NEW Cyclops L - portable non-contact thermometers
New pressure controller
H
WM has launched a new electronic controller for pressure reducing valves (PRVs). Pegasus+ enables detailed multi-point PRV control without a flowmeter, either by flow or by time, together with sophisticated closed loop control. The controller permits immediate control of pressure within a distribution network, and automatically adapts to network changes and events by analysing data from up to three critical points (CPs). By controlling PRV output pressure,
Pegasus+
maintains CP targets defined in terms of time, flow or a combination of the two. Networks can be optimised to reflect changing demand throughout the day or week. In extreme or emergency situations, a latching solenoid output enables valves to be fully opened or closed according to controller settings. Bidirectional GPRS telemetry can be used to trigger alarms or remotely control the valve. In addition to its main logging channel, Pegasus+ features a secondary channel for fast logging down to one-second intervals. This allows for a more detailed investigation of events such as pressure spikes and helps to establish actual minimum night flow. Pegasus+ offers the ability to control a network from any web-enabled device. Via the HWM Online web viewer, users can check and alter system and component configurations and settings. A tablet or PC-based app facilitates controller set-up and programming.

ith its internal data logging capabilities, configurable route modes and dedicated software, the Cyclops L further establishes AMETEK Land as the industry leader in high-quality, portable non-contact temperature measurement. There are four new models in the new Cyclops L family, measuring across the range 200°C/392°F to 3000°C/5432 °F. They are aimed at a wide range of applications including liquid metal, steel and glass production, furnaces, plus many others. The Cyclops L family features the new Route Manager function, which enables users to configure a path/route around a plant by identifying the location with description, an emissivity value, a window correction factor (if applicable), and a unique identifier (a description). This Route Management mode allows for complete repeatability of readings, making the thermometer the ideal tool for multiple locations requiring regular and reliable monitoring.

Miniature laser retro-reflective sensor BOS Q08M B
Advertorial
alluff miniature optical sensors from the BOS Q08M series have an impressively compact design and achieve extreme precision in
a robust, cubic metal housing. They are suitable for all applications requiring components with a low weight,
minimal space
requirements and maximum switching precision, e.g. on robot gripper arms and mini grippers. A laser retro-reflective sensor is the latest addition to this range of mini optical products. The laser retro- reflective sensor from laser class 1 can reliably detect parts as small as 0.3 mm at a switching frequency of 400 Hz and is therefore the right choice for even the most demanding positioning tasks. The sensor with sharply focused laser beam and a maximum working
range of one meter is also the perfect solution for detecting machine components positioned among groups of tightly packed parts in restricted spaces. The laser retro-reflective sensor operates as a normally open or normally closed contact and is optionally available with NPN or PNP output in a cable or pigtail variant. The sensor is connected via a three-pin M8 plug. There is also a patented matching clamp holder for rapidly positioning 8 x 8 sensors flush in aluminum profiles.

ICK is launching an Optical Character Recognition (OCR) version of its Lector 620 scanner for packaging applications, making combined alphanumeric character and barcode reading, quality-checking and matching, faster, simpler and more reliable than was previously possible. SICK’s new LECTOR 620 OCR combines Optical Character Reading,
Optical Character
Verification, 2D and barcode reading in a single device. It delivers outstanding reading capability with ease of set-up in a compact, competitively-priced sensor.
Using machine vision-based
technology can be a vital weapon in the battle to ensure pharmaceutical, food, cosmetics and FMCG products leave the factory with alphanumeric labelling information fully readable, matches the product’s barcode and is fully traceable. Application Specialist for Imaging & Measurement at Sick:
“Pharmaceutical, Food, FMCG,
cosmetics packaging still needs human readable on-pack data, such as batch, lot numbers and best- before expiry dates.
SICK spent several years researching the best decoding algorithms before developing the LECTOR 620 OCR to achieve outstanding speed and read reliability.
Says Neil Sandhu, and
These numbers, letters, symbols and codes need to be verified, be of a readable quality and match the barcode to ensure the right data is associated with the right pack. It’s the only cast-iron way for manufacturers to save punitive fines and comply with the requirements of retailers and the law.
With simple swivel-connector
mounting, installation is quick thanks to the scanner’s aiming laser, focus adjustment, and auto-setup. With a built-in facility to teach font changes ‘on the fly’, there’s no need to stop the line for product changes. The SICK LECTOR 620 OCR permits plain text letters, symbols and numbers at distance of between 30mm and 300mm to be detected both while stationary and at speeds of up to 4.0 m/s. A range of standard fonts are supported, as well as barcodes and data matrix codes, ensuring both legibility and placement for essential quality control. The device incorporates a microSD card for image storage and parameter back-up memory.
The teach-in of fonts and
commissioning for the LECTOR 620 OCR are rapid and easy, done at the scanner rather than remotely from a PC, and can be performed from the running production line. The integrated font training wizard provides intuitive teach-in and fonts can be cloned to other LECTOR 620 OCR scanners, saving time in full line commissioning and the font locator function ensures easy reading of moving fonts.

interface versions of popular contactless rotary
Two CAN bus position sensor
enny + Giles – a business group of Curtiss-Wright Controls and designer and manufacturer of high precision sensing technology - has continued the development of its SRH500 range of contactless rotary position sensors with the introduction of two CAN bus interface versions. The SRH520CN is a development of the company’s existing SRH501/2P model.
It
integrates additional electronics to provide either J1939 or CANopen options according to ISO/DIS 11898. Both versions also feature a 14 bit non- contact Hall effect sensor offering 0.022° resolution. Historically,
position sensors were connected indirectly to CAN networks via analogue input/output (I/O) modules. More recently however, an increasing number of position sensors with integrated CAN interfaces have been developed which, like the Penny + Giles SRH520CN, avoid cost-intensive I/O or gateway modules. The J1939 version of the rotary position sensor is factory programmed by Penny + Giles to offer Direction, Baud Rate, Node ID and Frame Rate parameters. The CANopen version offers either Baud Rate or Node ID parameters, but is customer configurable to the CIA standard DS 301 protocol and supports the device profile for DS 406 encoders.
