Description

The TX12 is a low cost head mounted pt100 4-20 mA transmitter that accepts RTD temperature sensors and converts sensor output over a selected range into a 4 to 20 mA transmission signal. The transmitter is a two-wire, loop-powered device, and is fully configurable by the user, over a wide temperature range, with the aid of a simple push button. This new TX12 design incorporates additional configuration menus, allowing the user to push button trim the transmitter output at both zero and span, ideal for trimming out sensor errors. The transmitter's advanced circuitry ensures high stability over the wide operating ambient temperature ranges experienced by head mounted devices. One of the transmitter's features is the program LED, which provides visual indication of sensor fault when in normal operation and is also used to guide the operator through the simple menus during configuration.

Supplied as standard with scaling of 4mA at 0°C and 20mA at 100°C
