The TX401 and TX402 head mount temperature transmitters transform a temperature signal acquired from a Pt100, Pt1000 (TX401 only) or Ni100 RTD sensor or from a thermocouple (TX402 only) into a linearized 2-wire loop-powered 4 to 20 mA output. The characteristics of these converters ensure high precision on the reading scale with 16-bit conversion. The 4 to 20 mA output can be scaled based on the desired temperature input range.
The programming procedure uses an RFID (NFC) mode with the dedicated TX400-RFID programmer that allows the user to make all calibrations and settings quickly and without the need to power and connect up the transmitter. Simply connect the TX400-RFID programmer to the USB port of your PC, start the RF Programmer configuration software and place the transmitter on top of the TX400-RFID programmer to establish communications.
An additional programming tool is the Omega Brand Google App - "Direct Link" relying on RFID/NFC connectivity and allowing straightforward programming without wirings by Android devices.
These temperature transmitters are also provided with a data logging function for the input signal. Transmitters have a non-volatile memory (circular buffer) for data-logging with user-selectable sampling time. The user selects the sampling time (1 to 3600 seconds) and then each time the 4 to 20 mA loop powers the device, the input value is stored to nonvolatile memory.
Using the TX400-RFID programmer along with the RF Programmer configuration software (software is a free download from OMEGA) the user can:
• Completely configure the transmitter including scaling the 4 to 20 mA output to desired temperature input range
• Implement field calibration to compensate for gain and offset errors
• Download logged data to PC for visualization and printing

Does this product include cold junction compensation?
Thank you for your inquiry. Model TX401 only accepts RTD inputs. Model TX402 accepts both RTD and thermocouple inputs and has built in cold junction compensation.

In the specifications there is a link to the Play Store Android app for Omega’s “Direct Link” software that allows you to configure the TX40x with your smartphone. The link is broken and the app cannot be found in the store. Is there a replacement?
Hi JMach,
Sorry to hear of the difficulty. Please forward this question to TEMP@DWYEROMEGA.COM.
Best regards

What is the maximum allowable load resistance in the 4-20 mA loop? Is there a formula for computing this maximum resistance?
It would be dependent on your supply Voltage but here are the equations to calculate - MAX impedance of input where you connect transmitter 0-20 mA depends on supply voltage,
Formula is:
Zmax =((VCC – VCCmin) / 0.021)
VCC = supply voltage for the transmitter
VCC min = 8 VOLT (MINIMUM operating voltage of transmitter 6V + 2V safety margin)
0.021 = max Ampere value obtainable from transmitter for anomaly notice
At operating voltage 24V_VCC >> Zmax = approx 750ohm
