differential pressure switch
Can sense the difference between two pressure levels as well as positive and negative pressure. Switching point: Pressure: 5 - 800 mbar Vacuum: 10 - 800 mbar Contact arrangement: Single pole, single throw, normally open or normally closed (SPST N.O. or N.C.) Upper port can be delivered with a different orientation than the lower port This pressure switch is usually used to sense differences between two pressure levels, but can also be used to sense pressure or vacuum. The switch is optimised for use on circuitboards, therefore the electrical contacts are two 1.0 mm pins. Furthermore the upper part of the pressure switch can be delivered with a different orientation of the upper pressure port compared to the lower port. The low tolerance of ±5% in a wide range and low hysteresis are also features of this switch. The switching point can be changed by the user with a adjusting screw. The switch can be delivered as single pole single throw normally open or normally closed (SPST N.O. or N.C.) and with silver-alloy or gold-alloy contacts.
Differential pressure switch with three ports, this switch is designed for direct integration into the pressure system Switching points: Pressure: 3 mbar Contact arrangement: Single pole, single throw, normally open (SPST N.O.) For air and other non-hazardous gases This pressure switch has three ports. The two ports that are located in the same plane are connected and can be used to let gas flow through the switch, possibly lowering the necessary number of parts and easing integration of the switch. The third port can be used to sense differences between two pressure levels. The switching point is being set in the factory, very low switching points are also possible. The small design is intended for use on circuitboards, two pins serve as the electrical connection. The switch is being delivered as single pole single throw normally open (SPST N.O.). A positive pressure is defined as pressure from the side with two ports towards the side of the switch with a single port.
Pressure and differential switch with rotary control to set switching point Contact arrangement: Single pole double throw (SPDT) For air and other, non combustible, non agressive gases Multitude of models to cover 0.2 mbar - 50 mbar as a pressure switch or 0.1, 0.2, 1, 1.5, 2.5 mbar as a differential switch Model Switching point Differential PSW-A3-02 0,2 ~ 2 mbar 0,1 mbar PSW-A3-03 0,3 ~ 3 mbar 0,1 mbar PSW-A3-04 0,4 ~ 4 mbar 0,2 mbar PSW-A3-05 0,5 ~ 5 mbar 0,2 mbar PSW-A3-10 2 ~ 10 mbar 1 mbar PSW-A3-25 5 ~ 25 mbar 1,5 mbar PSW-A3-50 10 ~ 50 mbar 2,5 mbar This pressure switch is outfitted with a rotary switch to facilitate changes to the switching point by the user. During normal operations the rotary switch is protected by a plastic cover, while allowing the set switch point to be read. Especially when multiple units are used in identical settings this reduces work load and saves time during setup. The included plastic cover of the pressure switch offers a protection level of IP54. Usually this switch is used to monitor the air flow in ventilation systems and heat exchangers. The device is available as a single pole double throw (SPDT) switch. Furtherfore the switch is also capable of sensing differences between two pressure levels. Assembly is possible with the holes in the feet.
Pressure switch for air, natural gas, combustion gases Switching point: 10 mbar Contact arrangement: single pole single throw normally closed delivery: with 90° mounting plate The pressure switch was originally intended for air conditioning units and therefore designed with a long service life in mind. The sturdy design and low tolerance of just ±5% throughout a wide range of temperatures allow its use in a lot of pneumatic systems. This series not only offers high quality and reliability, but also competitive costs. The requested switching point is being set in the factory, also considering hysteresis of the switch and the customer's choice of falling or rising pressure for the switching point. The switch is also being labeled with the switching point information. The type of switch can either be single pole single throw normally open or normally closed or single pole double throw (SPST N.O., N.C., SPDT), thereby allowing a range of applications. Furthermore silver-alloy or gold-alloy contacts are available. A metal assembly sheet with screws is included to facilitate the use of this switch.
For air, water, engine and hydraulic oils, paraffin, other hydrocarbonsSwitching points adjustable between 0.5 bar and 6 bar (with various models)Available versions from stock: PSW-M2D2 (0,5 - 2 bar, max pressure 16,5 bar) PSW-M2D4H (0,5 - 3,5 bar, max pressure 33 bar) PSW-M2D6H (1 - 6 bar, max pressure 33 bar)Electrical version: single pole, double throw (SPDT)This differential pressure switch is designed to monitor the differential pressure in oils. The pressure applied between the two measuring points is not only monitored by the set switching point. The optical scale also provides a direct view of the set switching point. The higher pressure is applied to the lower connection. This pressure switch is used, for example, for simple monitoring of valve functions, oil filters and oil pumps, as well as system components in compressed air systems, but also has a high electrical capacity to switch consumers directly.
