Series 3900 Pressure Switch Specifications
Series 3900 Pressure Switch
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
Typical Applications
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.
Basic Construction
Visual scale for adjusting pressure setting in the field
Elastomeric diaphragm eliminates the need for an oil barrier
Internal switch contacts
A combination terminal design offers both 1/4" quick connect and #8 screw terminals
Built in over pressure protection designed to eliminate stress on other critical operating components
UL Recognized, CSA certified, as an operating, limit or safety control.
SPST switching logic
Available Features
Pressure ranges as low as 6" WC up to 5 PSI (1.5 kPa to 34.5 kPa)
