Introduction
Weather series pressure switches have a variety of micro switches and a variety of process connection options, making the 400 series UE pressure switches to meet a variety of different needs.
Because of its characteristics, the 400 series pressure switches are widely used in the protection and control, industrial process equipment and pumps, gas turbines, compressors, pulp and paper, water and sewage treatment industries.A wide variety of microswitch and process connection options, along with a weather-tight enclosure, make the 400 Series an ideal choice for most ordinary location applications. Its worldwide use is assured with approvals and certifications to agency standards.
Widely used throughout the process industries, the 400 Series provides threshold protection and control for many critical functions.
Typical installations are found in industrial gas production, energy generation including pumps, turbines and compressors, pulp and paper, and water and wastewater treatment.
Features
• 1, 2 & 3 switch outputs
• Epoxy-coated enclosure designed to meet enclosure type 4X
• Wide variety of pressure sensors and materials
• Setting via reference dial or hex screw adjustment
• FM approved
• Adjustable Ranges:
"WC ranges: 300 " wc vacuum to 250’’ wc pressure (-746,7 to 622,3 mbar)
Pressure: 30"; Hg Vac to 6000 psi (-1,0 to 413,7 bar)
Differential Pressure: 1" wcd to 200 psid (2.5 mbar to 13,8 bar)
Temperature: -180 to 650 °F (-117.8 to 343.3 °C)
Specifications
| Storage temperature | -65 to 160°F (-54 to 71°C) |
Ambient temperature limits | -40 to 160°F (-40 to 71°C); set point typically shifts less than 1% of range for a 50°F (28°C) ambient temperature change |
Set point | Temperature models: ± 2% of full scale range |
Repeatability | Pressure models 126-376, 520-535, 540-547, 570-572, S126B-S164B: ± 2% of full scale range; models 440-457, 550-559: ± 1% of full scale range; models 610-614: ± 3% of full scale range |
Shock | Set point repeats after 15 G, 10 millisecond duration |
| Vibration | Set point repeats after 2.5 G, 5-500 Hz |
| Enclosure | Die cast aluminum, epoxy powder coated, gasketed, captive cover screws |
| Enclosure classification | Designed to meet enclosure type 4X requirements |
| Switch output | One, two or three SPDT switches, may be separated up to 100% of range except models 521-524, 531-534: 50%; models 520, 525, 530, 535, 570-572: 30%; switches may be wired “normally open” or “normally closed” |
| Electrical rating | 15 A 125/250/480 VAC resistive. Electrical switches have limited DC capabilities. Consult factory for additional information. |
| Weight | Approx. 3 to 7.5 lbs.; varies with model |
| Electrical connection | One 3/4” NPT and two 7/8” diameter knockouts |
| Pressure connection | All models 1/4” NPT (female) except models S126B-S164B, 520-535: 1/2” NPT (female); models 540-547: 1/8" NPT (female) |
| Temperature assembly | "E" types use the same assemblies as "F" types, however, range spans are limited due to use of reference dials Bulb and capillary: 6 feet 304 stainless steel Immersion stem: models 120 &121: nickel-plated brass; optional 316L stainless steel available |
| Fill | Temperature Models: Model 1BS: solvent filled; models 2-8: non-toxic oil filled |
| Temperature deadband | Type F typically 1% and type E, B & C typically 2% of range under laboratory conditions (70°F ambient circulating bath at rate of 1/2°F per minute change) |
| Differential pressure indicator | Differential pressure indication available J400K, J402K models 147-S157B; accuracy approximately 1-1⁄2% mid 50% of range, 3% at ends; window is (option M210) plexiglass and gasketed; indicator may be field adjusted for approximately ±1% accuracy at any set point within range |
