Diaphragm-type differential pressure gauge 2000-0D 2001D 2002D 2003D 2004D 
 Select Dwyer Magnehelica pressure gauge can be obtained less than 2% full scale precision, and as many as 81 kinds of range selection, accuracy to meet the needs of your application. This manometer Dwyer simple, the wear Magnehelica moving parts, can be quickly directed to the low pressure of air or non corrosive gas - positive pressure, negative pressure (vacuum) or differential pressure can be. The design impact, shock, and with anti-pressure ability. No manometer fluid to evaporate, freeze, and will not cause toxic or leveling problems. In addition, its price is very low. This pressure gauge is widely used to measure the pressure of fans, blowers, filter resistance, wind velocity, furnace draft, the voltage drop across the orifice plates, foam level and pressure of the fluid amplifier or the pressure of the hydraulic system. It also checks gas - air ratio controls and automatic valves, and monitoring of pharmaceutical care equipment, blood and respiratory pressures. 
 Installation 
 Most Magnehelica manometer color shell of the same size. Can be surface mounted or flush mounting hardware provided with the product on the pressure gauge. A-610 pipe installation, and can easily install it on a horizontal or vertical of 1-1/4 "to 2" pipe. Although it is calibrated for vertical position, many ranges above 1 ", just for a simple re-zero can be used for any angle. However, in order to achieve maximum accuracy, they must be in the same location and use location calibration of these features makes Magnehelica manometer for both stationary and portable applications, are ideal if you want to flush mount a 49/16 "holes must be drilled. Each machine is equipped with complete installation and connection fittings and instructions. 
 Vent 
 If an application, the pressure is continuous, and Magnehelica manometer difficult to move the metal or plastic tube is connected, we recommend that you use the Dwyer A-310A vent valve to connect the pressure gauge. So that you can check the pressure gauge or pressure gauge zeroing remove the pressure. 
 High pressure and medium pressure 
 Similar pressure gauge and standard installation, but embedded is 4-13/16 "hole required for the installation. Medium-pressure structure to withstand the internal pressure of 35 psig, and high-pressure structure to withstand the internal pressure of 80 psig. A variety of range have a larger case, so I do not fit in carrying case weighs 1 lb, 10 oz (installed standard Magnehelica pressure gauge on the A-321 safety relief valves can be the sudden appearance of overvoltage manometer to provide adequate protection; see Bulletin of the S-101). 
 Physical data: 
 Ambient temperature range: 20 ° to 140 ° F 
 Rated total pressure: -20 "Hg. ~ 15 psig. 
 Pressure: bleed plug open about 25 psig. 
 Connection: 1/8 "female NPT high and low pressure pipe mouth two - side one, the back of one. 
 Housing: die cast aluminum housing, pickling aluminum, resistant to 168 hours salt spray test. The outer coating of dark gray. 
 Accuracy: ± 2% FS (3% -0, 4% -00 range), the entire range of 70 ° F 
 Standard accessories: two 1/8 "NPT plug for two pressure nozzles, two 1/8" pipe thread, for the rubber fittings. Three bolts countersunk mounting interface (mounting rings, press the retaining ring holder for the replacement of the three joints of the medium pressure and high pressure manometer attachment). 
 Weight: 1 lb 2 oz * Low temperature models also provide a #. For high-frequency pressure changes occasions, it is recommended that products with a higher rating. See the lower left corner of the high pressure and medium pressure models. 
 Options and accessories: 
 Transparent table cover with red and green indicator, used to emphasize the critical pressure 
 Variable message signs, and plastic case, one with an external adjustment screw. In addition to the medium and high pressure type, all the pressure range are equipped with this option. Can be ordered together with the pressure gauge can also be ordered separately 
 LED setpoint indicators bright red LED lights on the right side of the scale, when the pressure reaches a set fixed-point, LED lights will light. Can be scene from the dial to adjust the working voltage of 12-24 VDC. The needs of medium voltage or high voltage meter cover. 
 Portable products: 
 Combination of any of the standard range (non-pressure type) Magnehelica pressure gauge and carrying case. Including 9t. Length r 3/16 "ID rubber tubing, standard bracket and terminal tube with a fixer tube. 
 Air filter meter attachment: 
 In conjunction with any standard Magnehelica pressure gauge can be used as air filter count. Including the aluminum surface mounting bracket with bolts, two 5 ft long 1/4 "aluminum tubing pipe, two hydrostatic mouth, two molded plastic vent for fasteners at both ends and valves.
