LEE-DICKENS NAMUR NE43 TRIP AMPLIFIERS ACHIEVES SIL2 RATING


ee-Dickens have four trip amplifiers that comply with the NAMUR NE43 recommendations. These non-processor based trip amplifiers have been assessed to IEC61508 and achieve SIL2 rating with a proof test interval of one year. The NAMUR NE43 recommendation document sets out to define the “Out of Range” figures that are to be used with the industry standard 4 to 20mA signal. The four trip amplifiers have the standard process trips as well as an independent “out of range” trip. The “out of range” trip is activated when the input signal either falls below 3.8mA or exceeds 20.5mA. The SIL rated instruments are the BD9431/BD9432, which are AC powered Single/Dual


L


Level Trip Amplifiers respectively, and the BM9431/BM9432, which are DC powered Single/Dual Level Trip Amplifiers, respectively.

NEW LOW-COST BLACKBODY FOR THERMAL IMAGING SYSTEMS


T


his year, Isotech has supplied hundreds of the Model 988 Blackbody meeting an


unprecedented global demand for Thermometer Calibration. With the higher quantities required, we have been able to make cost savings and improved manufacturing efficiency. We have listened to our customers and the result is a new 989 model that is smaller and easier to mount, a wider temperature range and a PC interface. Response time is very fast, typically less


than five minutes to achieve the required temperature. The new Model 989 can be used either horizontally or vertically and features a high emissivity ridged plate that is 70mm in diameter and its temperature can be set from 20°C to 50°C to a resolution of 0.01°C.

MEASURING VIBRATIONS AT UP TO 1000 DEGREES CELSIUS


delivers reliable results at temperatures up to 700 degrees Celsius over the long term and up to 1000 degrees for short periods of time. The 8211A sensor is certified to ATEX and IECEX for use in explosion protection making it suitable not only for monitoring purposes, but also for use under extreme conditions in a wide variety of applications.


A


Differential measurement chain ensures reliable results The core technology of the 8211A accelerometer is based on the piezoelectric effect: the accelerometer generates an electrical charge that is proportional to the acceleration. In combination with a differential charge amplifier this provides a complete and stable dif- ferential measurement chain that is not influenced by environmental factors such as electromagnetic interference.

HSE TESTING CONFIRMS CASELLA CYCLONE AIR SAMPLING HEADS RELIABILITY


and Safety Executive (HSE) to undertake testing of its Cyclone Air Sampling heads to ensure that the heads meet the ACGIH/ISO/CEN (EN 481) standard. The intensive testing has confirmed that Casella’s Cyclone sampling heads meet this standard when sampling at the published flow rate of 2.2 litres per minute. Every Cyclone is manufactured to sample respirable dust at a specific air-flow rate; if the cyclone is not sampling correctly at the specified flow rate the concentration of dust can be over or under estimated; a concerning outcome when poor data could have a direct and negative impact on workplace safety and worker health. “The confirmation from the HSE that our Cyclone heads operate as intended is welcome news”, says Tim Turney, Casella Global Marketing Manager.

FLOWMETERS HELP REDUCE DRUG PRODUCTION COSTS


T


itan Enterprises Atrato and MetraFlow ultrasonic inline


flowmeters are used by drug manufacturers to streamline production and reduce costs. These devices measure a liquid’s rate of flow with extraordinary levels of accuracy, helping drug manufacturers control small details that make a big difference during production. Production of pharmaceutical drugs presents difficult challenges for process instrumentation used to monitor and optimise the process. Typically drug production processes require devices able to cope with low flow rates and constructed from ultra- pure materials so as to maintain hygienic, sterile and sanitary conditions.
