Current to Voltage Transducer

Current to Voltage Transducer CR4310/11 Series produces a 0-5 Vdc output signal that is directly proportional to the input AC current. The output signal is average-sensing, calibrated for RMS.

Current to Voltage Transducer CR4310/11 Series is used with process control and industrial instrumentation equipment. The DC output signal can be connected directly to a high impedance analog input of a computer or PLC without additional signal conditioning.

Classic Wind Speed Transmitter

Precision wind speed measurement. The low-inertia light metallic cup star and opto-electronic pick-up combine to give a starting threshold of only 0.3 m/sec (0.7 mph). An electronically regulated heating system keeps the ball bearings and rotating parts frost and ice free down to -35°C (-31°F).

The instrument is rated for 60 m/sec (135 mph) and 85°C (185°F). The Classic is ideal for process plants required to measure wind conditions. Standard analog outputs connect easily to data aquisition systems.

CGM Sealless ANSI Centrifugals Feature Magnetic Drive

Vanton magnetically driven ANSI pumps are ideal for handling corrosive, and hazardous fluids. They are constructed with a dual nonmetallic containment can assembly: PTFE for the inner can in contact with the process liquid, backed by a rugged FRP outer can. This innovative design minimizes troublesome eddy currents.  The pump conforms to Hydraulic Institute Standards and offers an air cooled, dry running, tertiary seal. Flows to 450 gpm (102 m3/hr), heads to 280 feet (85 m).

Vortex Cabinet Coolers

Vortex Cabinet Coolers are an affordable, low maintenance, and easy to install alternative for thermal management of electrical cabinets and control panels. Using filtered compressed air and vortex tube technology, Vortex Coolers provide cooling capacities to 5000 BTUH and maintain NEMA 4, 4X and 12 ratings.

Today's small and compact, multi-function electronic controls, variable speed drives, servos and programmable logic controllers are extremely sensitive to heat and contamination. Excessive heat causes components to "cook", digital displays to misread, controls to drift, and breakers to trip below their rated loads. The result is often lost productivity from machine or line shutdowns.

Extruder Rupture Disks

Extruder Rupture Disks are designed for reliable emergency relief of excess pressure since they instantaneously rupture at a specific predetermined pressure range. Skylark Controls model CBP Extruder Rupture Disk is designed specifically for use in plastic extruders. Each assembly consists of a stainless steel body and rupture disk. A rupture disk may be specified for primary relief in applications where pressure buildup can occur so rapidly that the response time of a relief valve is inadequate, such as in a polymerization reaction vessel.

High Capacity Ball Valves from Chemline Plastics

Chemline HC Series High Capacity Ball Valves are the only truly large port 6" ball valve manufactured to date in PVC, Polypropylene and PVDF. Most others offer a 4" valve with ends increased to 6" size. This valve is suitable for sewage, mild slurry or vacuum lines where an unobstructed flow path is required.

New Solids Transfer Pump From Australia Does What No Other Pump Can!

Supavac pumps reliably transfer flowable thick sludge, abrasive slurries, hazardous wastes and dry bulk solids where submersible, centrifugal and diaphragm pumps break down. They function as an automatic pump with 25” Hg. suction power and, as the material and operation demands, will automatically function as a high lift vacuum system with powerful airflow.

Advanced vacuum recovery pressure discharge patented technology. With no rotating parts and no moving parts in contact with the flow, high reliability has been the experience. Available for rental and purchase from coast to coast.

Melt Pressure Gauges

Melt Pressure Gauges from ONEhalf20 are totally mechanical devices. They offer ease of installation and maintenance. In addition these gauges are ideally suited to processors who require only visual indication of melt pressure.

Melt Pressure Gauges are available in two unique styles. The CTG style features a 6" rigid stem and 30" of flex capillary. The RTG style has only a 6" rigid stem. Other configurations of these two styles are also available.
In addition ONEhalf20 also offers these same mechanical gauges with 3.3 mV/Volt transducer output, or either 4-20mA or 0 - 10 Vdc transmitter outputs. These unique gauges feature the standard Bendix style 6 pin bayonet connector and are ideal for processors looking for localized visual indication at the extruder barrel.

EchoSwitch Multi-Point Ultrasonic Level Switch From Flowline

The general purpose ultrasonic level switch provides non-contact level detection up to 40' or 12.2m with 3 relays and 1-6 set points. Each relay can be configured on a single set point alarm, two latched set points for automatic fill or empty control or two independent set points for out of bounds alarming.

The switch is ideally suited for challenging corrosive, slurry or waste liquids and is broadly selected for atmospheric bulk storage, day tank and waste sump applications. Media examples include sodium hydroxide and wastewater.
