Electromagnetic Transmitters General Information - SPY PIG TRACKING SYSTEMS Operating Instructions Manual

Electromagne tic
Transmit ters general
information
SPY Inspection Equipment transmitters pulse at approximately one
®
pulse every second, which helps to identify this signal over spurious
random noise that the receiver may pick up. This pulse can easily be
detected by using our pig tracker receiver (PTR) and by many other
electromagnetic receivers on the market.
The PT-101 and PT-107 are designed to be mounted in a Poly foam
cavity pig. The PT-275 and PT-750 can be placed in a cavity pig,
mounted to a mandrel pig, or towed behind another pig for ease of use.
These transmitters are "O" ring sealed (water tight) and capable of
working in high-pressure environments (see page 7). Their main bodies
are constructed of rugged carbon steel. Care should be exercised
when exposing them to harsh chemicals. Check with the factory for
chemical compatibility.
Our electromagnetic transmitters utilize off the shelf batteries for easy
inexpensive replacement capability. While these batteries provide
ample life for the transmitters in service, it is prudent practice to use
fresh batteries prior to each new use. Please note that you should
check the expiration date on the batteries that you purchase as older
batteries with reduced life might be sold at retail outlets.
