XT/XTi transmitters are a type of transmitter for bypass level indicators. The measuring principle and construction of this series are identical to those of the XM series, however the XT series is equipped with a 2-wire transmitter module that converts the resistance into a 4-20mA output signal. An option with linearization of the tank content graph is available. There are two versions available: XT - Standard version and XTi - Intrinsically safe version.
The document describes the Barksdale XT and XTi series of transmitters designed for use with bypass level indicators. These devices convert resistance from a sensor into a standard 4...20 mA output signal. The XT version is a standard transmitter, while the XTi version is intrinsically safe (EEx ia IIC) for hazardous areas.
| Output signal | 4...20 mA, reversed polarity protected |
|---|---|
| Load resistance (XTi) | max. 700 Ohm at 24 V |
| Delay time | 0.33 sec |
| Accuracy | max. +0.2% f. s. |
| Temperature range (XT) | -40 °C... +85 °C |
The XT is a standard version, while the XTi is an intrinsically safe module with ATEX approval EEx ia IIC 11...16.
They are designed for use with bypass level indicators.
The maximum load is 700 Ohm at 24 V.
The accuracy is a maximum of +0.2% f. s.
