Pixsys 2000.35.031 Converter / Convertitore TC-RTD > 4..20mA
User manual - Manuale d'uso
Introduction / Introduzione
Thanks for choosing a Pixsys device. The Signal converter code 2000.35.031 converts a signal obtained from temperature sensors PT100, PT1000 or NI100 (with a 2, 3 or 4 wires connection) into a current signal for 4..20mA loop (2 wires).
Main features:
- High accuracy;
- 16bit conversion;
- Programmable by RFid (NFC);
- Input -10..+70 mV
- 2624 Word non-volatile memory (circular buffer) for data-logging with sampling time selectable by the user;
- Possibility to rescale the output 4..20mA compared to temperature input value;
- Field calibration to compensate eventual errors (Gain and Offset);
- Compact dimensions;
The software RF Programmer (available for download on Pixsys website) and the RF Programmer allow:
- Complete configurability of the device;
- Download on PC of logged data;
- Visualization/printing of the temperature - time trend

Configuration / Configurazione
To configure this signal converter, it is necessary to use a RF Programmer and the configuration software RFID_Programmer, available on the download area of www.pixsys.net. After connecting the RF Programmer via USB and activating the software, it is possible in "EDIT" mode to configure the device selecting the type of sensor, measuring range, output for error signal, and sampling frequency for the registration. The keys "WRITE" and "READ" allow to write and read data on the devices quickly and easily.
On the lower side of the display, a list of all programmed devices is shown; it can be printed to confirm that the programming has been completed successfully.
(The original document includes screenshots of the software interface and programming options.)
Input options:
- PT100: Measuring range: -200..+600°C (2, 3, 4 wires)
- Ni100: Measuring range: -60..+180°C (2, 3, 4 wires)
- TC K: Measuring range: -260..+1360°C
- TC S: Measuring range: -40..+1760°C
- TC R: Measuring range: -40..+1760°C
- TC J: Measuring range: -200..+1200°C
- TC T: Measuring range: -260..+400°C
- TC N: Measuring range: -260..+1280°C
- TC B: Measuring range: +40..+1820°C
- TC E: Measuring range: -260..+940°C
- Input mV: Measuring range: -10..+70mV
Data Logger
This signal converter is provided with a datalogging function for the input signal. By setting the sampling time (selectable between 1 and 3600 seconds), each time the 4..20mA loop powers the device up, it will store the input value into a non-volatile memory. Through the RF Programmer, it is possible to download, display, or print all data.
