JETSEAL, Inc.
Seal against an I.D. and O.D. of the cavity JETSEAL is a world leader in designing and manufacturing Axial C-Seals. Unlike face seals, the axial seal is specifically designed to seal against an I.D. and O.D. of the cavity. Axial Seals are ideally suited to accommodate limited rotational or linear movements such as those found in liquid or gas valves. Since Axial Seals are metallic, they are ideal for use in cryogenics, superheated steam or high pressure viscous liquids. Sizes can range from .250 " up to 6.5 " diameter. Operating...

United Electric Controls Company
Case Study: Progressive Cavity Pump Protection Solution: The NOC chose the ONE Series SIL 2 Safety Transmitter with Safety Relay Output (SRO) because it combined the 4-20 mA output that went to the VFD with an integral safety relay that could directly shut down the PC pump. With the analog signal connected to the VFD and the embedded logic solver and relay providing redundant safety shutdown of the PC pump, the external power supply, relay and added enclosure were eliminated. An additional digital signal could be inputted to the VFD to alert... (read more)Browse Pressure Transmitters Datasheets for United Electric Controls Company -

Gurley Precision Instruments
Absolute and Incremental Rotary Encoders There are two basic types of rotary encoders: absolute and incremental. Absolute rotary encoders provide a coded angle information and avoid time consuming reference measurements or calculation routines in the controller. Incremental rotary encoders provide a square wave or sinusoid output signal and enable counters and PLC to calculate position, speed and distance. Rotary encoders come in four mechanical configurations: modular (kit-type), shaft, blind hollow-shaft and true hollow-shaft...
