T F2 ROTARY PUMPS

Increased service life

The FLG 12/01-LC miniature liquid pumps are designed with an improved shaft seal and corrosion-resistant features that bring the pump's life expectancy to more than 1,000 hrs. Rotary vane technology offers pulseless, reversible flow and quiet operation. It comes with a 12V (nominal) permanent magnet dc motor, able to operate at 4-15V dc. Intended applications include general liquids dispensing, fuel cells, coolant circulation, food and beverage lines, and condensate removal systems. Rietschle Thomashttp://rbi.ims.ca/4390-626

FLOW SWITCH

Easy to install, adjust

The Innova-Switch flow and level switch accomplishes detection by using a high-resolution thermal differential technique. The sensor consists of a pair of matched RTDs. One RTD is self-heated using a constant dc current; the other is unheated and provides an accurate process temperature reference. The thermal differential created between the reference and the heated RTD pair is a function of the density and/or velocity of the media with which the sensor is in contact. It is designed to be easy to install and adjust. Sierra Instruments Inc.http://rbi.ims.ca/4390-627

SERVO DRIVE

Built-in trajectory generation

The DS2100 servo drive is engineered for the full digital control of brushless motors. It uses a high-power microprocessor system that provides increased current, velocity, and position closed loop performance. It features all digital control loops, multiple control modes, wide current range capability (11-180 A peak), built-in trajectory generation, and a modular design is configurable for various interfaces. It also offers global acceptability with excellent span of line voltages (65-510V ac). Mooghttp://rbi.ims.ca/4390-628

CARTRIDGE VALVE

Pneumatically operated

Designed for precision dispensing of all types of fluids (solvents, oils, silicones, glues, UV adhesives, ink, etc.), the CV629 is a pneumatically operated valve that is for use with a valve controller and reservoir tank. It can be integrated into an automatic dispensing robot or used as a bench dispensing valve. Shot sizes may be fine-tuned by turning the adjustment screw at the top of the valve, according to the company. Shot size and flow rate are controlled by the tip size, fluid pressure, and the duration that the valve is open. I&J Fisnar Inc.http://rbi.ims.ca/4390-629

FLOW SENSOR

With no moving parts

Designed with no moving parts to wear or foul, the Signet 2551 Magmeter is an insertion style, electromagnetic flow sensor for conductive fluid applications that contain particles, solids, and fibers. Intended applications include flow monitoring in a range of industries, such as water and waste treatment, municipal drinking water, public pools and spas, aquariums, scrubbers, cooling towers, plating, beverage manufacturing, and power plants. It offers a variety of signal output options for user flexibility. George Fischer Inc. http://rbi.ims.ca/4390-630

TANKLESS WATER HEATER

With copper heat exchanger

The ProStar tankless gas water heater can be plumbed to serve a single fixture or multiple fixtures within the home. It is recommended for vacation homes, room additions, and other low-to-medium demand applications. The product is equipped with a copper heat exchanger and reportedly operates between 78-81 percent efficiency. According to the company, the tankless design heats water only when needed, with inputs modulating from 25,000 to 194,000 BTU, depending on hot water demand. A.O.

FLOW SENSORS

Accurate, convenient

Engineered for a wide variety of applications, the Flo-Tube flow sensors create and sense a pressure difference. When connected to the appropriate secondary instrumentation, the product provides an accurate and convenient method of flow measurement, according to the company. It features low permanent pressure loss, and customized units for existing mountings. Intended applications include pipelines (natural gas, fuels, chemicals), stacks (mixtures, emission monitoring), ducts (air flow, HVAC controls), water (potable, superheated, co-generation plants, building supply), among others.

CAPACITIVE LEVEL SENSOR

For small tubes and hoses

The TLS 100 is reportedly the first capacitive level sensor designed specifically for tubes and hoses. Its clip-on mounting design is engineered to reduce installation time and to permit a wider adjustment band for sensitivity. According to the company, it detects the presence or absence of liquids as a chosen level within plastic tubes, rubber hoses, and small glass or plastic pipes. Intended applications include the control of liquids in pharmaceutical manufacturing, food processing, chemical mixing, and detergent dispensing.

TESTING INSTRUMENT

Fast, accurate

The Sentinel F-21 testing instrument uses a solid-state mass flow sensor to respond rapidly to flow changes, resulting in faster test cycles. The 32-point calibration is designed to provide the most advanced and accurate flow measurement available, and it also uses tandem regulators to assure a constant pressure source for reliable mass flow readings. It also offers simple operator panel, dual pressure testing capability, a self-test feature, and the ability to store 1,000 test results for output to a printer or computer.

PTFE CONDUIT

Protects wiring, transports fluids

The company's line of PTFE tubing is offered in several configurations for protecting wiring or transporting fluids in critical applications. It is designed to be a conduit for protecting wiring in harsh environments and transporting fluids where a chemically inert and nonflammable material is required. It features plain, corrugated, and conflated styles. M.M. Newman Corp.http://rbi.ims.ca/4390-635

HEAT TRAP FITTINGS

Quiet operation

The Hush heat trap fittings feature a newly designed ball that reportedly reduces the possibility of "rattle" in water heaters. They incorporate a thermoplastic ball with an elongated "tail," according to the company, and during the flow of water the tail is forced to the interior surface of fitting, reducing the possibility of noise or rattle. In addition, they are also designed to help water heater manufacturers meet DOE efficiency requirements by reducing heat loss as well as providing safety relief ports that can prevent accidental closure of the waterway.

HYDRAULIC PUMPS

New sizes

The company has introduced two new pump sizes to their line of PVM medium-duty axial piston hydraulic pumps. The PVM-065 offers a Theoretical Maximum Displacement of 3.96 inches3/rev, and the PVM-075 provides a displacement of 4.58 inches3/rev. They provide a maximum peak pressure of 4,250 psi. Control options include pressure compensation, adjustable load sense, fixed load sense, as well as electrohydraulic proportional pressure compensation. The Oilgear Co.http://rbi.ims.ca/4390-637

PRESSURE TRANSMITTER

With optional three-way valve

The Series 629 Wet/Wet Differential Pressure Transmitter features an optional three-way valve that is fit for monitoring differential pressures on HVAC equipment. The optional integral valve manifold is designed for simple installation by allowing the installer to isolate or combine the pressures on the high and low pressure ports. It reportedly is also a suitable maintenance tool that provides the capability to perform maintenance on the transmitter without interrupting the process, according to the company.
