When mounting your end device, care should be taken to make sure it is as far away from any metal objects. If nearby metal gets too close to your unit, it has the potential to interfere with the way the unit radiates and may cause signal lose or possibly even the inability to communicate at all with your receiver.

5.2.2 Installation

When installing your End Device it is important to position your device in such a way as to optimize the antenna location within what’s known as the “Fresnel

Zone”.

The Fresnel Zone can be thought of as a football-shaped invisible tunnel between two locations that provides a path for RF signals between your End Device and your receiver.

END DEVICE

RECEIVER

ANTENNA

FRESNEL ZONE

Figure 17. Fresnel Zone

In order to achieve maximum range, the football-shaped path in which radio waves travel must be free of all obstructions. Obstacles in the path (especially metal) will decrease the communication range between your End Device and receiver. Also, If the antennas are mounted just barely off the ground, over half of the Fresnel zone ends up being obstructed by the earth resulting in significant reduction in range. To avoid this problem, the antennas should be mounted high enough off of the ground so that the earth does not interfere with the central diameter of the Fresnel zone.

NOTE:

It is important to understand that the environment may change over time due to new equipment or machinery being installed, building construction, etc. If new obstacles exist between your End Device and receiver, the devices can be raised on one end or on both ends to hopefully clear the

Fresnel Zone of obstructions.

NOTE:

No co-location with other radio transmitters is allowed. By definition, co-location is when another radio device or the device’s antenna is located within 20 cm of your connector/transmitter and can transmit simultaneously with your unit.

NOTE:

Never install multiple End Devices within 20 cm or less from each other.

NOTE:

Never use your UWTC End Device as a portable device. Your unit has been designed to be operated in a permanent installation only.

5.2.3 Antenna Connection

Your End Device has been shipped to you with a standard approved antenna.

NOTE:

Use of any other antenna then what’s supplied with your End

Device will void all FCC, IC and CE regulatory compliance.

5.3.3 Antenna Connection

Your receiver has been shipped to you a high gain antenna already attached.

In some cases, a short RF cable may be used to connect an antenna to your end device. Please note that RF extension cables will always add some loss to the transmitting signal strength. The longer the cable the more signal will be lost over that cable. Because of this the length of the cable should be kept as short as possible.

NOTE:

Use of any other antenna then what’s supplied with your End

Device will void all FCC, IC and CE regulatory compliance.

Section 6 - System Operation

6.1 Introduction

Compared to wired systems, a wireless system provides 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 wireless system.

6.2 RF Communication Basics

The Model UWRH-2-NEMA sends wireless transmissions to a 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

A basic wireless thermocouple system is comprised of only two main components; a signal conditioner with a built-in battery powered 2.4 GHz radio transmitter, and a USB powered 2.4 GHz radio receiver.

6.5 Transmit Rate vs. Battery Life

Many factors such as ambient temperature conditions and transmitting rate can have a big effect on the life of the battery used in your end device. Transmitting data places a big demand of the battery in your unit. The transmit rate is the single most contributing factor in the life of your battery. The slower the transmit rate you set, the longer the battery in your device will last. The table below give some estimates on how long the battery should last vs. the transmit rate you selected when you setup your end device and under normal operating conditions.
