70 Safety Intrinsically Safe Approval for Personal Samples Pump
Following a rigorous testing process, Casella has announced Intrinsically Safe approval for its Apex2 personal sampling pump range, with class leading performance and capability.
Instruments supplied for application in atmospheres where there is a risk of explosion must be designed with the appropriate safety requirement critical in achieving IS approval; protecting the equipment and ensuring it is safe to use. Achieving the IS certifi cation for the Apex2 range ensures that monitoring and analysis of dust exposure can be carried out safely and effectively in these areas. The range includes three separate models - the Apex 2, Apex 2 Plus and Apex 2 Pro, with different functionality to meet varying requirements; all designed to monitor workplace dust levels to help protect workers from developing long latency health problems as the result of occupational exposures.
Incorporating Bluetooth connectivity with Casella’s bespoke Airwave software; workers can be monitored remotely without being distracted, boosting productivity levels. Monitoring specialists can view the status of their dust sampling pump on a worker and start, stop or even pause the tool from a smart device. This software is simple and easy to use, providing real-time status updates, allowing collected data to be emailed alongside photos and notes, adding context to the data and further simplifying the reporting process.
Tim Turney, Casella’s product manager said: “Achieving the IS accreditation for the Apex2 sampling pump demonstrates our commitment to providing solutions that ultimately help to enhance the long term health and quality of life for workers operating in high risk sectors. The Apex2 IS has also gained the certifi cation without compromising the power and battery life that the Apex2 is known for, allowing it to be used with many types of air sampling media.”

39446pr@reply-direct.com Explosion Proof Gas Detector Heads
N.E.T. Srl introduces a new range of stainless steel fl ameproof enclosures housing gas sensors, dedicated to fi xed gas detectors in industrial applications. While standard NET heads are certifi ed as component, the new NETC heads have been tested and full conformity certifi ed as complete instruments according to the ATEX and IECEx normatives. NETC2: are completely sealed devices that can house a pellistor, electrochemical cell or NDIR sensor. Connection with the gas detector with ¾” or 1” thread and a M35 front thread that will allows easy fi t for accessories (splash guard, calibration cap and additional fi lter for GD and IP65 protection) NETC3: these bigger heads can be opened to replace the sensor at the end of the sensor’s life. They can house any gas sensor for fl ammable, toxic and refrigerant gases. Connection with ¾”,1” or M20 thread and additional M46 front thread for accessories. NETC3 Cyber Heads: same features as NEC3, in addition they also include a smart transmitter board which is calibrated at the requested fullscale and provides linear 4-20mA output, digital communication and fault indication. SIL2 approved (software and hardware). For latest news and full technical specifi cations, please visit the website. For specifi c questions and offers, you can contact N.E.T. directly.

Advanced NDIR Sensor for SF6 or Refrigerants Detection The IR series
of infrared gas detection sensors, from N.E.T. use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of SF6 or refrigerants. This technique is based on the fact that the gas has a unique and well defi ned light absorption curve in the infrared spectrum that can be used to identify the specifi c gas. The gas concentration can be determined by using a suitable infrared source and by analysing the quantity of energy absorbed from the gas inside the optical path. The IREF-P sensor is equipped with electronics and fi rmware in order to provide an output that is linearised and temperature compensated. The output is analogue voltage type [0.4 V—2 V] dc (other voltages are available on request). IREF P is now SIL2 approved.
The main features are: analogue voltage standard output, incorporated signal, linearisation and temperature compensation suited for instrument manufacturers without any specialist knowledge in IR technology, standard sensor size 32 mm, fast response, solid, rugged construction, wide operating temperature and humidity range (-20°C +60°C) and new optics “Variable Geometry”.
