Manufacturer product presentation
Series 3900 pressure switches are widely used in pilot duty applications and incorporate field adjustable set points and internal switch contacts. These switches convert a pressure signal to an electrical output. In response to a change in pressure, movement of an elastomeric diaphragm opens or closes an electrical circuit based on a predetermined pressure set point. The Series 3900 feature a compact size and a cost effective, combination terminal design which allows electrical connection with either 1/4" quick connect or #8 screw terminals. Pressure ranges as low as 6" Water Column (W.C.)* up to 5 PSI are available (1.5 kPa to 34.5 kPa). Series 3900 switches assure control stability through wide temperature and humidity conditions. As with all Tecmark® products, Series 3900 switches provide superior performance and uninterrupted service, even under extreme shock and vibration.
*27.7" water column = 1 PSI
Commonly used as an interlock device to sense positive pressure in pneumatic or fluid flow systems. Series 3900 switches provide on/off control of a variety of electrical devices including gas, electric, electronic ignition and millivolt (standing pilot) heaters in fluid flow systems as well as other electrical equipment.
The Series 3900 switches are intended for pilot duty control of electrical contactors and relays. In applications where the pressure switch carries higher electrical loads, use our Series 3000 or Series 4000 pressure switches.
Tecmark's manufacturing philosophy is unique. In an effort to provide you with a product that is most suited to your application, Series 3900 switches incorporate numerous interchangeable components for the ultimate in design flexibility. This means a product tailored to your needs without the high price and long lead times associated with custom manufacturing. If you have a need and don't see the features you require, please ask us!
