PRESSURE + LEVEL MEASUREMENT

ROUND UP

New precision digital pressure gauge – enhanced performance spectrum Extended measuring ranges, large data log- ger, wireless functionality and streamlined menu operation: With the model CPG1500, WIKA has launched an improved precision digital pressure gauge with an appealing price/performance ratio.The new calibration and test instrument has been designed for versatile use. The CPG1500 covers pressure ranges up to 0 ... 1,000 bar andmeasures with an accuracy of up to 0,05% of span. Its data logger can record up to 50 measured values per second.The data is transmittedwirelessly and can be processed using theWIKACal soft- ware. Further functionality, such as min/max memory or integrated temperaturemeasure- ment, enhances the performance range.The newmenu structure of the CPG1500 enables a quicker intuitive input for all parameters. A 5½-digit display with bargraph and a large text field supports the analysis of measuring points on site. The measuring quality of the CPG1500 is ‘packaged’ within a robust design. As an intrinsically safe instrument (IECEx, ATEX, CSA approvals) and with IP65 ingress protection, it offers reliability and durability, even with extreme process conditions.

Launch of locally manufactured globe valve

Mitech ControlValves has launched a locally designed and manufac- tured High Pressure Globe StopValve. High-pressure stop valves are used in the most extreme high pressure and temperature applica- tions. Eskom remains one of the largest consumers of these valve types, with thousands of units required in power plants across the country. Up until now, there has been no local manufacturing capa- bility to produce the valves required to specification. With no local capability available, cost for the purchase and maintenance of these valves remains high. In answer to this challenge, Mitech has been working in close consultation with Eskom over the last two years, to conceptualise, design and locally manufacture a high pressure stop globe valve that will fulfil the technical and safety requirements as well as the local content requirements as set out inThe Department ofTrade and Industry’s (the dti) designation Instruction Note for the procurement of valves and actuators. General Manager for Mitech, Pieter Badenhorst highlights the degree to which the unit is locally produced stating that “although we have to import some of the material used in the manufacturing process such as bar-stock which is not produced in the country at present the valve remains 80 - 90% locally manufactured.” Using Mitech’s design, locally sourced materials, local castings, machin-

ing, assembly and testing, the valve conforms to all the criteria for local content. Badenhorst explains that it would be very difficult to simulate the extreme conditions that would be required to test their valve in the laboratory, and therefore, Eskom has agreed to install the valves at appropriate test sites for a trial period at their power plants, to fully evaluate the valve’s performance. Mitech has committed to provid- ing technicians working on Eskom’s plants with training as well as a full service manual to ensure effective incorporation of the valve into the power plants. The whole unit comprises 33 components, most of which are easy to maintain. The body of the valve is a one-piece investment cast design, eliminating threaded or bolted pressure retaining parts.The unit has a fully replaceable seat, which can be extracted while the valve remains welded into the line.
