DWYER INSTRUMENTS Flow Switches

Debietschakelaars van Dwyer Instruments zijn ontworpen voor het leveren van elektrische feedback bij een specifiek debiet in toepassingen zoals boilers, warmwaterverwarmers, koelmachines en hydropneumatische tanks. Deze units hebben een magnetisch aangedreven ontwerp met een weerbestendige en explosieveilige behuizing voor toepassingen buitenshuis en een zijwandmontageconfiguratie voor gemakkelijke toegankelijkheid en snel onderhoud. De serie V10 Flotect-stromingsschakelaars van het merk maken in het veld gekalibreerde schakelaaraanpassingen mogelijk om te schakelen tussen NO (normaal open) of NC (normaal gesloten) werking; waardoor het niet meer nodig is om met de elektrische aansluitingen te knoeien. Kies uit een breed scala van deze producten, verkrijgbaar in buismaten variërend van 1/2 tot 2 inch Raptor Supplies, een geautoriseerde distributeur van Dwyer Instruments.

Voordelen

  • These units feature a magnetic-actuated design with a weatherproof and explosion-proof body for withstanding outdoor applications.
  • They have side wall mounting configuration for easy accessibility and quick maintenance.
  • Dwyer-instrumenten V10 liquid flow switch allows field-calibrated switch adjustments to toggle between NO (Normally Open) or NC (Normally Closed) operations, eliminating the need to fiddle with the electrical connections. It features brass construction for corrosion resistance and durability. This Dwyer flow switch has a hermetically sealed reed switch with magnetically actuated switching mechanism and a field-trimmable, full-size vane for user convenience.
  • Dwyer-instrumenten V8-WP liquid flow switch features polyphenylene sulfide construction for durability and making it weather proof. It can be operated at pressures up to 150 psig and temperatures up to 212 degrees F (100 degrees C). This flow switch has a SPDT switch to allow ON / ON configuration, which means the switch's input terminal is always completing one of the two possible circuits that the switch controls.

Veelgestelde Vragen

How to install this Dwyer flow switch?

  • Make sure you carefully unpack the switch and take any packaging out of the lower housing.
  • The vane should be trimmed at the proper mark depending on the pipe size being utilised.
  • Install the switch in the system piping with the arrow on the side pointing in the direction of flow and then apply pipe thread sealant to the 1/2 inch male NPT mounting threads.
  • Install wiring in accordance with regional electrical regulations.
  • When assessing system loads and currents, use caution. After installation, set the switch action to NO (usually open) or NC (normally closed).
  • When a reed switch is activated by an increase in flow, usually closed connections open and normally open contacts close.
  • The two screws on the top cap must be loosened but not removed in order to replace them.
  • To reveal the specified switch action, slide the reed switch assembly.
  • When the adjustment is finished, tighten the screws.

What is the difference between inductive, capacitive and lamp load current ratings?

An inductive load is due to an electromagnetic solenoid, electromagnetic relay and electromagnetic counter with an inductive component as a circuit load. A capacitive load is a capacitor connected in series or parallel with a reed switch control. In a closed circuit, a cable length, generally greater than 50 metres, is used to connect the reed switch which may also evolve static capacitance. A lamp load can occur because of a tungsten filament lamp load.

What do actuation and de-actuation mean?

Actuation refers to the phenomena when a microswitch trips or the contacts of a microswitch change their state. De-actuation occurs when the flow rate is low enough for the microswitch to revert to its default setting.

Does Raptor Supplies provide DPDT switch variants of Dwyer Instruments flow switches?

Yes, Dwyer Instruments V6EPB-B-D-2-MI flow switch features a DPDT switch that and is available on Raptor Supplies.
