Motor monitoring relays

Motor monitoring relays now include phase monitoring, which uses microprocessor-based designs to protect against phase loss, reversal, unbalance, undervoltage and overvoltage conditions.


ProSense Motor Monitoring Relays

ProSense motor monitoring relays now include phase

monitoring, alternating and pump seal failure relays. The phase monitoring

relays use microprocessor-based designs to protect against phase loss,

reversal, unbalance, undervoltage and overvoltage conditions. With a variety of

user-adjustable settings, the relays also feature a multi-color LED to indicate

normal and fault conditions.

The PMRR series provides protection against phase reversal,

while the PMRRL series, with an adjustable undervoltage setting knob, protects

against phase loss, reversal and undervoltage. AR series alternating relays

feature a three-position selector switch to alternate two loads as normal, or

lock the relay to one load or the other. The ARX model is a DPDT cross-wired

unit that alternates two loads as normal, or locks the relay to always operate

the same load first each time.

Also available are PSFR series pump seal failure relays,

which monitor the shaft seals of submersible pumps. Featuring a user-adjustable

sensitivity knob, the relays are available in two 8-pin models - SPDT single

channel or dual channel relay with two SPNO contacts.

Accompanying 8-pin 10 A, 600 V octal sockets are also

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
