High Intensity LED Module for Photochemical Flow Applications
Borealis™ from Uniqsis is a new high intensity LED lamp unit, available in a range of fixed wavelengths (370, 410, 440, 460 and 520nm), that converts their Cold Coil™ standalone reactor module into a flow reactor for pho- tochemical applications. Both the Borealis™ LED lamp and the Cold Coil™ reactor modules require liquid cool- ing from either a piped water supply or a closed loop re- circulator. Fitted with a safety interlock, to prevent accidental ex-
posure to high intensity light, the LED lamps are powered by a programable power supply that automatically de- tects the wavelength of the Borealis™ LED module and adjusts the output characteristics accordingly. A tem- perature sensor and safety cut-out are fitted to protect the LEDs from overheating. An Inert gas purge input is provided for low temperature use.

HVAC Sensor Accuracy – Did you know?
Ashcroft pressure sensors are manufactured to their TruAccuracy™ standard, which is based on the terminal point method. This means that these products meet their rated accuracies out of the box without the need for field calibration adjustments. There are many methods of calculating accuracy statements for pressure instruments, but not all
of them result in accurate accuracy statements. Ideally, an accuracy statement should include a summation of all the error sources – which is uncommon in the HVAC industry. At a minimum, accu- racy statements should include non-linearity, hysteresis, non-repeatability, zero offset and span set- ting, which contributes significantly to how well the instrument performs. While not all summation methods consider all of these errors, the terminal point method does by
including both the zero and span settings as part of the accuracy statement. Ashcroft chooses to use the terminal point method of calibration. This methodology truly determines the actual error for a pressure instrument, allowing manufacturers to better indicate the accuracy of their products and contractors to better manage the heating, cooling and subsequent low air flow in these building.

Watchdog Wireless sensors, software & vision cloud platform
and receivers if there is local noise from other wireless equipment or machinery/devices. The toolkit helps when setting up a system and makes deployment reliable and robust. Typical applications are where a company wishes to rapidly
deploy sensors for monitoring critical assets such as Engines, Presses, Generators, Gearboxes, Jacking platforms and Silo Levels etc. where laying cabling would be onerous, costly or time intensive. Wireless sensors can be moved from job to job if they are not required permanently in one location. Hydrotechnik have gained a lot of experience in deploying
Watchlog Wireless sensors and gateways in a whole array of settings. One interesting example is on major construction sites where excavated earth or structures need to be supported via hydraulic Jacks. Watchlog sensors are deployed to monitor the hydraulic pressure in each jack as well as any linear displacement of the asset being supported. Data is
Hydrotechnik’s Watchlog Wireless is a complete end-to-end solution for monitoring Pressure, Temperature, Flow, Displacement, Torque, Level etc. in a factory or mobile setting to get data from machinery to a local PC/on-site systems, or into the cloud for remote monitoring. Watchlog Wireless transmitters are capable of pushing data from
800m up to 1.6Km, depending on the transmitter selected and the factory/asset environment. Up to 60 sensors of varying types can sit on the same local wireless network and accessed by a single gateway. Gateways or receivers can be either local for monitoring
performance within a factory setting directly on a PC or HMI, or gateways can push data directly into the cloud for long term monitoring and alerting/alarming. When using a local PC free to use monitoring and trending software shows all sensors connected. A toolkit helps with locating transmitters
pushed to our Watchlog Vision cloud platform for long term monitoring however, the key to the success of these systems is the ability to set alarms if/when something changes. Our Watchlog Vision Cloud platform stores all measured data for
long term trending. Alerts can be set up to send text messages or emails to key staff when a value is breached. Wireless uptime is also monitored, and any outages are logged and can be alerted. Hydrotechnik have support staff to help deployment and can also facilitate 3rd party branding if required. The Vision cloud platform is a low cost monthly subscription model which can also facilitate separate branding and logins if required.
