Product Overview

2.1

Introduction

The TracXP Wireless TXP-WTA Sensor Transmitter is available with 900 MHz or 2.4GHz frequency to meet your

communication requirements. The TXP-WTA Sensor Transmitter can be configured in single or dual sensor

configurations to allow redundant readings for critical operations or monitoring combination gases. The TXP-WTA

Sensor Transmitter’s smart sensors allow users to easily change sensor types. The TXP-WTA Sensor Transmitter also

supports integral and remote sensor options. Intuitive non-intrusive magnetic interface makes set up and

programming quick and easy. Power options include standard 3.6V disposable Lithium battery for portability or a 12-

24V DC power option for longer term or permanent installations.
