19 Pressure Series DH Digihelic Differential Pressure Controller 3-in-1 Instrument: Gage, Switch and Transmitter DIGIHELIC 3-19/32 (91.28) INWC SP1 SP2 AL SP/AL MENU E RST 1-15/16 (49.21) 3-25/32 (96.04) 4-1/2 (114.30) 1-3/4 (44.45) 4-1/2 (114.30) 1/2 (12.70) The Dwyer Series DH Digihelic Differential Pressure Controller is a 3-in-1 instrument possessing a digital display gage, control relay switches, and a transmitter with current output. Combining these three features allows the reduction of several instruments with one product, saving inventory, installation time and money. The Digihelic is the ideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 5 to 100 in. w.c. The Digihelic allows the selection of pressure, velocity or volumetric flow operation in several commonly used engineering units. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4-20mA process output. The Series DH provides extreme flexibility in power usage by allowing 120/220 VAC and also 24 VDC power which is often used in control panels. Programming is easy using the menu key to access five simplified menus which provide access to: security level; selection of pressure, velocity or flow operation; selection of engineering units; K-factor for use with flow sensors; rectangular or circular duct for inputting area in flow applications; set point control or set point and alarm operation; alarm operation as a high, low or high/low alarm; automatic or manual alarm reset; alarm delay; view peak and valley process readings; digital dampening for smoothing erratic process applications; scaling the 4-20mA process output to fit your application s range; Modbus communications; and field calibration. With all this packed into one product it is easy to see why the Digihelic is the only instrument you will need for all your pressure applications.

We have been manufacturing true Premium efficient motors since 1977, and are now proud to offer you our newest AC motor for severe-duty applications the totally enclosed Reliance 841XL Premium efficient motor. When conditions are severe and dependability is beyond question, this AC motor is at its best. Designed and manufactured to meet or exceed IEEE 841 Standards, the Reliance 841XL motor offers unmatched reliability, energy efficiency, and performance. Its rugged design and extra- tough features minimize vibration, as well as provide years of low-maintenance service in moist, contaminated, or harsh environments.

2 R e l i a n c e 8 4 1 X L M o t o r s 3 Includes a 5-Year Warranty Confidence in the design and manufacture of these motors is why Reliance will repair or replace any properly installed 841XL motor

29 2 R e l i a n c e X L M o t o r s 3 Includes a 5-Year Warranty Confidence in the design and manufacture of these motors is why Reliance will repair or replace any properly installed 841XL motor that fails within 5 years of shipment. 4 7 Conforms to Energy Efficiency Standards: The 841XL motor meets or exceeds 1997 U.S. Energy Policy regulations. It also meets CSA Efficiency Verification Program requirements ) IEEE 841 Motor Standards 841XL NEMA Frame Motor Features Exceeding Specification Foot flatness tolerance is increased to a foot pad planity within inches for precision alignment to driven equipment and smooth operation. The draft angle on top of all mounting feet is 1.50 or less to make proper mounting easier. 6 High strength cast iron frame is designed to reduce vibration and assure accurate mounting dimensions. Durable cast iron end shields are machined to close tolerances for exacting alignment of bearings and rotor. All hardware is hex head, high strength and zinc-plated. All internal rotor, stator and shaft surfaces are epoxy coated. 1 Embossed stainless steel nameplates include all required NEMA data plus actual motor weight and guaranteed minimum efficiency. 2) Quiet Operation Operating sound levels are below 90 dba sound power. 3) Longer Winding Life Non-hydroscopic, chemical and humidity resistant Class F insulation. Class F insulation consists of Class F and H materials for higher temperature resistance. Coil heads are laced on both ends to prevent movement prior to a heavy build application of varnish. All windings are tested before and after insertion into the frame to NEMA MG.1 high potential voltage standards. Insulation system meets the requirements of NEMA MG.1 Part 31 Section IV for VFD use and are considered inverter capable. 4) Reduced Vibration Rotors are dynamically balanced to 0.04 inches-per-second peak-to-peak velocity. Every motor is guaranteed to meet IEEE 841 vibration standards. A vibration test report is shipped with each motor. Precision cast conductor bars on the rotor minimize vibration and extend service life. 5) Increased Energy Efficiency Motor efficiency exceeds the requirements of the 1992 U.S. Energy Policy Act. Motor efficiency meets or exceeds Canadian Federal Efficiency Levels defined in CSA C

30 M e e t o r E x c e e d I E E E M o t o r S t a n d a r d s For long life and superior protection, the 841XL motor features the exclusive Positive Lubrication System Plus (PLS ), which channels grease directly into the bearing track, and Inpro non-contact labyrinth seals, which are incorporated on both ends. Reliance motors are available in over one-million ratings, types, styles, and sizes from fractional to 25,000 horsepower. 841 Features may vary for non-nema ratings. 6) Protected Electrical Connections Corrosion-resistant oversized cast iron conduit box exceeds the volume required by NEMA standards. Neoprene conduit box gaskets prevent the entry of moisture and contaminants. All motor leads have lugs for easy electrical connections. A drilled and tapped hole for a ground lug is provided on the frame. A clamp type ground lug is provided in the conduit box. 7) Longer Bearing Life Bearing lubricant life is increased by minimizing temperature rise to below 50 o C for 2 pole motors and 45 o C for 4 pole motors. Automatic grease reservoir drain plug with spring-loaded relief (Gits Cup) extends out of the fan cover. Bearing contamination from moisture, dust, dirt, or other materials is prevented with the installation of Inpro bearing isolators on both ends of the motor in all frame sizes. Bearings are sized to provide high load capacities and degassed for maximum durability. Exclusive PLS Plus (Positive Lubrication System Plus) assures proper bearing lubrication in all mounting positions. It channels grease directly into the bearing track. Easily accessible lubrication fittings are positioned in the front and back end shields. Cast iron bearing inner-caps provide accurate alignment and prevent bearing contamination. 8) Closer shaft Tolerances Permissible shaft runout is reduced by 50% of previous standards inch (T.I.R.) for shaft diameters to inches, and inch for larger shafts.
