Products

Vibration Transmitter
This simple two-wire transmitter wired directly to a PLC or DCS provides early warning of impending problems and 24–7 protection against catastrophic failure. No wiring or special electronics are necessary. The ST5484E vibration transmitter features the Independent Polarity Terminal™ circuit to eliminate sensor wiring errors. It is designed to have a stable detection circuit and can handle a high operating temperature. Metrix Instrument Co. (Houston). www.metrix1.com

Tank Covers
Environetics Tank TopTM Covers are custom-manufactured from industrial-grade materials to fit the profile of a new or existing wastewater treatment tank. The covers are designed to be a cost-effective alternative to aluminum or fiberglass roofs. Heavy-duty aluminum extrusions and a high-strength membrane provide structural integrity for winds up to 110 mi/h and snow up to 35 lb/ft2. Aluminum framed hatches allow easy access to the tank for service, monitoring, and testing. Environetics Inc. (Lockport, Ill.). www.environeticsinc.com

Timer
The Traceable® Clip-It Timer is designed to clip to a lab coat, belt, notebook, or clipboard. It may be programmed in the “countdown mode” in 1-minute increments, from 100 hours to 1 second. At zero, a loud, beeping alarm sounds for 60 seconds or may be silenced manually. In the “stopwatch mode,” it times from 1 second to 99 hours and then repeats. It has a time-out feature in both up and down counting, and the big-digit, 0.33-in.-high display is easy to read. Five-button operation is quick and intuitive, and stopwatch operation takes just the press of a single button. Control Co. (Friendswood, Texas). www.control3.com

Cloth Media
OptiFiber® cloth media are designed to offer unique performance characteristics, a variety of materials of construction, solids storage depth, less operator attention, and fewer maintenance requirements. The media are suitable for tertiary filtration, reuse, and phosphorus removal applications and are available exclusively with AquaDisk®, Aqua MiniDisk®, AquaDiamond®, and AquaDrum® filters. Aqua-Aerobic Systems Inc. (Rockford, Ill.). www.aqua-aerobic.com

Interface Switch
Built to comply with process industry precision requirements for flow, level, and interface sensing in liquid, gas, or foam, the FLT93 Switch Series is now rated Safety Integrity Level (SIL) 2 compliant. The FLT93 Switch Series has been classified as a Type A subsystem in accordance with IEC 61508-1, with a hardware failure tolerance of zero. The probability of failure on demand meets SIL-2 capability standards. These thermal mass flow switches are designed for precision flow measurement, high reliability in rugged operating conditions, low maintenance, long life, and low cost of ownership. Their microprocessor-based designs feature a no-moving-parts thermal mass flow sensor. Fluid Components International (San Marcos, Calif.). www.fluidcomponents.com

Coaxial Valves
This line of VAX valves is suitable for applications that require fast actuation and strict durability and reliability. These compact valves combine a process valve and actuator in a single integrated unit with only one moving part. The VAX valve has a coaxial design offering high flow rates with minimal pressure loss while extending the VAX’s cycle life by as much as 10 times that of conventional valves. The electric version of the VAX functions like a direct-acting solenoid valve. Durability is a key advantage to the VAX valve. These valves do not leak, and the coils do not burn out.

Data Logger
These battery-operated data loggers feature portability and waterproof construction. With a temperature range of –60°C to 150°C, they are suitable for measuring and recording temperature in normal outdoor conditions, as well as harsher frozen environments, frozen storage, and high-humidity situations. They have large LCD displays, an “out of range” alarm function, and can log up to 16,000 readings from 1/sec to 1/h. They have a battery life of up to 4 years. TandD Corp. (Saratoga Springs, N.Y.). www.tandd.com

Pump Controllers
PumpLogixTM Controllers, designed exclusively for cutting-edge wet-well-mounted pump stations, are powered by microprocessor technology and come in two series options. The powerful L-Series model provides liquid-crystal display and complete pump-station control, including simplified VFD programming. The P-Series model provides pump control, monitoring functions, and level simulations. Both series can be supplied on new equipment or as a package to be used in an existing control panel or inserted into a complete replacement control panel.

Liquid Filter Bags
The new line of SchroederPURE liquid filter-bag systems is constructed to withstand pressures up to 150 psi. Available in a variety of sizes with flange, cover, and seam options, the systems help increase the level of product quality and lower labor costs by removing larger levels of contamination and recovering expensive materials that can be lost in the filtration process. The filter bags offer increased quality with reduced costs, making them ideal for applications that include wastewater biochemical oxygen demand and chemical oxygen demand filtration, recirculation of water and coolant, protection of instruments and actuators, prefiltering for high-pressure pumps, and removal of oversize particles and precipitated solids. Schroeder Industries (Leetsdale, Pa.). www.schroederindustries.com

Inoculation Turntable
These new turntables are designed for Inoculation of Petri Dishes up to 150 mm in diameter. They can be operated with touch-free IR-Sensor technology or with an optional foot pedal. They offer flexible start–stop functions or the second-timer control with variable rotational periods from 1 to 125 seconds. The Sensorturn features a continuously variable rotational speed control with a range of 14 to 110 rpm. The Sensorturn pro range is 14 to 210 rpm. WLD-TEC (Göttingen, Germany). www.wld-tec.com

Flowmeter
The FPD1000 series is one of three compact meters in the oval gear meter line. A variety of output and display options are available, including a reed switch or hall-effect sensor. The FPD1000D series, with a display, can handle a wide range of fluid viscosities with extreme accuracy. Meters come with a certification of accuracy, are designed to minimize the number of wearable parts, and are serviceable onsite. Omega Engineering Inc. (Stamford, Conn.). www.omega.com

Water Quality Controller
The HG-602 adapts to each site’s unique needs by allowing any combination of measurements in a single system, including free chlorine, pH, temperature, turbidity, conductivity, and flow. It provides versatile chlorine measurements and reliable wired and wireless communication. The controller offers simple, user-friendly menus and functions. Blue I Co. (Kfar Saba, Israel). www.blueitechnologies.com

Crane
The new 3000-lb davit crane features a fixed boom with the option for a hand-operated ratchet-style jack, five telescoping boom positions, mounting options for pedestal, socket, and wall installation, and a choice of hand-operated or power-operated winch units. The boom has a 112-in. maximum horizontal reach and a 153-in. maximum vertical reach. Thern Inc. (Winona, Minn.). www.thern.com

Temperature–Humidity Monitoring Tools
