Section 6 - System Operation

6.1 Introduction

Compared to wired thermocouple systems, wireless thermocouple systems
provide much simpler installation. Based on the physical principle of the
propagation of radio waves, certain basic conditions should be observed. The
following simple recommendations are provided to insure proper installation
and correct operation of your MWTC Series system.

6.2 RF Communication Basics

The Model MWTC wireless Thermocouple Connector/Transmitter sends
wireless transmissions to the MWTC-REC1, MWTC-REC5, or MWTC-REC6
receiver. The receiver checks the incoming data for accuracy and processes
this data for use by the measurement software on your PC. Radio signals are
electromagnetic waves, hence the signal becomes weaker the further it travels.
While radio waves can penetrate some solid materials like a wall, they are
dampened more than when a direct line-of-sight between the transmitting and
receiving antenna exist.

6.3 Basic System Overview

The MWTC wireless thermocouple system is comprised of only two main
components; a Thermocouple Connector with a built-in battery powered radio
transmitter, and a USB powered radio receiver.
