Encoder Mounting Configuations

Illustrating the various method of correct Incremental Magnetic and Absolute Encoder Mounting Configurations.

In all cases refer to relevant installation instruction and correct fit-up tolerances. The use of anti-backlash coupling for shaft to shaft coupling is advised.

Encoders are applied to measure speed and position in a wide variety of applications and are therefor available with numerous mounting styles. The mounting style should be selected carefully to best fit the application at hand.

VersaCount by Veeder-Root

The NEW Veeder Root VersaCount 1/16 DIN size multifunction counter is the most versatile counter on the market today. Whatever your application, timing, counting, rate measuring, position indicating, volume measurement, speed monitoring, length cutting or batch, shift, pulse or piece counting, the VersaCount is the only device you need when versatility counts.

Versatility doesn’t stop with functionality. The highest count frequency in the industry enables the VersaCount to perform in applications not previously possible with an electronic counter.  What would speed be without accuracy? That’s why the VersaCount features an unprecedented prescaler accuracy to one ten thousandth. Further, automation and precision control are achieved using three presets with relay hold times programmable up to ten minutes.

Veeder Root is the first in the industry to offer a programming assistant where applications can easily be created, archived and printed using the proprietary Programming Assistant software. VersaCount XP models allow the user to easily upload programs via USB key or Ethernet connection.

Fast input frequency up to 60 kHz allows for high speed counting and measuring applications
Up to 3 Presets for precision control (1 as absolute or trail preset, range or limit value; 2 with relay output)
Relay hold times programmable up to 10 minutes for a variety of application requirements
Prescaler adjustable from 0.0001 to 99.9999 for industry leading precision.

Conveyor Jam Protection – NK Technologies

When conveyors jam and the drive motor continues to run, expensive mechanical damage to the drive components often occurs. By installing an NK Technologies’ Current Operated Switch an overload condition, detected by higher than normal running amps, can be used to switch off power to the motor before mechanical damage results. The switch setting can be adjusted so it is not affected by normal changes in conveyor load. Current operated switches are the modern day equivalent of less reliable electromechanical jam relays that have been in use for many decades.

In situations where there may be large variations in load an NK Technologies Current Transducer can be used to monitor conveyor motor amp draw and output this data to the conveyor control systems, commonly a PLC. The PLC may be programmed to accomodate different setpoints for different mechanical loads so that jam protection is provided from light to heavy loads. In situations where the conveyor is not able to accept analog signals NK Technologies has developed a patented transducer with a frequency output suitable for the Digital Inputs of most PLC’s.

New Zealand Holiday

Part of the adventure in New Zealand. Not quite “White water rafting” or “Bungy Jumping”, but a lay-over for a cup of tea. Only in New Zealand. If you have been this way you will know where it is. State Highyway 4 – North Island New Zealand. Heading North in the Campervan for an overnight stay at Tongariro National Park, an some active Volcanoes.

Swiss Flow

HIGH PRESSURE FLOW METER:

The SF800/6 is the high-pressure version of the SF800 with extra metal enclosure. With an operating pressure of 250 bar and burst pressure of 750 bar, it is perfect for more demanding and high stress environments while retaining the versatility and other qualities of the SF800.

The inside of the sensor is similar to the SF800, and is made of high-quality plastics and composites with great chemical and thermal resilience and no susceptibility to limescale.

An integrated PCB emits the infrared signal, which is interrupted by the three blades of the rotor. SMD components transform the interrupted signal into a pulse. Because of the construction and geometry of the rotor housing, the Swissflow flow sensors can withstand high pressure.

Opkon Angle Sensors

OPKON’s core product has traditionally been Resistive Linear Position Transducers. These position sensors are commonly applied in plastic injection machinery, textile machines, transfer and hydraulic, metal forming machines and general automation applications. In the recent years, OPKON has started production of rotary magnetic encoders and linear magnetic incremental sensors, and Rotary potentiometers for Angle Measurement.

Signal outputs from 0-5vdc  over a rotation angle of 45°, 90°, 180° or 360°, with IP Rating of IP-64.

Models are available in a male shaft version c/w Flexible coupling and Mounting bracket, or a Blind hollow shaft version with flexible tether mount.

Namco Limit Switches

Namco Controls has been in the heavy industrial control sensor business since 1937 with our first Snap-Lock® limit switch, a name synonymous with rugged reliability under brutal conditions. Today, we are the only source for limit switches for use in Nuclear Power Plants qualified to NRC requirements, with installations around the world.

When non-contact electronic sensing was required, first in automotive assembly lines, Namco was the first U.S. company to respond. We patented internal short circuit protection for 2-wire sensors and developed the first weld field immune (WFI) sensors to survive resistance welder applications, positioning Namco as a recognized leader in high reliability electronic sensing. In fact, reliability is so important to our customers that we introduced the industry’s first Lifetime Replacement Program for electronic sensors in 1987.

GP-50 Model 340 Pressure Transmitter

GP:50 announces the release of yet another product to further complete their full line of upstream oilfield pressure and temperature transmitters. Working in conjunction with a major well servicing company, GP:50 developed the Model 340-IM series pressure transmitter specifically designed for blender discharge pressure applications. The Model 340-IM resolved the chronic high failure rates they experienced with other suppliers.

Designed for direct pipe mount via its flush process pipe connection the Model 340 series can handle the pressure and harsh media found on Frac blender trucks.

The Model 340 transmitter offers a compact, all welded, rugged design with a flush faced sensor that resists clogging found with conventional pipe mounted transmitters. With at least 5 times proof pressure, and a machined stainless steel sensing diaphragm, it can withstand erosion from aggregate and survive high pressure spikes typically found in blender applications.

With a proprietary sensor design there is zero installation offset, typically found with flush NPT process devices. Available in 4-20mA, 0-5 VDC or Canbus J1939 outputs and pressure ranges from 0-75 thru 0-1,000 PSI.
