Single-beam safety switch; Embedded software solution aids automation of multiphase flow measurement

Single-beam safety switch

SICK has unveiled its next-generation L25 and L26 family of single-beam photoelectric safety switches, equipped with BluePilot alignment and IO-Link for smart, real-time communication, ensuring maximum machine uptime while protecting personnel from hazardous machinery.

With a scanning range up to 50m, the SICK L25 and L26 are Type 2 devices available in visible red light and infrared (IR) versions to meet a wide range of safety applications up to PL c (SIL 1). The IR and red-light versions could also be used together to avoid the potential for signal interference and introduce redundancy for applications requiring a higher level of safety.

The rugged and robust single-beam safety sensors are suited to use for collision- or access protection of barriers, gates, doors or racking systems, including multiple access points at longer scanning distances. With the ability to cascade up to four pairs of sensors, they can also be combined to achieve effective perimeter guarding of machines, or access protection to robot cells or machinetending areas, including the option of replacing a light curtain in space-limited machine designs.

The L25 has a scanning range up to 20m, and the L26 up to 50m.

Temperature transmitter for hazardous areas

Vaisala has launched a new humidity and temperature transmitter series – HMT370EX – for applications in hazardous and explosive environments.

The entire transmitter can be installed directly in explosive areas, up to zone 0 and zone 20.

A rugged display allows the unit to withstand continuous exposure to potentially explosive areas that contain flammable gases or dust. Typical applications might include paint booths in the automotive industry, hydrogen cooled generators in electricity generation, chemical plants and processes, baking industry, pharmaceuticals manufacturing, oil and gas drilling platforms, and fuel tanks and storage.

The range consists of the transmitter and a selection of probes. The transmitter is equipped with an intuitive graphical display for ease of use. Hand-detachable measurement probes and easy product configuration and calibration with Vaisala Insight PC software is said to enable smooth maintenance, minimising any measurement downtimes. In addition to measuring relative humidity and temperature, the transmitter also outputs dew point temperature, wetbulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, water vapour pressure, and enthalpy.

Embedded software solution aids automation of multiphase flow measurement

Emerson has introduced a new software solution to boost process automation and the application of its Roxar 2600 multiphase flow meter (MPFM) for the oil and gas industry.

The Rapid Adaptive Measurement software architecture is said to enable the Roxar 2600 MPFM to do parallel computations at 10 Hz and autonomously select the optimal configuration for a particular time period. This leads to more automation in operational processes, reducing the need for what previously were manual configuration changes.

As oil and gas operators adjust production methodologies to develop more complex reservoirs, the flow profile of wells is becoming more varied. Producers therefore need multiphase flow metering technology to be robust and reliable in very demanding conditions.

The Roxar Rapid Adaptive Measurement software supports operators with meter performance, increased robustness and confidence while enabling cost-efficient operations. The modularity of Rapid Adaptive Measurement allows for individual calculation modules to be improved and tested independently, and new modules can easily be plugged into the framework.

This enables the embedded calculation software and, by extension, the Roxar 2600 MPFM performance to evolve with new modules as they become available, providing continuously updated support for the life of an oilfield.
