A temperature transmitter converts the signal from a temperature probe—such as an RTD or thermocouple—into a two-wire 4-20mA output signal. In contrast, a temperature converter requires a separate power supply and is typically a three- or four-wire device.
The transmitter draws power from the 4-20mA loop itself, using less than 4mA. While converters can output either current or voltage, transmitters provide only a 4-20mA signal, making them a more efficient option for industrial control systems.
Datexel temperature transmitters accept input from thermocouples, RTDs, millivolt sources, resistances, and potentiometers. They play a critical role in accurate and reliable temperature measurement in demanding industrial environments.
Most of Datexel’s head-mounted models are temperature transmitters, including the popular DAT1010 and DAT1015. For voltage output applications, Datexel offers the DAT1135 Head Mount Temperature Converter, which provides a 0-10V output.
Datexel manufactures a full range of temperature transmitters, including head mount (hockey puck) types, DIN rail mount, and OEM board-level versions. Options include PC programmable, DIP switch configurable, isolated, and low-cost OEM designs.
