TEMPERATURE MEASUREMENT

ROUND UP

Humidity probe for tough processes

Michell Instruments, represented in South Africa by Instrotech – a Comtest Group company – has on offer their new HygroSmart HS3 probe, designed to withstand the kind of harsh and demanding conditions found in industrial processes. Unlike many ‘disposable’ probes that have a short life within harsh conditions before needing to be replaced, the HygroSmart HS3 sensor has a polymer tile to give long-term reliable measurements. In addition, it also has an accuracy of 0,8% RH, making it among the most accurate and reliable RH probes on the market, as well as allowing for longer recalibration periods.  This not only gives peace of mind to process operators, but also provides a low life-time cost of ownership when compared to the disposable probes.The HygroSmart HS3 consists of a solid, corrosion-resistant probe body with an interchangeable sensor.When recalibration is due, the old HygroSmart HS3 sensor is simply exchanged for a new, freshly calibrated one.This simple procedure takes only a few seconds to carry out with the probe itself remaining installed. Replacing just the sensor, rather than the whole probe, is not only quick and simple, it also saves users money over the lifetime of the probe.  In most industrial applications, RH probes have to withstand vibration, exposure to water, occasional heavy

shocks and high levels of electrical interference.The HygroSmart HS3 body is designed to cope with all these environmental factors. As well as the solid body, the probe also has a 10 bar pressure rating, rfi/emc electrical noise approvals and IP67 ingress protection rating.

Reduce risk of electrical injury

DeltaT Alert is a wireless, self-contained tempera- ture-monitoring sensor that attaches to an electrical enclosure cover. The patented, DeltaT Alert unit is simple to install and comprises two temperature sensors one to monitor the electrical enclosure's interior temperatures and the second tomonitor the room's ambient temperature where the enclosure is located. DeltaTAlert sensors are then configured to collect data on continuous basis, at preset time intervals. The data is wirelessly transmitted for analysis and trending and warns the operator of temperature rises within their electrical enclosures, well before

more serious problems arise and provides an easier, more effective way to prevent costly electrical dam- age and system downtime. Delta T Alert bridges the gap between your in- frared scans by monitoring and reporting critical temperatures within your electrical enclosures on a timed basis and effectively tracks your electrical system enclosure temperatures and sends data for analysis and trending. If a critical issue arises, immediate notification allows for an appropriate corrective action, before costly damage occurs. Enquiries:Tel. +27 (0) 11 608 1551 or email sales@randci.co.za

Radical aerial thermography

Optris, specialists in non-contact temperature measurement, has on offer to the market, the newly developed Optris PI LightWeight – a market innovation that allows for radiometric recordings of video imagery from the air. The combination of a miniature lightweight PC and a light version of the Optris PI thermal imager weighs only 380 g.The PI LightWeight is therefore ideally suited for maintenance work and quality inspections of solar and wind power systems and also for thermographic surveys of buildings. Mounted on a UAV, the Optris PI Lightweight allows recording of radiometric IR images and videos.The flight thermography sys- tem is therefore eminently suitable for error detection and quality inspections of solar farms and wind power systems.The innovative combination of a lightweight mini PC and a thermal imaging camera is also ideally suited for thermographic analyses of hard-to-reach places like roofs of buildings (building thermography) and it is al-

ready in use in agriculture where fields are being inspected before being mowed (presence detection). Optris is a German manufacturer of non-contact temperature measurement equipment.Their product range consists of portable and stationary infrared thermometers and online infrared cameras for thermographic real time analyses.
