Manhole covers from China to France to New York have been disappearing - stolen and
sold for scrap. There are hundreds of thousands of manholes in New York City, weighing
in at over 300 pounds each. One NYC thief thoughtfully puts up orange safety cones
around the open manholes, but according to one expert crooks overseas often replace
stolen covers with flimsy substitutes: 'they put a piece of styrofoam over the hole,
like that's going to help'.
New SST3 Provides Cost Effective Electronic Control
The brand new SST-3 brings precise electronic control to a wide variety of applications.
With a set point that is adjustable from 34 degrees to 150 degrees it's perfect
for freeze protection, grease lines, hot water maintenance, and light process applications.
The set point is easily configured via the front panel. The temperature sensor
can be mounted up to 2,000 away from the control unit. The digital display provides
real-time pipe temperature, as well as easy to understand error codes. A low temperature
alarm is activated if the pipe remains 4 degrees below the set point for 30 seconds
or longer. Built-in alarm relays allow interface with building management systems. The
SST-3 provides ground fault protection without the need for expensive GFEPD breakers
utilizing a built-in 30 mA GFEP that is digitally filtered to minimize false tripping.
The GFEP self-tests every 24 hours. For critical fire protection systems the
SST-3 can be set with GFEP as alarm only, without de-energizing the heater cable,
so trouble-shooting can take place without compromising safety. This precise
controller energizes heaters when the pipe temperature goes below the set point,
and turns them off when the temperature rises 2 degrees F above the set point, saving
energy and money. The temperature sensor can be mounted up to 2,000 feet away from
