Gerald Ondrey and Scott Jenkins

Level Controls

Extend level measurement
with this flexible probe

The Procap capacitance probe (photo) features a flexible, extendable cable design for high-, middle- or low-level detection when the probe must be mounted on top of the bin. The device is especially suitable for applications where a probe is used as a high-level alarm or needs to be extended more than 4 ft. This flexible probe is also suitable for use with any lump material that might bend, damage or break a rigid probe. The first ten inches of the probe are rigid and the rest of the probe is flexible. The cable can be any length up to 35 ft. — BinMaster Level Controls, Lincoln, Neb.

Hans Turck
Now HMIs are also
offered by this firm

In addition to sensors, fieldbus, interface and connectivity solutions, this firm now also offers a new product line of human machine interfaces (HMIs). The VT250 (photo) is the first model available — other models will follow next year — and it provides visualization, controlling and variable gateway functionality for communication between fieldbus structures and realtime Ethernet. The VT250 has a 5.7-in. touchscreen, and can be configured as a master or slave, regardless of the communication direction. Providing two realtime Ethernet ports, the VT250 allows the user to set up a line topology. A communication port supporting RS 232 and RS 485, and the additional USB port are also included. — Hans Turck GmbH & Co. KG, Mülheim an der Ruhr, Germany

Emerson Process Management
This one transmitter
does the job of ten devices

The Rosemount 3051S MultiVariable Transmitter (3051SMV; photo) measures three variables and provides mass and energy flow output, thereby reducing the number of devices traditionally required to make differential pressure (DP) flow measurements from ten to one. The 3051SMV simplifies mass and energy flow measurement, increases accuracy and provides faster updates through patented, advanced compensation techniques. Full compensation of over 25 different parameters achieves a five-fold improvement in flow performance compared to uncompensated DP flow, says the manufacturer. The device updates flow measurement 22 times per second, enabling users to effectively track production, demand and total usage for process gas, steam and natural gas. — Emerson Process Management, Baar, Switzerland

Michell Instruments

Do more with this
dewpoint transmitter

The Easidew PRO I.S. (photo) is a rugged, intrinsically safe, dewpoint transmitter suitable for use in the natural gas, petrochemical and process industries. The device is ATEX-certified for use in hazardous area Zone 0, as well as for use with galvanic isolators. As with other transmitters in the Easidew Range, the PRO I.S. is part of the Sensor Calibration Exchange Program, enabling users to maintain traceability through periodic recalibration while keeping the process in operation. All the calibration data are stored within the transmitter’s flash memory, so calibration exchange, or service, can be affected in seconds. — Michell Instruments, Ely, U.K.

A new motorized actuator
for linear valves

This firm has introduced a new motorized open/close actuator for globe and diaphragm valves. The 24-V d.c. actuator (photo) is an alternative to current designs and also to solenoid valves. Valves using this actuator are especially suited to applications without plant air. Also, the operating costs of the motorized actuator are said to be lower than those of a comparable pneumatic actuator or even a solenoid valve. The actuating speed is between 4–10 mm/s, depending on the nominal size. The S680 diaphragm valve, for example, closes in about 0.5 s in nominal size DN 15, and about 2 s for DN 25. The design of motorized diaphragm valves makes them insensitive to particles and solids in the medium — even grains of sand and pieces of lime scale in water pipes impair neither the function nor the tightness of the valves. — GEMÜ Gebrüder Müller Apparatebau GmbH & Co. KG, Ingelfingen-Criesbach, Germany

Michael Smith Engineers
Aggressive media are not a problem

The system has a maximum, standard process-gas flow of more than 16 L/min of silane, 200 L/min of H2 and 40 L/min of NF3 — all of which are commonly used during the CVD processing step in solar-cell manufacturing. In addition, most dopant materials, such as phosphine, diborane or trimethyl borate, as well as etch materials, can be abated and processed effectively by these units. — Edwards Ltd., Crawley, U.K.

