. That’s why this sensor is known as “Temperature transmitter“.

IFM TA2232 Temperature transmitter
IFM TA2232 is a type of temperature transmitter. This sensor is a combination of “RTD” and “microcontroller“. The RTD PT-1000 continuously monitors the temperature and produces in proportion resistance variation While microcontroller converts the temperature data into analogous output and I-O Link.

Working of IFM TA2232
This temperature transmitter contains PT-1000 Type RTD. PT-1000 RTD produces linear variation in resistance in parallel with rise in temperature. At 0°C is produces 1000 ohm resistance . As temperature increases; resistance increases proportionally.
| Temperature | Resistance value of RTD PT-1000 |
| 0°C | 1000 ohm |
| 100°C | 1385 ohm Approx. |
Since this transmitter further contains controller which produces proportional analogous output current. Analogous milli amps current ranges from 4mA to 20mA.
| Temperature | Analogous output current |
| 0°C | 4mA |
| 100°C | 12mA |
| 200°C | 20mA |
Further a PLC system, reflects the temperature of the system as per according to scaling programmed in PLC. Temperature appears in proportion to mA analogous current output.
