Industrial furnace & Water Heater Air Proving Switch
The Mamco / Lefoo LF-31 series switch was designed for the HVAC industry where safety and reliability are essential. This series has also proven to be a viable solution for many pneumatic OEM applications.
Available in vacuum, differential and pressure models, with fine silver or gold cross bar contacts. The LF-31 is capable of detecting pressures, as low as, .05" of water. Factory calibrated units maintain set point tolerances of +/- 10% over a temperature range of -40º F to 185º F due to it's molded silicone diaphragm and the stability of it's glass filled polyester body.
MAMCO offers multiple electrical terminations and mounting options, as well as, bleed holes and three different size orifices. This switch series is not only the leading product in the market offering the highest quality and reliability but is also the most economical. |

General Description
The ED101 series electronic module is used to control DSA/DWE/DWU pressure control valves manufacturers. The module accepts up to 4 on/off input signals which select one of four pressures set by potentiometer adjustments on teh card. Two ramp adjustments provide smooth transition between selected pressures.

MAMCO/LEFOO LF-20 INDUSTRIAL PRESSURE SWITCH
Because of its special internal design this switch can tolerate high pressure spikes inherent on many pressure systems. The switch is factory calibrated but in the case that adjustment is needed in the field the switch offers an adjustment screw to facilitate any fine tuning required. The standard diaphragm employed by Mamco is polyimide (Kapton) making it compatible with many gases and liquids. Several other diaphragm materials are available that make the switch compatible with many mediums. Various electrical terminations are available including ¼ tabs and a metric-pack connector specifications that forms a tight industrial seal when connected.
Because of their ruggedness the Mamco LF-20 is a popular choice for the many OEM applications. |

Electro-hydraulic pressure switches are devices, which, when set under pressure close or open electrical contacts. They are widely used in applications where it is intended that, once a pre-set pressure is achieved and exceeded, an electrical switching command or signal should be triggered for further working cycles.
Many different versions (with pressure setting on a dial, with main and secondary switch, screw-on pressure switches) enable their use in many applications.
There is a design related difference of 8 ... 20 % between the upper switching point and the lower switching point. Only the electronic pressure switch type DG 5 E gives provision to select two independant switch points
and to set the hysteresis.
Type DT is an analogical pressure sensor manufacturer. |

| Trafag pressure switches manufacturer are used when pressure has to be controlled or monitored via an electric on/off switching signal. These switches are available in various designs in respect of indication, switching capacity and approvals (CE, Ex, Shipbuilding, Railways) as well as the sensor system involved. In mechanical pressure switches, a industrial pressure sensor actuates an electric micro switch manufacturer. In electronic pressure switches, a pressure sensor signal controls relays or transistor outputs. |

Temperature: Ambient:-10 to +85
Electrical Connections: Tab terminals 6.4 X0.8 mm, Tab Terminals 4.8 x 0.8 mm (1 pole NO only)
Pressure Range: Pressure: +15 to+2500mbar
Tolerance:+/- 10% NO; +/- 15% NC
Vacuum: -600 to -15mbar
Tolerance: +/- 15%
Simple Line Connections: Pressure and Vacuum: Inlet 4.0 or 5.5 mm(up to 500mbar) Threaded inlet M10x1mm or 1/4 gas.
Almost no hysteresis
Medium: Non hazardous gas only
Contact carrying parts: Brass Silver plated (gold on request)
Membrane: Nitrile, EPDM, (Silicone, Perbunan on request)
If two points are required, two pressure gages with different calibrations should be employed. The method of fixing the tab terminals to the switch body does not allow for absolute air sealing. The switch is therefore not reccommended for applications where static vacuum has to be maintained. However, special models with additional pressure spring that allow for the vacuum to be connected to the pressure inlet side are available on request. |