Keep flange leaks from
spraying with this shield
Allison Engineering

A new type of TÜV-approved, stainless-steel spray guard (photo) provides effective protection from dangerous spray-outs of fuel oils and other flammable liquids from pipes and flanges. The safety shield incorporates a steel band and an internal stainless-steel mesh that wraps around flanges and valves. The mesh is designed to sit against the flange — between it and an outer steel band — and compresses against it to ensure that sprays or leaks are dispersed, while also preventing lateral spray. The shield has been pressure tested to 50 bar, and has a quick-release connection for simple installation and removal. — Allison Engineering, Basildon, U.K.

A migration solution
for fail-safe controllers

All Excellence XP analytical and microbalances are equipped with adjustable, motor-driven windshields, which make operating the balance much easier and faster, especially when wearing gloves. The balances can be operated with two built-in SmartSens infrared sensors and up to two optional ErgoSens sensors. All weighing operations, including opening and closing the windshield, zero, tare and print/transfer results, can be performed without introducing any impurities. The windshields can be quickly removed and washed, and the mechanical concept of the SmartGrid hanging weighing pans means there are no difficult-to-reach gaps for ease of cleaning. — Mettler Toledo GmbH, Greifensee, Switzerland 

A new exchange resin
for industrial water treatment

Last month, this firm launched a new generation of gel-type, cation-exchange resins for industrial water treatment. Lewatit MonoPlus S 108 and S 108 H have optimized leaching behavior, which is an important quality characteristic regarding the effectiveness and commercial efficiency of an ion-exchange unit; the lower the resin’s tendency for self-leaching, the less total organic carbon (TOC) is released, says the firm. This release of organic substances is undesirable because it can lead to blocking of the anion exchanger. The new resin beads also remain in excellent condition after many operating cycles. Even with short cycle times, the special monodisperse ion-exchange matrix ensures long service life. — Lanxess AG, Leverkusen, Germany

Gear pumps that can also handle
highly viscous food additives

Gear pumps are commonly used for applications where fluids with high viscosities, high pressures and high temperatures have to be handled. Now, this firm has redesigned a gear pump, which has been used for years for conveying highly viscous, molten plastics, to handle all other chemical fluids with similar properties, such as resins or silicones, polyurethanes and polymer solutions, and highly viscous food additives. The pump features a slim construction and a large inlet, which makes it possible to reduce the net positive suction head required to be as low as 100 mm Hg. The design is capable of reliably conveying viscous fluids from vacuum containers. — Maag Pump Systems AG, Oberglatt, Switzerland

Avoid kinking on tight turns
with this tubing

Tex-Flex fluorinated ethylene propylene (FEP) corrugated tubing (photo) can turn sharp corners without kinking. The manufacturer asserts that the tubing can handle bend diameters four times smaller than a typical smoothbore tube of the same size. The tubing’s ability to bend without kinking makes it perform well in confined spaces, wrapping around machine legs and other obstacles that would normally restrict or kink a smoothbore tube. Tex-Flex corrugated tubing is lightweight, seamless and clear, allowing operators to monitor material passing through the tube. Tex-Flex is also offered in a high purity polyfluoroalkoxy (PFA). For higher-pressure applications, the tubes can be stainless-steel braided. Available sizes range from ¼ to 2 in. — Parker Hannifin Corp., Fort Worth, Tex.


A magnet operates
on this rupture-disc sensor

The Flo-Tel rupture disc detection system (photo) is a noninvasive sensor that operates with a reed-switch and magnet technology. The design avoids several challenges of standard rupture disc sensors. Some sensors require replacement or rewiring after one use, and are often in contact with the process flow, creating possible leak paths. Designed to work with the Opti-Gard rupture disc, the Flo-Tel sensor positions a magnet over the rupture disc so that when the disc bursts, the magnet and disc arc away from the sensor, creating an open circuit signal. After rupturing, the disc is the only element of the system requiring replacement. The sensor is not in contact with the process flow, so there are no potential leak paths. — Oseco, Broken Arrow, Okla.
