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.

Figure 6-1. Basic System Overview

Up to 48 connector/transmitters can be used with MWTC-REC1, MWTC-REC5,

or MWTC-REC6 receivers.
