TX402 Head Mount Temp Transmitter w RFID Communications 12905

 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
• TX401 Accepts Pt100, Pt1000 or Ni100 RTD Inputs
• TX402 Accepts Pt100 or Ni100 RTD Inputs and Types J/K/T/E/R/S/B/N Thermocouples
• User Configurable via TX400-RFID (NFC) Programmer and Configuration Software
• High Accuracy
